    The love and appreciation for the team that makes and delivers these videos can be difficult to really convey because it’s highly regarded, so as well is the person narrating the videos. I worked for years as a Tech in the Utility Plant Environment around many equipment with Soft-starters as well VFD’s and never quite understanding properly quite how they worked in a properly explained way like explained by RealPars. I feel so much appreciation from the care taken to make these videos in explanation in demystifying industrial automation understanding. I’m so much smarter because I’m here!

      Technology is fascinating. I am just a young adult who is interested in science and technology, and was hoping that there was a device that can reduce flickering of the lights when the air conditioning starts (current inrush). Apparently, someone invented it: the soft starter, and RealPars explained it so well (visual learner here). 10/10 good video. :)
      *Would be nice if air conditioners, dehumidifiers and fridges could gently start up. Sadly, domestic air conditioners typically don't have enough inertia to necessitate a soft start system, which can cost a lot of money. Also, the flicker of the lights occur for just 1/10th of a second. Thankfully, most my bulbs are LED, so only one or two incandescents flicker. Also, variable stage air-conditioning does exist, and they use similar motor ramp-ups to alternating current soft starts to reduce initial energy consumption.

    I'm planning a whole house backup generator which includes running my 3 ton Air Conditioner. The problem WAS my AC was blowing my budget because it would require an 8000 watt minimum generator to handle the initial startup of the unit. I found this soft starter and installed it on my AC (took about 10min.) and now I can run my entire house on a 3500 watt generator. Saved me $$

    I build a simple soft starter circuit for use on some of my power tools. The big problem is that I must manually through a switch on the starter itself while the tool's switch is closed. Works great, but a hassle and dangerous. I wish someone came out with a small size retrofit addon kit for saws and other high surge current motors that don't NEED to have balls out instant starting.

    @MrFernandoBedoya 4 ปีที่แล้ว

    At 3:10 I see the soft starter and, besides (parallel) a contactor. So, my question is : How these two components work together? It could be that when the motor starts only the soft starter works, then, when the frequency and voltage are adjusted (by the soft starter), the contactor is activated and the soft starter disconnected.
    To me that's the explanation. But, another doubt : When we hit the stop button...Is the process the inverse of the starting? , I mean, both contactor and soft started are connected, the the contactor i disconnected and at the end only the soft started is stopping the motor?
    I will appreciate your explanations.

    • @realpars
      @realpars  4 ปีที่แล้ว +1

      You are likely correct on the use of the parallel contactor. It is also possible that this particular motor is used in two different modes, one requiring a soft-start and one that does not. Although not completely drawn correctly, Siemens does make a line of motor monitoring modules that is installed in parallel and is cabled to the main motor controller, but I would believe your suggestion is most likely correct.

      Hello Jonas Granlund,
      Thank you for your question.
      Unfortunately, I can’t answer your question, because I don’t know your application and your engineering setup. But I can suggest you look at your soft starters’ manual graphic charts to help you with your torque load and speed output at your load requirements. It should address the amps used for your settings. And make sure you have the wire feed sized correctly to handle the load.
      Happy learning!

    • @jonasgranlund4427
      @jonasgranlund4427 ปีที่แล้ว

      @@realpars Thank you so much for the response, when I look at the graphs and read the manual I get the feeling that the Current limiting mode is a little more advanced and reduce voltage when the Current start to overshoot the set-value. But I'm not sure how high I dare to set the current limit and the amount of second it needs to be delayed. This is what the manual say about this start mode: The current limiting starting mode is generally used in occasions with strict
      requirements on starting current, especially when the power grid capacity is too small.
      To limit the starting capacity, the current limiting multiple can be set according to
      the requirements, which is generally between 2.5 and 3 times. If the setting is too
      small, the normal starting will not be possible. When current limiting starting is
      adopted, the starting time is related to the current limiting multiple.

    Do we need soft starters for hydraulic motors? Is there a a high inertia load in hydraulic motors compared to your large fan example in the video?

    • @realpars
      @realpars  4 ปีที่แล้ว +1

      Torque is proportional to inertia The torque required for a hydraulic motor is dependent upon the fluid flow rate and pressure developed in the hydraulic lines (usually >1000psi). So, yes, hydraulic motors can have high torque requirements. For hydraulic systems, power clutches are used to regulate the starting pressures (hence, torque and inertia). These devices are not really soft-starters, but rather hydraulic "regulators" that act similarly to reduced voltage motor starters.

    Normally how many additional years will you add up to the life of the motor when using a soft starter compared with a full voltage starter?

    • @realpars
      @realpars  3 ปีที่แล้ว +1

      Great question, but difficult to answer. Life of a motor depends on a host of factors, but using a properly sized, installed, and configured soft starter should extend the life of your motor by up to 25%. The normal life of a motor in years has too many variables to make a quantitative assessment of increased life in years. That all depends on the load, torque requirement at startup, motor design, and how the motor is run (frequent start/stop?, etc.).

      Yes, a soft starter would limit the amp draw when the motor is first started. With a high starting torque requirement, the starting amps would be significant. A soft starter would provide a smoother start, but it will take a little longer to come up to speed. However, the possibility of popping a fuse at start is greatly reduced.

