Abstract

The invention provides a vertical type direct-drive permanent magnet synchronous motor. The motor comprises a stator and a rotor, wherein the stator comprises a winding stator core and a case which sleeves the winding stator core; the rotor comprises a rotor core and a rotary shaft penetrating through the rotor core; an upper end cover and a lower end cover are arranged at upper and lower ends ofthe case; the rotary shaft sequentially penetrates through the upper end cover and the lower end cover; a brake device is arranged at the upper end of the rotary shaft and has assisted direction determining and braking functions. The brake device with the simple structure is additionally added and has the assisted direction determining and braking functions, the speed regulating range is large, speed regulation is fast, and operation requirements under complicated geological conditions can be met.

Description

technical field [0001] The invention relates to a vertical direct-drive permanent magnet synchronous motor and belongs to the technical field of electric motors. Background technique [0002] The drive of the traditional top drive drilling system is mainly hydraulic drive. The hydraulic top drive is limited by its working pressure, hydraulic oil working temperature and other factors, with low reliability and poor output performance, which can no longer meet the existing drilling depth requirements. [0003] The direct-drive permanent magnet synchronous motor is a new type of oil drilling equipment, and it is the highest level of mechanical, electrical and oil-integrated oil special equipment. Higher superiority. [0004] Although the direct drive permanent magnet synchronous motor has gradually replaced the traditional hydraulic drive system, the existing permanent magnet motor has a small speed regulation range and relatively slow speed regulation, but it is limited by its...
