Experimental Investigation of the Impact of Cable Length and Type on Motor Overvoltages, Shaft Voltage, and Bearing Currents in PWM-Inverter-Fed Drive Systems
Fast-switching transients and high dv/dt associated with PWM inverters exacerbate the reflected-wave effects in the motor feeder cable. This leads to higher motor-side overvoltages, which increase the stress on the motor winding insulation, potentially accelerating insulation degradation and increasing the risk of part...
