Abstract

The invention discloses a hollow large torque servo motor. The servo motor comprises a hollow direct shaft, a first annular step is arranged on the portion, near the front, of the middle of the directshaft, the first annular step is sleeved with a stator core, a stator coil winds on the periphery of the stator core, the outer side of the stator core is provided with an inner rotor core, the innerside of the inner rotor core is bonded with a magnet adjusting magnetic steel through magnetic force, the two ends of the inner rotor core are fixed on a front end cover and a back end cover, and thefront end cover and the back end cover are rotationally supported on the direct shaft; the height-to-width ratio of the stator core is 0.5-3, the width of the inner rotor core is greater than that ofthe stator core, and the length of the first annular step is greater than the width of the stator core. The height-to-width ratio of the stator core is 0.5-3, not only can large enough magnetic forcebe provided, but also the large enough magnetic force transfer area can be provided, the width of the inner rotor core is greater than that of the stator core, it can be ensured that inner rotor coreacquires the large enough magnetic force, and the magnetic leakage is reduced, thereby achieving that the structure is compact, and the large torque can be transferred.

Description

Technical field: [0001] The invention relates to the technical field of motors, in particular to a hollow high-torque servo motor. Background technique: [0002] The structure layout of the existing servo motor is unreasonable, and the occupied space is large. [0003] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. Invention content: [0004] The present invention provides a hollow high-torque servo motor in order to solve the above-mentioned problems in the prior art. [0005] A hollow high-torque servo motor, comprising a direct shaft, the direct shaft is hollow, the middle of the direct shaft is provided with a first annular step in the front, a stator core is sleeved on the first annular step, and the circumference of the stator core is wound There are stator coils, the outer side of the stator core is provided with an inner rotor core, and the inner side of the inner rotor core is magnetically bonded with magnetic ste...
