The way to make the correct economical choice is to evaluate the life-cycle cost, which includes the purchase price plus an estimate of future operating costs and length of service. The longer high-efficiency motors are run, and the higher their duty cycles, the more energy they ...

The purchase price of a motor might account for only 1 to 2 percent of the total cost, including energy costs, of running a motor for 10 or 20 years. Compared with older standard or EPAct efficiency motors, a high-efficiency motor — one that exceeds EPAct minimums by a wide marg...

While both A.C. and D.C. motors serve the same function of converting electrical energy into mechanical energy, they are powered, constructed and controlled differently.

Most of hybrid vehicles such as Toyota Prius use high voltagemotors which reach voltages beyond 500 V.Such high voltages are dangerous and require assembly frommany hundreds of batteries.In one place I`ve read that powerelectric motor draws is related to volts...
