Abstract

The invention, which belongs to the technical field of the motor, provides a motor comprising a case, a main shaft, end covers, a bearing seat, moving parts, a bearing and control parts. The moving parts include a permanent-magnet rotor and a stator winding. The control parts include a rotating transformer and a junction box. A main shaft is arranged in the hollow space of the case coaxially. The moving parts are arranged between the case and the main shaft. The end covers are arranged at the two ends of the case; an oil supply hole is formed in the front end cover and is communicated with a channel, thereby realizing effects of lubrication and cooling. A framework oil seal is arranged between the main shaft and the bearing seat so as to realize a better sealing effect. Oil control rings are arranged between the main shaft and the bearing seat and between the main shaft and the front end cover; light surfaces of the oil control rings correspond to oil storage grooves; second oil outlets are formed in the oil storage grooves; and thus a cooling effect is realized. Third oil outlets are formed in the stator winding, so that a liquid discharging effect is good. Besides, a tail-end inclined oil channel is arranged on the rear cover, so that safety oil discharging is realized and the security is high. And with the rotating transformer, angle and position sensing and measuring are realized and the operation becomes stable.

Description

technical field

[0001] The invention relates to the technical field of motors, in particular to a motor. Background technique

[0002] With the development of electric energy, electric energy plays an important role in people's production and life. From a small perspective, most equipment needs to be driven. At present, the most important driving method is to use motor drive. Therefore, the motor's Research has come into the spotlight.

[0003] However, the motors currently on the market basically use rolling bearings as an effective way to reduce friction, and the lubrication effect on the bearings is not ideal, requiring long-term and continuous manual adding of lubricating oil, which brings a certain workload to the user, which is not suitable for machines. The modern design concept, and the radial load capacity of the rolling bearing is poor; and the motor shell is set into a fin shape as the main way of heat dissipation, which is difficult to process, and the heat diss...
