Abstract:
An industrial machine that includes a breaker motor having a rotational speed, a breaker shaft, a sensor, and a controller. The breaker shaft is mechanically coupled to an output of the breaker motor, and the breaker shaft includes a plurality of tools operable to crush a material. The sensor is configured to generate a signal related to a parameter of the breaker motor. The controller is configured to receive the signal from the sensor, determine a value for the parameter of the breaker motor based on the received signal, compare the value for the parameter of the breaker motor to a threshold value, and generate a control signal for modifying the rotational speed of the breaker motor based on the comparison of the value for the parameter of the breaker motor to the threshold value.
