Abstract

The present invention provides a circuit structure, a motor and an electric appliance. The circuit structure is used in the motor, and includes a safety capacitor and a power receiving piece, whereina pin of the safety capacitor is connected to a DC power supply of the motor; the other pin of the safety capacitor is connected to the silicon steel piece of the motor through the power receiving piece. The solution provided by the invention can prevent an EMC interference signal from being transmitted externally, and gradually consumes the EMC interference signal in the form of heat generation,thereby effectively improving the EMC of the motor.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a circuit structure, a motor and electrical appliances. Background technique [0002] The existing EMC improvement methods for electromagnetic compatibility are generally by adding EMC filter devices and optimizing the parameters of EMC filter devices, such as using different specifications of magnetic rings, X capacitors, or common-differential mode inductors according to different frequency bands. However, such improvement measures cannot be used in motors with built-in controllers due to restrictions on the dimensions of EMC filter components and the internal structure of the motor. The EMC generated by the motor needs to be filtered out through a matching motherboard. The cycle is long. Contents of the invention [0003] The main purpose of the present invention is to overcome the defects of the above-mentioned prior art, and provide a circuit structure, motor and electrica...
