A motor includes a stator, a rotor rotatable relative to the stator, a support member, and a circuit assembly. The circuit assembly includes a plurality of electronic components. The rotor is rotatably mounted to the support member. The stator is received in the rotor. The stator is fixed to the support member, and the support member is at least partially received in an inner side of the stator. A portion of the support member received in the inner side of the stator defines a receiving space, and at least part of the electronic components of the circuit assembly is received in the receiving space of the support member. The support member is partially received in the inner side of the stator, and the circuit assembly is at least partially received in the support member, which makes the motor have a relatively smaller axial size.

Outer rotor motor having support member

An ECU, a control box, and a CMF using the ECU are provided. The control box includes a heat sink and the ECU. The ECU include a support bracket mounted on the heat sink, a power supply board supported by the support bracket, and a signal board stacked over the power supply board and electrically connecting with the power supply board. The support bracket is made of an insulation material. The power supply board carries a plurality of power devices which are in contact with the heat sink for heat dissipation multiple power devices.

ECU, control box and CFM having the same

A motor driving circuit, an application device, and a motor braking method are provided. The driving circuit includes an inverter, a braking unit, and a MCU. The inverter is configured to drive a motor. The braking unit includes a sampling circuit, a discharge circuit, and a switch group. The MCU is connected to the sampling circuit, the discharge circuit, and the switch group, and is configured to control the sampling circuit to detect a voltage across the inverter and obtain a detected value when receiving the emergency signal, compare the detected value to a preset voltage or a preset voltage range, and transmit a control signal to activate the discharge circuit when the detected value is greater than the preset voltage or exceeds the preset voltage range.
