Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 and figure 2 As shown, a high specific power and wide speed regulation servo motor provided by the present invention includes: a casing 11 , a stator 10 , a rotor 20 , an end cover 30 , an elastic pin 40 , a rotary transformer 50 , a clamp 60 and a tail cover 70 . The stator 10 is provided outside the rotor 20 . The input end of the resolver 50 is fixedly connected with the rotating shaft 21 of the rotor 20 , and the rotating shaft 21 drives the input end of the resolver 50 to rotate. The stator 10 and the rotor 20 are arranged inside the casing 11 , and the stator 10 and the casing 11 are fixedly connected by screws 13 . The right end of the end cover 30 is fixedly connected with the left end of the casing 11 by the elastic pin 40, and the right end of the tail cover 70 is fixedly connected with the left end of the...

Abstract

The invention belongs to servo motors, and specifically discloses a high-specific-power and wide-speed regulation servo motor performed under a small-size condition. The high-specific-power and wide-speed regulation servo motor comprises a stator, a rotor, a housing, an end cover, a rotating transformer, a clamp and a tail cover; the stator comprises a stator iron core and a three-phase winding; the stator iron core is of a 9-slot structure; the rotor comprises a rotating shaft, a magnetic steel, a magnetic yoke, a front baffle, a rear baffle, a steel sleeve, a front bearing and a rear bearing; the rotor magnetic steel is of an 8-pole structure and 2.5 in length-diameter ratio. With the adoption of the high-specific-power and wide-speed regulation servo motor, the lightweight and miniaturization structural design of a 500W servo motor within a space having boundary dimension of phi 45*125mm, and the 0.7kW / kg high-specific power and the high-speed-regulation range from 0 to 12000rpm can be achieved.

Description

technical field [0001] The invention belongs to a servo motor, in particular to a servo motor with high specific power and wide speed regulation realized under the condition of small volume. Background technique [0002] Servo technology is an important part of mechatronics. It is widely used in military industry, modern industry and daily life, such as the position swing of launch vehicle engine nozzle, satellite attitude control, missile steering gear attitude control, CNC machine tools, industrial robots and other automation equipment middle. Permanent magnet synchronous servo motor has no commutator, no brush, has excellent low-speed performance, high torque-current ratio, high efficiency, fast dynamic response, simple control, and meets the requirements of high-performance servo drive. It has been widely used in national defense in recent years , industrial and agricultural production and other fields of high servo performance, high reliability small and medium capacit...
