Braking resistor
MS Resistances
Inserting a resistor in the circuit (on stator side for squirrel cage motors and on rotor side for ring type motors ) will help to reduce current appeal, to control torque level and to pilot starting phase duration.
When braking or stopping, a motor needs to purge its kinetic energy. Most simple way is to dissipate this energy into a resistor.
Parameters which will be used for those 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
