FIELD: electrical engineering.
SUBSTANCE: method, device or software implements a technique of overload prevention. This technique involves monitoring of the motor speed, detecting the state of overload based on the average monitored speed and controlling the motor performance according to the detected state of overload.
EFFECT: preventing motor overload, notably in permanent magnet DC motors, such as those used in linear of rotary actuators.
