Dc motors

  1. Feb 7, 2009 #1
    In a conventional DC motor 95 percent of the power is supplied to the motor while only 5 percent of the power is supplied to the stator. consider the torque equation. what if you have a motor that has 95percent power supplied to the stator and 5 percent to the motor. the motor will still run but why do we not use this motor?

    It sounds like you're referring to the motor efficiency. If the shaft output is only 5% then the motor is not very efficient. So it would not be economical to use it.
