Motor assembly with integrated on/off detection with speed profile operation

摘要

A motor assembly coupled to an external alternating voltage input, the motor assembly comprising a motor including a stator and a rotor rotatable about a longitudinal axis. The motor assembly further includes a circuit assembly, the circuit assembly having a state detector operable to detect the state of the external alternating voltage input and a control unit operable to control the motor based on the state of the external alternating voltage input detected by the state detector. The motor assembly also includes a housing substantially encasing the motor, and the circuit assembly.

1. 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 including a line input, a neutral input, and a discrete high voltage input, the state detector operable to detect whether an external device is receiving the external alternating voltage based on a first comparison of the line input to the discrete high voltage input and a second comparison of the neutral input to the discrete high voltage input, anda control unit operable to control the motor based on whether the external device is receiving the external alternating voltage; wherein the state detector generates a first logic output signal and a second logic output signal received by the control unit, the first logic output signal indicating whether the external alternating voltage is equal to a neutral connection and the second logic output signal indicating whether the external alternating voltage is equal to a line connection.
