How can we determine the effective voltage of a 5 hp DC motor when it is delivering its rated horsepower?

Question

Michael · Answer

Calculation of Effective Voltage     Effective voltage is a crucial factor in determining the performance of an electric motor. In the case of a 5 hp DC motor delivering its rated horsepower, we can calculate the effective voltage using the formula: Ia = P / Ea, where Ia is the armature current, P is the power in watts, and Ea is the applied voltage.
