Hi, I am working on an EV and the problem is in sizing or selection of dc motors. I have to select few small PM DC motors instead of a big one, the purpose is to pull a wheelchair, I have the mechanical quantities with me required to turn a wheel:
Torque required is 43 N-m
Power required = 135 W
w(angular velocity)= 3.14 rad/sec
I want to use 24 v supply for the parallel combination of the dc permanent magnet motors, now first thing how to select the motors and while selecting the motors what should I do?
1) Is it correct to consider the amount of current flowing through the parallel combination of motors as equal in each motor?
2) and is sum of all the torques produced by each motor is equal to my mechanical torque required?
please help me out, thks!
