Types of Motors used in Electric Vehicles

Electric cars aren't something new to this international, however with the technological development and accelerated concern on controlling pollution has given it a tag of destiny mobility. The middle element of the EV, apart from Electric Vehicle Batteries, which replaces the Internal Combustion engines is an Electric motor. The fast improvement in the field of Power electronics and control techniques has created a space for diverse kinds of electric powered vehicles to be used in Electric Vehicles. The electric cars used for automobile programs must have characteristics like high beginning torque, excessive electricity density, suitable efficiency, etc.

Various forms of Electric Motors used in Electric Vehicles

DC Series Motor

Brushless DC Motor

Permanent Magnet Synchronous Motor (PMSM)

Three Phase AC Induction Motors

Switched Reluctance Motors (SRM)

1. DC Series Motor

High beginning torque capability of the DC Series motor makes it a appropriate option for traction application. It changed into the maximum widely tamilrockers proxy sites used motor for traction utility inside the early 1900s. The advantages of this motor are easy velocity manage and it can additionally resist a unexpected boom in load. All those characteristics make it a super traction motor. The primary downside of DC series motor is high renovation due to brushes and commutators. These vehicles are utilized in Indian railways. This motor originates under the category of DC brushed vehicles.

2. Brushless DC Motors

It is similar to DC automobiles with Permanent Magnets. It is referred to as brushless as it does not have the commutator and brush arrangement. The commutation is done electronically on this motor due to this BLDC automobiles are preservation loose. BLDC cars have traction traits like excessive starting torque, excessive efficiency round 95-ninety eight%, and many others. BLDC vehicles are appropriate for excessive energy density layout method. The BLDC cars are the most favored motors for the electrical car software due to its traction traits. You can study greater approximately BLDC automobiles by evaluating it with regular brushed motor.

BLDC motors similarly have two kinds:

i. Out-runner kind BLDC Motor:

In this type, the of the motor is gift outside and the stator is gift internal. It is also called as Hub vehicles because the wheel is without delay connected to the outdoors rotor. This sort of motors does not require outside gear system. In a few instances, the motor itself has in-built planetary gears. This motor makes the general vehicle less cumbersome because it does now not require any equipment device. It also removes the space required for mounting the motor. There is a restrict at the motor dimensions which limits the electricity output in the in-runner configuration. This motor is extensively favored via electric powered cycle producers like Hullikal, Tronx, Spero, mild speed bicycles, and so on. It is also utilized by two-wheeler manufacturers like 22 Motors, NDS Eco Motors, and many others.

In this type, the blade of the motor is gift internal and the stator is outdoor like traditional motors. These motor require an outside transmission machine to transfer the energy to the wheels, due to this the out-runner configuration is little cumbersome whilst as compared to the in-runner configuration. Many three- wheeler builders like Goenka Electric Motors, Speego Vehicles, Kinetic Green, Volta Automotive use BLDC cars. Low and medium performance scooter producers also use BLDC cars for propulsion.

It is due to these reasons it's miles broadly favored motor for electric powered vehicle application. The fundamental downside is the excessive fee due to permanent magnets. Overloading the motor past a certain restrict reduces the life of everlasting magnets because of thermal situations.
