The invention discloses a motor driver. The motor driver comprises a PCB (Printed Circuit Board) and a high-frequency capacitor bypass, the PCB comprises an electric control device; the electric control device is electrically connected with the motor through the high-frequency capacitor bypass; the working frequency of the high-frequency capacitor bypass is different from that of the motor; and the high-frequency capacitance bypass is used for filtering frequency multiplication interference of higher harmonics generated by the electric control device. According to the motor driver, the high-frequency capacitor bypass is arranged in the motor driver, so that frequency multiplication interference of higher harmonics generated by an electric control device can be effectively filtered out, the working frequency of the motor cannot be interfered due to the fact that the working frequency of the high-frequency capacitor bypass is different from that of the motor, and effective operation of the motor can be ensured.

    本发明公开了一种马达驱动器,该马达驱动器包括PCB板和高频电容旁路;所述PCB板包括电控器件;所述电控器件通过所述高频电容旁路与马达电连接;其中,所述高频电容旁路的工作频率与所述马达的工作频率不同;所述高频电容旁路用于滤除所述电控器件产生的高次谐波的倍频干扰。本发明通过在马达驱动器中设置高频电容旁路能够有效滤除电控器件产生的高次谐波的倍频干扰,且由于高频电容旁路的工作频率与马达的工作频率不同,不会对马达的工作频率造成干扰,能够确保马达有效运行。
