Protects motor insulation
Reduces voltage stress caused by high dv/dt, helping protect motor winding insulation.
dv/dt protection
Long cable runs
EMI reduction
Motor drive output reactors
Connected between variable speed drives and the motor. It limits voltage peaks and high dv/dt effects, especially in applications with long distances between the motor and the drive.
Operating principle
Protects motor winding insulation
Helps protect semiconductor components and motor windings. This reduces the electrical stress on the motor’s winding insulation, allowing the motor to run cooler and more stably.
This helps extend the motor’s service life.
Reduces cable-induced voltage
Limits reflected voltages that can occur in long motor cables.
Reduces electromagnetic effects
Improves the output waveform, helping reduce electromagnetic interference (EMI).
