Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Example (b):

referring to fig. 1-4, the present invention provides a technical solution: novel foundry goods motor casing of adjustable installation hole site, including motor casing 1 and the fin 2 of setting at 1 outer wall of motor casing, 1 inner chamber of motor casing is provided with a plurality of heat dissipation archs 3, and heat dissipation archs 3's cross section is trapezoidal, and 3 annular arrays of heat dissipation archs are at 1 inner chamber of motor casing, and 1 lateral wall of motor casing is provided with a plurality of exhaust holes 4, and each exhaust hole 4 of organizing all sets up between two adjacent fins 2.

Specifically, a dust cover 5 for preventing dust from entering the inner cavity of the motor housing 1 through the exhaust hole 4 is further arranged between every two adjacent radiating fins 2. Prevent through setting up dust cover 5 that impurities such as dust from entering into 1 inner chamber of motor casing, cause motor stator and rotor outer wall to adsorb the dust, further influence the radiating problem of stator and rotor.

Specifically, the outer wall of each cooling fin 2 is provided with a cooling groove 6. Through setting up heat dissipation recess 6, increased the area of contact of air with fin 2, improved the radiating effect of air with fin 2.

Specifically, a kidney-shaped hole 7 for adjusting the installation position of the motor housing 1 is formed in the base of the motor housing 1. The length direction of the kidney-shaped hole 7 is perpendicular to the axial direction of the motor shell 1. Through setting up waist shape hole 7, make the screw hole on the motor mounting panel process in advance. The problem that the motor is firstly positioned and then the threaded hole is drilled according to the position of the mounting hole of the motor when the motor is mounted is solved.

Specifically, the base of the motor housing 1 is provided with a positioning pin hole 8. The positioning pin is inserted into the positioning pin hole 8, so that the later-stage motor is prevented from deviating in the operation and the installation position.

One specific application of this embodiment is: a part of heat generated by the running of the motor is transmitted to the motor shell 1 through the heat dissipation bulges 3 with the trapezoidal structures, is transmitted to the heat dissipation fins 2 through the motor shell 1, and exchanges heat with the outside air through the heat dissipation fins 2, so that the temperature of the motor is reduced. The arrangement of the heat dissipation groove 6 on the heat dissipation fin 2 increases the contact area of the heat dissipation fin 2 and air, and improves the heat exchange effect of the heat dissipation fin 2.
