Disclosure of Invention

In order to overcome the synchronous machine of present new style timer because of the transition of circle R can't buckle the motor and play the not enough of the effect of fixed motor, the utility model provides a synchronous machine of timer.

The technical proposal of the utility model for solving the technical problem is that: a synchronous motor of a timer comprises a timer shell, a coil assembly and a rotor gear assembly, wherein the coil assembly and the rotor gear assembly are arranged in the timer shell; the outer round angle of the timer shell back to the output gear is evenly and annularly provided with a plurality of square grooves matched with the clamping hooks of the base plate.

Furthermore, the number of the square grooves is four, and the square grooves are uniformly distributed in four directions of the outer corner edge of the timer shell.

The rotor gear assembly sequentially comprises a rotor coil, a rotating shaft, a cladding and an output gear from back to front, the rotor coil is positioned on the rotating shaft, the cladding is also arranged outside the rotor coil, the cladding wraps the front end of the rotor coil positioned on the rotating shaft and is in rotating connection with the rotating shaft, and the output gear is arranged at the foremost end of the rotating shaft; the envelope is made of a non-metallic material.

Further, the timer shell is divided into a shell component and a cover cap installed on the shell component, and the output gear extends out of the cover cap; and the output gear is arranged on the cover cap, the cover shell is fixed, and the rotor gear assembly is arranged.

Furthermore, a wrapping wall extends out of the cover cap and the shell component to divide the timer shell into a stator cabin and a rotor cabin, the coil component is positioned in the stator cabin, and the rotor gear component is positioned in the rotor cabin.

Further, the rotor gear assembly adopts plastic materials except the rotor coil.

The utility model discloses install synchronous machine in the mounting groove on the bed plate when using, then 4 pothooks in the mounting groove outside hook in the square groove on synchronous machine, replace original hook to realize synchronous machine's location on the shell edge.

The beneficial effects of the utility model reside in that: 1. the square groove is arranged at the round corner of the shell to replace the original mounting edge, so that the clamping precision is improved in the circumferential precision. 2. The rotor gear assembly has the advantages that the rotor coil and the gear are integrally designed, the plastic cladding is arranged outside, and the original copper bearing is omitted, so that the quality of the whole fixed motor is reduced, and the cost is reduced.
