VFD & Motor Protection

Variable frequency drives (VFDs) are electronic devices used to control the speed and torque of AC motors by varying the frequency and voltage supplied to the motor. Along with their speed control capabilities, VFDs incorporate several motor protection features to safeguard the motor and its associated equipment.

Motor protection is a critical aspect of VFDs, and they incorporate a range of protective functions to prevent motor damage and ensure reliable operation. These protection functions include overload protection, short circuit protection, stall prevention, and current limitation. Overload protection safeguards the motor against excessive current draw, while short circuit protection helps in detecting and mitigating short circuit faults.

VFDs often incorporate additional protective devices such as line reactors, resistors, and capacitors. Line reactors help in reducing harmonics and provide added protection against power surges and voltage transients. Capacitors and resistors assist in improving motor performance and protecting against voltage spikes and inrush currents.
