- Scalar Control and Vector Control Mode are the two VFD Control Modes deployed in various applications encountered in industries which ensures better efficiency of motor and power saving as well. @Instrumentation Unlimited
VFDs have been there in industries for quite a long time for control and power-saving purposes. Right control methods selection and configuration of VFDs ensure efficient operation of motors and promise reduced downtime. This video explains control methods employed in various applications found in any industry. Kindly post comments or any query you encounter during the video on dineshdiwani@gmail.com

Nicely explained , Thank you
Good learning
Sir, Thanks for proper information.
Very informative video. Pls. make video on d.c drive & servo drive.
Sure..
Nice sir
👌👌
Sir VFD ke input current and out put current me defrence kyu hota he jabki starter me nhi hota ?
Vfd output supply voltage below 50 Hz is below the line voltage so to fulfill condition of Pin=Pout the output current must be higher than the input. If we consider 50% speed the output voltage will be half but output current will be double to fulfill Pin=Pout condition. Some losses occurs in vfd so output current is slightly less than double of inout current.
pulsed dc how can be converted to sine wave please explain
These pulses are passed through a windings of motor which are an inductor. As we know an inductor opposes any current change. The moment inductor saw a pulse it retards sudden current change. When dc pulses of varying width is passed through winding... A sine wave appears across its winding
@@dineshdiwani and sir you have talked about 200 torque with no rpm is it magnetic locking = cogging
@@workbyvivek6557 that is the condition when vfd is operated in vf mode with frequency at zero and rated voltage is applied. But in vector control two diffrent imaginary vectors contros magnetizing current and torque producing componet separately. In that case motor is actually running at 0 rpm with full torque.
Sir motor name plate
400volt 6000rpm 104hz me he
Vfd per chlane per frequency 55 se uper nahi jyati
Vfd me fd mode set ker rakha he kya problem ho sakti he sir
VFD me Max freq kitni set hai? Check kro
Sir vfd me maximum frequency 104 he
@@satishpawar110 then no issue it will deliver output at 104 hz maximum... You specifically told it is delivering output at 55 hz... I think this setting is lock in setting menu. Check again. Or check motor data if it is has been feed correctly.
stop reading what written in front of u ..instead explain the things if u can ....humble request
Sure... Make a question? If you had any by watching video. I will try to explain you if i can.
@@dineshdiwani sir ur material is grt but explanation is too fast....may be u want to make smaller video.....
@@shankarsahni nobody wants to hang up on phone for half an hour. Its not movie. Majorly i try to explain thro pictorial presentation so that if you miss any point can get it from pitorial presentation and cover practical aspects only assuming you working on these system ao that you can relate with your experience.
