AI Technical Summary

Technical Problem

In the existing motor structure, adding capacitors can easily interfere with the mating structure of connectors, making it difficult to balance the setting of capacitors and the strength guarantee of connectors. Furthermore, the market demand for miniaturization has resulted in insufficient substrate area, making it difficult to expand to accommodate the addition of new capacitors.

Method used

By providing at least one protrusion near the connector, the position of the capacitor is secured within the opposing range of the circuit board and the flat plate, without increasing the circuit board area, adding capacitors to improve high static voltage performance, and ensuring that the connector does not detach.

Benefits of technology

Without increasing the circuit board area, the number of capacitors can be increased to improve the high static voltage performance of the motor, while ensuring the secure fixing of the connectors near the capacitors to guarantee the stability of the circuit board.
