Problems solved by technology
That is, any conduction or electromagnetic field accompanied by the action of voltage and current will reduce the performance of a certain device, equipment or system, or cause the components or devices adjacent to the motor to suffer electromagnetic interference, which may cause the components or devices adjacent to the motor to malfunction. normal
[0003] In order to reduce electromagnetic interference, electronic components or conductive materials are usually added on the circuit board to reduce electromagnetic interference or increase electromagnetic tolerance, but adding electronic components or conductive materials will affect the characteristics of the motor, and will increase the cost, and the effect is limited

The invention provides an anti-interference structure of a motor stator. The structure comprises a silicon steel sheet group provided with a plurality of silicon steel sheets clamped in an insulatingframe group; a winding group which is wound on the silicon steel sheet group and the insulating frame group; and a connecting piece whch is embedded into the silicon steel sheet group to be in contactwith each silicon steel sheet. Each silicon steel sheet is connected with a grounding end of a circuit board through the connecting piece, so that the contact surface of the connecting piece and thesilicon steel sheet group is increased, and electromagnetic interference is conducted to the grounding end of the circuit board.
Description
technical field [0001] The invention relates to the field of an anti-electromagnetic interference structure, in particular to an anti-interference structure for a motor stator. Background technique [0002] The operation of traditional motors has the problem of Electro Magnetic Compatibility (EMC), that is, the problems of Electromagnetic Interference (EMI) and Electromagnetic Susceptibility (EMS). That is, any conduction or electromagnetic field accompanied by the action of voltage and current will reduce the performance of a certain device, equipment or system, or cause the components or devices adjacent to the motor to suffer electromagnetic interference, which may cause the components or devices adjacent to the motor to malfunction. normal. [0003] In order to reduce electromagnetic interference, electronic components or conductive materials are usually added on the circuit board to reduce electromagnetic interference or increase electromagnetic tolerance, but adding e...
