[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] See Figures 1 to 5 The permanent magnet brushless motor driver shown in the figure includes: a housing 100, a circuit board 200 and a housing cover 300, wherein the housing cover 300 presses the circuit board 200 into the housing 100.

[0020] In this circuit board 200, a gold finger 210 is provided at the middle of the end away from the outer cover 300; a hole (not shown in the figure) is provided at the bottom of the outer cover 100 for the gold finger 210 to pass through. The gold finger 210 is pressed into the hole and passes through the hole to be inserted into the gold finger slot 410 on the power supply circuit board 400. The power supply circuit board 400 supplies power to the permanent magnet brushless motor driver and transmits control signals. The power supply circuit board 400 is provided with a number of gold finger slots 410, which can be used to connect a number of permanent magnet brushless motor drivers.
