Detailed Description

The present invention will be further illustrated by the following specific examples, which are carried out on the premise of the technical scheme of the present invention, and it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1 and 2, an electronic control integrated motor comprises a controller PCB (printed circuit board) 1 and a heat dissipation device 2, wherein the controller PCB 1 is fixed on a hub motor 3, the heat dissipation device 2 is arranged on the outer side of the controller PCB 1, and a protective cover is formed above the PCB 1 by glue pouring.

The in-wheel motor 3 is circular, sets up in-wheel motor 3 middle part, and heat abstractor 2 sets up at in-wheel motor 3 edge to there is the clearance with controller PCB board 1 between, set up the installation of clearance for MOS pipe 4. Heat abstractor 2 is the aluminium strip, and a plurality of MOS pipes 4 are fixed on the aluminium strip, and the heat conduction silicone grease of coating between MOS pipe and the aluminium strip, MOS pipe 4 dispels the heat through heat conduction silicone grease and aluminium strip fast, and the pin welding of MOS pipe 4 is on controller PCB board 1.

The controller PCB board 1 is circular and concentric with the hub motor 3, the heat dissipation device 2 is arched, and the shape of the inner edge is consistent with that of the outer edge of the controller PCB board 1. The controller PCB board 1 and the heat dissipation device 2 are riveted or fixed on the hub motor 3 by screws, and a gap exists between the controller PCB board and the motor, so that the motor can dissipate heat conveniently.

The middle position of the controller PCB board 1 contacts with the hub motor 3, and other parts are suspended, so that the circuit board is prevented from being influenced by heat emitted from the inside of the motor.

And the resistor and the capacitor are respectively a chip resistor and a chip capacitor, and are welded in the electronic component of the controller PCB board 1.
