Abstract
A motor assembly configured to receive an external alternating voltage. The motor assembly includes a motor and a circuit assembly. The motor includes a stator and a rotor rotatable about a longitudinal axis. The circuit assembly includes a state detector and a control unit. The state detector is operable to detect whether an external device is receiving the external alternating voltage The control unit is operable to control the motor based on whether the external device is receiving the external alternating voltage.
Claims20
A motor assembly configured to receive an external alternating voltage, the motor assembly comprising:
- a motor including a stator and a rotor rotatable about a longitudinal axis;
- and
- a circuit assembly, the circuit assembly including
- a state detector operable to detect whether an external device is receiving the external alternating voltage, and
- a control unit operable to control the motor based on whether the external device is receiving the external alternating voltage.
A refrigeration system comprising:
- a line input;
- a neutral input;
- a compressor electrically coupled to the line input and the neutral input;
- a motor including
- a stator,
- a rotor,
- a state detector electrically coupled to the line input, the neutral input, and the compressor, the state detector configured to output
- a first signal indicating that the compressor is electrically coupled to the line input and the neutral input, and
- a second signal indicating that the compressor is not electrically coupled to the line input, and
- a control unit operable to
- receive at least one selected from the group consisting of the first signal and the second signal, and
- control the motor based on the received signal.
