Preferably, the blocking wall is in a circular tube shape. The loop wire is prevented from being wound or touched and damaged with the rotating mechanism (shaft).
Alternatively, a plurality of radially oriented reinforcing ribs are arranged on the wall body of the partition wall on the side where the first inner cavity is located in a surrounding mode.
An alternative scheme is that a wire outlet hole is formed in the annular wall of the second inner cavity. Of course, the wire outlet hole may also be disposed on the cover plate.
An alternative scheme is that the annular wall of the second inner cavity is provided with driving circuit positioning ribs which run axially.
Further, the locating rib is provided with a cover plate mounting screw hole for mounting the cover plate on the motor end cover.
The invention also discloses a motor, which comprises a motor body, a stator, a rotor with double output shafts and the motor end cover, wherein one output shaft of the rotor extends out from a central hole on the partition wall and a shaft hole on the cover plate, and a driving circuit is arranged in a second inner cavity on the cylinder body.
An alternative scheme is that the shaft hole part of the outer end face of the cover plate is provided with a shockproof ring for shock absorption.
According to the invention, the end cover is designed into an integrated end cover, one side is used for fixing the motor, and the other side is used for fixing the driving circuit, and the integrated end cover is adopted, so that the number of parts of a product is reduced, the manufacturing and mounting operation is more convenient, and the mounting working hour cost is reduced. The integrated end cover can flexibly select the cover plate to realize the sharing of the single-double shaft motor end cover, so that the product can better meet the diversified demands of customers, the quality of factory parts is reduced, the product is more standardized, and the management cost is reduced. Meanwhile, an open pore design is adopted between the integrated end cover and the driving circuit board, biaxial correspondence is carried out, the loop of the biaxial high-power motor is realized through the design, and the technical upgrading of the motor is completed.
