Problems solved by technology
The defect of the claw-pole AC synchronous motor is poor directional performance
The structure of the claw-pole AC synchronous motor makes it difficult to achieve directional operation when the frequency is greater than 50 Hz and the rotational speed is greater than 250 revolutions per minute; and when the input voltage fluctuates, there will be a reverse phenomenon
Therefore, it cannot fully meet the requirements for the reliability of the transmission system in the automatic control of some household appliances.

Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] Fig. 1 shows an embodiment of the built-in anti-reverse device of the claw-pole synchronous motor of the present invention. It includes a casing 6 with a plurality of claw poles 3, and a rotor assembly 9 placed in the casing, a skeleton winding is arranged between the casing and the rotor assembly, and the rotor assembly 9 is connected to a rotor output shaft 91 for output power.
[0022] The middle part of the output shaft 91 is provided with a rotor block 1, the outer end of the output shaft 91 is connected with a rotor gear 4, and the rotor gear 4 is meshed with a non-reverse gear 5, and one side of the non-reverse gear 5 is elastically fixed with a non-reverse block 21. The block wheel 2 and the end wall of the casing 6 are fixed with a non-return gear shaft 7 parallel to the output shaft 91, and the non-return gear 5 and the block...

Disclosed an internal holdback device of claw-type synchronous motor, comprises a housing with claws and a rotor component with output shaft. Wherein, a rotor block is mounted inside the output shaft; a rotor wheel is mounted on the outward end of output shaft; the rotor wheel meshes a hold-back wheel which is flexibly fixed on the block wheel with hold-back block; a hold-back wheel shaft inside the housing is in parallel with output shaft; the hold-back wheel and block wheel are mounted and slip on a same hold-back wheel shaft; the top surface of hold-back block touches the side surface of rotor block; a outward protruding cylinder surface is mounted in the center of hold-back wheel; the block wheel has been symmetrical mounted two protruding flexible rings in the form of C whose inner diameter has interference fit to the protruding cylinder surface of hold-back wheel. The advantages of said invention include reasonable design, close structure, better reliability, and wider application range while it reaches the oriented rotation of claw-type synchronous motor.
Description
technical field [0001] The invention relates to the field of an AC micro-motor, in particular to a built-in anti-reverse device of a claw-pole synchronous motor. It is widely used in the transmission and control systems of various household appliances. Background technique [0002] The structure of the claw pole AC synchronous motor includes a casing with claw poles and a rotor assembly placed in the casing, a skeleton winding is arranged between the casing and the rotor assembly, and the rotor assembly is connected to an output shaft. After the alternating current is connected to the coil of the skeleton winding, the output shaft rotates and drives the transmission system under automatic control. The disadvantage of the claw pole AC synchronous motor is poor directional performance. The structure of the claw-pole AC synchronous motor makes it difficult to achieve directional operation when the frequency is greater than 50 Hz and the rotational speed is greater than 250 re...
