Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, and provide a kind of turbine inductor type stepping motor, its frequency response is high, make system have high dynamic response, surmounted the step-by-step system limit, moment is large, inertia is little, and magnetic material utilizes rationally.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of turbine inductor type stepping motor, and it comprises:
Stator, mould on described stator has shell and under mould shell, and on mould in shell and be embedded with magnetic conduction sheet in sheet, under mould in shell and be embedded with magnetic conduction sheet under the sheet corresponding with magnetic conduction sheet in sheet, in sheet, under magnetic conduction sheet and sheet corresponding thereto, the magnetic pole of magnetic conduction sheet is oppositely arranged, and on mould shell and under mould in the yoke of shell and be all embedded with kidney-shaped coil;
Rotor assembly, described rotor assembly can be rotated to support on stator, and rotor assembly has disc-shaped multipole magnetization rotor, and disc-shaped multipole magnetization rotor is arranged between magnetic pole that sheet is oppositely arranged between magnetic conduction sheet under magnetic conduction sheet and sheet.
Further in order to better fix disc-shaped multipole magnetization rotor, described rotor assembly also comprises rotating shaft and spring pressuring plate, disc-shaped multipole magnetization rotor is fixedly connected in rotating shaft, one end of spring pressuring plate is fixedly connected with in rotating shaft, the other end of spring pressuring plate by the pressure holding of disc-shaped multipole magnetization rotor in rotating shaft.
After have employed technique scheme, the utility model has following beneficial effect:
1, the utility model have employed the sheet magnetic conduction sheet moulding shell structure, embedded kidney-shaped coil composition stator, and therefore make precision high, processing technology is simple;
2, the utility model can be designed to two-phase or multiphase inductor type stepping motor, and its step angle is 360 °/2pm; Wherein p is rotor pole logarithm, and m is the stator number of phases;
3, the size of step angle depends on rotor pole logarithm, and composite stepper motor of the prior art is subject to the restriction of the number of pole-pairs of stator;
4, stator of the present utility model adopts fewer than composite stepper motor stator coil 1.5 times of Embedded kidney-shaped coil, few 8 times of the electrical steel sheet that the electrical steel sheet that magnetic pole uses uses than composite stepper motor stator.Substantially eliminate stator iron loss, eliminate cogging torque in length and breadth to pulsation, substantially eliminate eddy current loss;
5, the magnetic circuit between stators and rotators is short and straight, and therefore leakage field phenomenon is little.
