Magnetic ring fixing structure for motor drive controller

The utility model discloses a magnetic ring fixing structure for motor drive controller, including magnetic ring cover body and equipartition in a plurality of wedge fasteners of magnetic ring cover body bottom, the wedge inclined plane of wedge fastener down, the circuit board has a plurality ofly and the corresponding jack of wedge fastener, and in the wedge fastener inserted the jack, magnetic ring cover body passed through wedge fastener and circuit board fixed connection. Perhaps can also set up annular bulge on the terminal, go on further fixedly through the elasticity rubber ring that lies in between annular bulge and the magnetic ring cover body to magnetic ring cover body. Through the utility model discloses, can effectively avoid guarantee that motor drive control ware drive control is reliable and stable, and fixed operations being convenient because the magnetic ring that the influence of adverse circumstances such as humid tropical vibration caused becomes flexible or drops. 本实用新型公开了一种电机驱动控制器的磁环固
