Abstract: 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.

Abstract: A control method and control system for an agitating mechanism are provided. The control method includes receiving a load current detected by a current detecting apparatus when the agitating mechanism is rotating along a specific direction; determining whether the rotation of the agitating mechanism meets a preset trigger condition based on the load current; and controlling the agitating mechanism to rotate in a direction opposite from the specific direction when the trigger condition is met. The present invention can reduce the possibility of the electrical components of the agitating mechanism being burnt out and prolong the lifespan of the agitating mechanism. The present invention can improve agitation results of the agitating mechanism. At low speed, the agitating mechanism can perform the agitation gently without damaging the texture of the solid food. At high speed, the agitating mechanism can more homogeneously and finely agitate the mushy food with enhanced agitating efficiency.

Abstract: 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.
