The benefits of installing a Pulse Width Modulated (PWM) Drive, including increased energy savings and decreased maintenance, may make it seem like the perfect solution. But, these benefits can be offset by increases in motor failures. Voltage wave reflection is a function of the voltage rise time (dv/dt) and the length of the motor cables. The impedance on either end of the cable run does not match, causing voltage pulses to be reflected back in the direction from which it arrived. As these reflected waves encounter other waves, their values add, causing higher peak voltage. As wire length or carrier frequency increases, the overshoot peak voltage also increases. Peak voltages on a 480V system can reach 1,600V and 2,100V on a 600V system. These high peak voltages can cause a rapid breakdown of motor insulation, leading to motor failure.
