Problems solved by technology

In order to make the all-electric servo system achieve high power, it is particularly important to develop super-high-power servo motors. However, the existing servo motors are relatively bulky, have limited working hours, and cannot achieve high specific power, short-term peak overload and other performance indicators. The development of all-electric servo system is limited

Abstract

The invention discloses an ultrahigh-power servomotor, which belongs to the field of servomotors. The ultrahigh-power servomotor comprises a stator and a rotor; the rotor is located in the stator; the central axis of the stator is superposed with the central axis of the rotor; a double-layer winding is wound in stator slots on the stator, so that the electromotive force of the motor is close to the sine-shaped winding; the distribution pattern of the winding on the stator is short-distance distribution; the rotor comprises a rotor shaft and steel magnets; the steel magnets are fixed on the periphery of the rotor shaft; the rotor shaft at which the steel magnets are fixed is of a non-cylindrical structure; the steel magnets are non-uniform-thickness steel magnets; the cross section of each steel magnet is shaped like a reaphook, and the magnetization method is parallel magnetization. The sinusoidality of the electromotive force of the ultrahigh-power servomotor disclosed by the invention is high, and the ultrahigh-power servomotor can realize low inertia, high rotational speed, short-time peak overload and other performance indexes under the condition of high specific power.

Description

technical field [0001] The invention relates to the field of servo motors, in particular to an ultra-high-power servo motor. Background technique [0002] Servo motor is an engine that controls the operation of mechanical components in a servo system, which can realize precise control of speed and position, and is widely used in flight control systems and multi-degree-of-freedom transmission mechanisms. [0003] With the development of servo technology, the all-electric servo system has been paid more and more attention due to its characteristics of miniaturization, light weight and integration. Compared with the traditional servo system, the working time and dynamic performance of the all-electric servo system are lower. be greatly improved. In order to make the all-electric servo system achieve high power, it is particularly important to develop super-high-power servo motors. However, the existing servo motors are relatively bulky, have limited working hours, and cannot a...