I also think that appliances like air conditioners which are still 100% on or off are inefficient. Any large appliance that could potentially have any savings starting slower like an air conditioning compressor unit, HVAC fan, washing machine, oven, stove you name it, seems like everything should start slowly to save money. Or at least have an optional setting to do so like an eco mode.

    I dont think people understand the amount of current these large electric motors use. I saw an accident where the motor was physically isolated while fitters aligned the shaft. The apprentice was given the job of stripping and installing wires to the first junction box (safely isolated under permit). While aligning the shaft it is necessary to very slowly rotate the shaft 90 and then 180 degrees. Just a very slow quarter turn on the shaft was enough to generate quite shock and injure the apprentice. Heads did roll because anyone with a high voltage license should have known this. Hard instead of soft start at the same time as an alignment problem nearly bought down a five story structure with me on it and does do a lot of damage to a lot more than just the motor and system it is powering.

    Nice explanation of a soft starter. Can they also be used to power up step-up transformers? Where I live, i have 230V 3-Phase. My work shop main line is 16A 3-phase, 230V. Most of my machines run on 400V 3-phase, so i have a small transformer that is rated at 16A inlet and 10A outlet. Almost every time I switch on the thransformer circuit (through a contactor) the 16A circuit braker trips. This is due to high inrush current i believe. Some times i have to try 3-4 times or more before i can switch on the ciruit without tripping the breakers. Note, the circuit is unloaded when switched on. I never have problems when putting load on the circuit, such as motors etc.
    Is this an application for a soft starter? Thanks.

    • @realpars
      @realpars  5 ปีที่แล้ว +1

      The current on the secondary side of a step-up transformer will be less than that on the primary, since power (V x A) is conserved (minus a little efficiency loss). However, since the secondary (as well as the primary) are inductive loads, they behave somewhat like a motor would, with the possibility of a larger inrush current. I would use properly-sized time-delay fuses on the primary feed instead of the breakers you are currently using. This will likely fix your issue. You could try a soft-starter, but that will be expensive by comparison, and may not fix your issue.

    Instant of star/delta circuit we can use soft starter?

    • @realpars
      @realpars  5 ปีที่แล้ว

      The short answer is YES, since both limit the line voltage on start. The electronics inside of the soft starter represents an improvement over the star-delta (or wye-delta) starter arrangement, and soft starters accomplish the same benefits at a higher efficiency.

    inrush... is not "voltage" BUT CURRENT!!
    From 5 to 7 times the run current
    The bigger the motor the more destructive is its INRUSH CURRENT at start up time.
    VFD Soft-starters ramp up the PHASE FREQUENCY there by limiting the current required NOT the voltage.

      A triac affects the voltage too.

    • @johncochran8497
      @johncochran8497 5 ปีที่แล้ว

      Yes, the intent is to reduce the inrush current. But the control is via voltage. The triacs in the soft starter are triggered at a specified voltage of the incoming waveform to limit the voltage seen by the motor and thereby reduce the current consumed by the motor.

    • @joeanne6258
      @joeanne6258 5 ปีที่แล้ว

      Low voltage=high current
      High voltage=low current
      Therefore if you intent to lower the current you need to adjust the voltage.

    • @johncochran8497
      @johncochran8497 5 ปีที่แล้ว +2

      @@joeanne6258 No. We're not talking about a transformer where you're converting voltage and amperage while keeping wattage constant. We're talking about inrush current which is effectively determined by Ohm's law I=V/R. Since we can't do anything about the resistance, we decrease the available voltage via the triac.

      Hi John,
      That's a good question, thank you! You will have to look at the data spec sheet of your air conditioner. There is a soft starter for AC units on the market, and some AC have them build it. Depending on your needs and budget. The soft starter must be connected between the controller and the motor units you want to control.

      Every manufacturer's soft starter is a little different, but most require that you set the line voltage, full load amps, current limit, and torque boost. Beyond that, acceleration, deceleration time, and other parameters specific to that manufacturer's drive are set via a front panel interface or serial programming interface. While VFD's may have 100+ configuration parameters, soft starters usually require less than 10.

    What is the difference between a soft starter and a vfd?

    • @scottsommer5450
      @scottsommer5450 5 ปีที่แล้ว +2

      A VFD varies the frequency of the three-phase power delivered to a motor to allow its speed to be varied. A soft-starter is used on an "across-the-line" starter to limit the initial in-rush of current to the motor so that it starts in a more controlled way over a short period of time (seconds).

    • @ardentdfender4116
      @ardentdfender4116 5 ปีที่แล้ว

      NURUDEEN There is also a new current video explaining this and well explained. In my 2 cents also a VFD has more variable speed control of the motor or a motor where it needs a specific ramp up or down speed as well as may need to run at a specific variable speed that’s not also full speed.

      Yes. PM motors should use a soft-start or VFD for starting and control to avoid large current inrushes that may lead to motor or component failure. It is always best to check with the manufacturer of the drive you wish to use to see if there are any recommendations for use of their devices with PM motors. Some manufacturers, such as Yaskawa, have specific models or features that are provided specifically for use with PM motors.
