Crankcase ventilation systems including integrated sensors and controller

A rotating crankcase ventilation system, comprising:

• a housing comprising an inlet and an outlet;
• a motor comprising a stator and a rotor;
• a shaft, a first end of the shaft coupled to the rotor and configured to rotate in response to rotation of the rotor;
• a filter element coupled to the shaft;
• a sensor configured to measure at least one operating parameter of the rotating crankcase ventilation system;
• a controller operatively coupled to the sensor and the motor, the controller configured to receive the at least one operating parameter and selectively adjust operation of the motor to adjust the rotation of the rotor, and thereby the filter element, based on the at least one operating parameter;
• and
• an audio and/or visual indicator disposed on an outer surface of the housing, wherein:
• the controller is configured to receive signals corresponding to real time values of at least one of a speed of the rotor, a current draw of the motor, a voltage of the motor, a temperature of the motor, and an internal volume of the housing and determine whether the rotating crankcase ventilation system is operating properly based on the received signals;
• and
• the audio and/or visual indicator is configured to indicate whether the rotating crankcase ventilation system is operating properly.

A method of selectively controlling a motor of a rotating crankcase ventilation system, the method comprising:

• receiving, by a controller of the rotating crankcase ventilation system, an operating parameter from a pressure sensor coupled to a housing of the rotating crankcase ventilation system proximate an inlet of the housing;
• determining, by the controller, whether the operating parameter is greater than or equal to a threshold;
• and
• activating, by the controller, the motor responsive to determining the operating parameter is greater than or equal to the threshold.
