- Brushless DC Motor
It is called brushless because it does not have the commutator and brush arrangement. The commutation is done electronically in this motor because of this BLDC motors are maintenance free. BLDC motors have traction characteristics like high starting torque, high efficiency around 95-98%, etc. BLDC motors are suitable for high power density design approach. The BLDC motors are the most preferred motors for the electric vehicle application due to its traction characteristics. You can learn more about BLDC motors by comparing it with normal brushed motor.
AC Induction Motor
The AC Induction Motor (ACIM) is the workhorse of the motor world. It is the most common motor type, used in everything from consumer products to heavy industry and electric vehicles . Its simple design with no brushes makes it highly reliable and allows it to be manufactured at a low cost. However, it is less efficient than other motors like the Permanent Magnet Synchronous Motor (PMSM), which is partially related to the heat generation in the rotor windings.
Permanent Magnet Synchronous Motor
Permanent Magnet Synchronous Motors (PMSMs) are brushless and have very high reliability and efficiency. Due to their permanent magnet rotor, they also have higher torque with smaller frame size and no rotor current, all of which are advantages over AC Induction Motors (AICMs). With their high power-to-size ratio, PMSMs can help make your design smaller without the loss of torque. PMSMs need to be commutated like BLDC motors, but due to the construction of the windings, the waveforms need to be sinusoidal for good performance.
Interior Permanent Magnet Motor
A type of motor that has a rotor embedded with permanent magnets is called the IPM (interior permanent magnet) type. Compared with the SPM (surface permanent magnet), this type of motor can reduce the risk of a magnet being peeled off by centrifugal force, and take advantage of reluctance torque. The IPM type allows various structures for embedding permanent magnets.
Permanent Magnet Synchronous Reluctance Motor
Permanent Magnet Synchronous Reluctance Motors are receiving much attention due to their high speed, power density and efficiency characteristics. The permanent magnets made of rare earth and neodymium have lower inertia compared with Induction Motor because of elimination of rotor cage. Hence torque to inertia ratio of PMSRM is higher. As PMSRM has negligible rotor losses, their efficiency is high. PMSRM has the excitation in the form of the rotor magnet, hence no external source of magnetizing current for excitation is required like an induction motor. Since rotor losses in PMSRM is small, the loss in the form of heat is avoided which improves the performance of the motor. PMSRM is smaller in size and has lesser weight. It is suitable for the applications where the size of machine is limited.

BLDC motor runs on DC supply while PMSM runs on AC supply.
Ather 450 used BLDC motor while 450X and 450+ uses PMSM.
Yes thanks for correction new generation ather scooters has PMSmotor . That's why it's very costly.
Axial Flux Motor is used in many hybrid vehicles.
Motor + battery + controller combination for long distance in single charge for ev
Par ek dedicated video provide kijiye
You'll get be subbed by the people i know 😊😊😊
Thanks for the video
Sharing video to everyone
Thanks
❤❤❤😮 बीवी कोई अप🎉पी😊😊
Plz make a video on battery used in electric vehicles.
Informative video thank you so much
❤❤❤❤❤❤❤
Brother most powerful motor jo 100 over ki speed pakade or load uthaye please video banawo
Hi Sir, I am research scholar. I wana do research on Electric motor in EVs. If u dont mind can u suggest some topic/area about motors in EVs which will be useful in future.
I have, that can be also patent with shared
बैटरी से चलने वाली मोटर के दाम बताइए
Best
Thanks
PMG Alternator (generator) ke bare me btaiye sir.
Tnku❤
Welcome
nice 👍
Can dc motor be used in electric vehicle?
We can use in scooty & Activa ac motor vehicle. Show more videos on ac moters thankyou sir please
Kya ye sari motor liquid cooling battery se chal sak ti he kya

KHA.MILEGH YEH
Kya auto and toto mein motor hota hai
In sbke price बताना bhulgye
ताकत और पावर ओर किस मैं बेस्ट है और चकर कोन सी ज्यादा है
टेक्टरों कोन सी होती है
Bro you said BLDC operates on AC and PMSM operates on DC.......
This is completely false statement bro.....Iam an engineer and when I heard it I was really disappointed.....
Make the correction in the video if possible....Time lapse(2:07 to 2:15)...
Thanks
