The front and rear ends of the middle section housing 2 are respectively against the front end cover 1 and the rear end cover 3. The front end cover 1 and the rear end cover 3 are both provided with a socket 5 for the end of the middle section housing 2 to be inserted. An assembly flange 11 is integrally formed on the front end cover 1. The assembly flange 11 is used to subsequently fix the motor to the equipment to be installed. At least three connecting seats 12 are integrally formed circumferentially on the outer side wall of the front end cover 1. The connecting seats 12 are integrally formed on the outer side wall of the front end cover 1. A threaded hole 121 opening toward the rear end cover 3 is formed on the connecting seat 12, and a fixing seat 31 corresponding to the connecting seat 12 is integrally formed on the outer side wall of the rear end cover 3 in a circumferential direction. A through hole 311 corresponding to the threaded hole 121 is formed on the fixing seat 31, and a stud 6 is provided on the fixing seat 31.
