Motor Noise With Vfd. However, shielded and properly grounded cables can prevent detrimental paths to earth. Vfds can wreck motor windings. Common mode noise produced by pwm travels throughout the motor to ground. Both the maximum value of the voltage pulse and the rise steepness (dv/dt) are dangerous for the motor insulation. Vfds control motors with a simulated sine\ wave known as pulse width modulation (pwm). The amount of noise produced can be affected in a number of ways when the motor is controlled by a variable frequency drive (vfd). The result is high voltages and currents which may contribute to nuisance controller faults, premature failure of motor bearings, and motor windings. The insulation of motors with a rated voltage of 400 v is not significantly impaired if the maximum voltage umax < 1000 v and the steepness of the voltage du/dt < 500 v/μs. Adding a ferrite (or referred to as ferrite choke) between the motor and the variable frequency drive may help eliminate or reduce. Vfds can induce common mode voltages in the motor windings and shaft, which can exacerbate emi.
