ABSTRACT:
A control system, for a motor which may be subjected to stalling loads, provides a non-linear increase in motor current during stalling conditions to maintain rated horsepower. When the maximum transient overload current is reached, this current is maintained to keep the motor torque at a maximum until the motor is stalled. This provides maximum motor torque down to a stalled condition and resists stalling. A limit controller determines the maximum time a particular overload motor current can be maintained and when this time has passed the motor current is reduced to rated current. If the motor should stall completely a further reduction in motor current is made automatically.
