M.S. RESISTANCES

Motor Control Resistor

When starting, an electrical motor has a huge current demand.Inserting a resistor in the circuit (on stator side for squirrel cage motors and on rotor side for ring type motors) will help reduce current appeal, control torque level and pilot starting phase duration.

Parameters that will be used for these resistors are:

• Stator or rotor electrical data,
• Motor power,
• Number of starting or braking steps,
• Rated starting torque,
• Starting or braking duration,
• Starting or braking motor load or inertia
