Abstract
The utility model relates to a miniature or micro synchronous motor which comprises a rotor module, a front support, a rear support, a front bearing, a rear bearing and a stator module installed between the front and rear supports. The rotor module contains a rotating shaft. The rotating shaft of the rotor module is rotatably arranged on the front and rear supports by means of the front and rear bearings. The front end of the rotating shaft extends out of a central through-hole in the front support. The synchronous motor also comprises a balancing piece. The rear end of the rotating shaft extends out of a central through-hole in the rear support. The balancing piece is fixed to the rear end of the rear end of the rotating shaft which extends out of the central through-hole of the rear support. The synchronous motor provided by the utility model has advantages of smooth start, large starting torque, simple structure and the like.
Description
[
technical field]
The utility model relates to small-sized or micromachine, particularly relates to synchronous machine, especially relates to small-sized or miniature synchronous machine.
[
background technology]
Prior art small-power synchronous machine, is a kind of motor of extensive use in modern household electrical equipment, is mainly used on the household electrical appliance such as hand-held mixer and ice-cream machine, has that easy to assembly, stationarity is good, convenient disassembly and an advantage such as the life-span is long.Referring to Fig. 5, the small-sized or small synchronous motor of prior art comprises rotor assembly, fore-stock 20, after-poppet 30, fore bearing and rear bearing, and is installed on the stator module 10 between described forward and backward support 20,30; Described rotor assembly comprises rotating shaft 41; The rotating shaft 41 of described rotor assembly is held and is arranged on rotationally on described forward and backward support 20,30 by described axle, and the central through hole of these rotating shaft 41 front ends from described fore-stock 20 stretches out; This synchronous machine in use starts and has some setbacks, and starting torsion is less than normal.
[
utility model content]
The technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of smooth and easy, starting torsion small-sized or small synchronous motor larger and simple in structure that starts is provided.
The technical scheme that the utility model solve the technical problem employing is:
A kind of small-sized or small synchronous motor is provided, comprises rotor assembly, fore-stock, after-poppet, fore bearing and rear bearing, and be installed on the stator module between described forward and backward support; Described rotor assembly comprises rotating shaft; The rotating shaft of described rotor assembly is held and is arranged on rotationally on described forward and backward support by described axle, and the central through hole of this rotating shaft front end from described fore-stock stretches out; Described synchronous machine also comprises balance weight; The central through hole of described rotating shaft rear end from described after-poppet stretches out; Described balance weight is fixed on the rear end of the described rotating shaft of stretching out from described after-poppet central through hole.
Described balance weight is cylindrical metal piece.
Compared with the existing technology, the utility model beneficial effect small-sized or small synchronous motor is:
Specially increase balance weight, this balance weight is fixed on the rear end of rotating shaft, and the synchronous machine that increases balance weight can improve torsion and the power while starting, makes synchronous motor starting smooth and easy, and structure is also simple; Therefore the utility model synchronous machine has that starting is smooth and easy, starting torsion is large and advantages of simple structure and simple.
