    I had a doubt while choosing an dc motor for a college EV project. While calculating the torque on my motor I had considered two factors : 1. The weight of the car. 2. Aerodynamic drag force. So, while looking at motor datasheets and considering the load on motor, why should I consider the...

    Hello All, You may have seen my posts on other threads about a motor model I am developing. Well, I am pretty happy with it and so let me explain. First, the torque generated by a motor is given by the armature current times the "field" times some constant depending on the motor structure and...
