Example Embodiment

[0020] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.

[0021] A hollow motor includes a housing 1, a stator assembly 2, a rotor assembly 3, a rear cover 4, and a front cover 5. The stator assembly 2 includes a coil frame 21 and a magnet 22; the rotor assembly 3 includes a rotor The shaft 31 and the hollow shaft 32 are fixed to the rotor shaft 31 through the hollow shaft 32; the coil bobbin 21 is located between the rotor shaft 31 and the housing 1; the front cover 5 passes through the front The bearing 100 is connected to the front end of the hollow shaft 32; the rear cover 4 is connected to the rear end of the hollow shaft 32 through the rear bearing 101.

[0022] The present invention can directly use the hollow shaft 32 to connect with the transmission structure. Compared with the previous synchronous belt or gear drive mode, the transmission link loss can be reduced, the transmissi...

Abstract

A hollow motor comprises a shell, a stator assembly, a rotor assembly, a rear cover and a front cover; the stator assembly comprises a coil former and magnetic steel; the stator assembly comprises a rotor shaft and a hollow shaft; the hollow shaft passes through and is fixed in the rotor shaft; the coil former is located between the rotor shaft and the shell; the front cover is connected with the front end of the hollow shaft by means of a front bearing; and the rear cover is connected with the rear end of the hollow shaft by means of a rear bearing. The hollow shaft is directly connected with a transmission structure; compared with the present synchronous belt or the gear driving manner, the hollow motor is capable of reducing damages in a transmission process, good in transmission effect, simple in structure, less in quantity of parts and low in cost; the stability of the hollow shaft during transmission is guaranteed by means of the dual bearings, so that the stability of the transmission mechanism during transmission can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a hollow motor. Background technique [0002] At present, the motors generally use synchronous belts or gears to drive the transmission mechanism to rotate, which is easy to cause damage during the transmission process, has a short service life, complex structure, many parts, and light load; and makes the transmission mechanism stable during rotation. Not good, the speed is also unstable, affecting the processing. [0003] At present, most plasma spray guns use a synchronous belt to drive the plasma gun head to rotate, which has the following defects: (1) In terms of rotation, the coaxiality of the rotation cannot be guaranteed, resulting in high heat generation, high noise, and fragile bearings; 2) In terms of transmission, failures such as slipping and jamming caused by the use of O-belts. Contents of the invention [0004] The purpose of the present invention is to overcome...
