Publication number: 20160341202Abstract: An electric pump has a pump body, a pump magnet received in the pump body, an impeller received in the pump body and fixed to the pump magnet, and a disc type electric motor. The electric motor includes a stator, disc type coils fixed to a surface of the stator, a rotor rotatably positioned above the coils, and a circuit board electrically connected to the coils. The rotor has a rotor magnet positioned beneath the pump body and magnetically coupled to the pump magnet. When the coils are energized, an axial magnetic field is generated to drive the rotor and, through the magnetic coupling between the rotor magnet and the pump magnet, rotate the impeller.Type: ApplicationFiled: May 18, 2016Publication date: November 24, 2016Inventors: Jie CHAI, Ching Hang LEUNG, Kwong Yip POON, Chun Kei YU, Wei Feng YUAN, Tao ZHANG, San Yuan XIAO

Publication number: 20160341203Abstract: In an aspect, a clutched device is provided, and includes an input member, an output member, a one-way clutch that can operatively connect the input member to the output member, and a motor including a stator and a rotor. The rotor is connected for rotation with a portion of the one-way clutch. The stator is operable to apply a first magnetic driving force to cause movement of the portion of the one-way clutch in a first rotational direction to increase a force of engagement between the input and output members. The stator is operable to apply a second magnetic driving force to cause movement of the portion of the one-way clutch to disengage the input and output members from each other.Type: ApplicationFiled: January 12, 2015Publication date: November 24, 2016Inventors: Scott D. Parsons, Gary J. Spicer, Roman Tracz
