3 Types of Electric Motor For EV Which Will Give You The Most Torque




-DC series wound electric motor:


The main attraction of this category is the fact that all the torque is available from a standstill. People usually make the mistake of identifying this as a special feature of electric cars. This is a wrong notion.

It is an exclusive quality of the motor. But this type of motor is not without any flaw. This is not good at climbing the hill.

According to them, the motor fails where a relatively constant speed is required under conditions of varying load. You can just imagine what it would be like when you are using your electric vehicle (EV) traveling on a hilly area. The DC series motor might not climb hills too briskly.

Running without load this motor will fail you. It will turn with enough force to damage itself without load. Traveling can become a nightmare to the concerned person in such a situation. However The Advanced DC Series Wound Motor stays at the top in popularity in the category of electric car motors followed

2) Permanent Magnet DC Electric Motors:





The spite of having a lot of drawbacks this one still ranks second in the category of electric car motors in popularity. All brushed DC motors generates electrical radio interference. The process of filtering electrical noise by windings does not take place in this motor.

The permanent magnet motors have no natural filtering effect in their design. That is why they are noisy. That is the biggest disadvantage as far as this category is concerned. Because of this a lot of people shy away from purchasing this magnet based motor. Let us discuss the third one.

Wheel hub motors.






The AC system works pretty much the same but requires a lot more things like six times the amount of transistors to change the DC voltage from the battery to AC, and it gets kind of hard to explain simply!

Electric motors are a pretty hard concept to understand for someone who never heard of them before. I just finished secondary school and I remember spending many classes just learning how the basic AC and DC motors work!
But there's no real need for you to know why electric car motors work, you just need to know the advantages and disadvantages.


This definitely isn’t the most technical information you could get. There’s plenty more advice out there, especially on the internet.
I have to warn you though if you’re not careful you could spend days going through the technical aspects and not end up learning anything useful, so
