Description
Technical field
The present invention relates to a kind of torque motor manufacturing technology field, specifically a kind of can be at certain angle modelEnclose interior come the finite angle motor of back rotation.
Background technology
At present, on the aerospace craft of many models, make a video recording and all drive camera to enter with angle electrical machineryLine scanning shooting, the quality of angle electrical machinery quality also directly has influence on the quality of pickup quality. Current limited turningThe stator core that angle motor adopts is overall annulus conducting magnet core, and winding is wound around on annulus conducting magnet core, twinesOperation easier around winding is larger, the difficulty that rolls off the production line, and the inside and outside footpath of the flatness of winding profile and winding is also difficult toControl. In the time of motor stator winding embedding, positioning datum is difficult to determine, ensure between motor stator and rotorHigh-axiality and the difficulty of the air gap that turns round uniformly very big, motor torque fluctuation is large. If motor product hasSimilar Problems can have influence on its instructions for use and service life.
Summary of the invention
The technical problem solving
For solving the deficiencies in the prior art, the invention provides a kind of novel finite angle motor, solveOn stator core, be wound around the problem such as winding difficulty and iron core location difficulty.
Technical scheme
The object of the present invention is achieved like this:
After adopting two semicircle iron cores to be wound around respectively winding, be combined into a complete annular stator core;The two ends of semicircle stator core are processed with respectively protruding semicircle and recessed semicircle, are beneficial to two semicircle iron core alignment fixing;The winding being wound around can obtain inside and outside level and smooth surface, and winding one end lead-in wire of two stators is just connected and formedComplete winding. Annular stator core two ends are respectively equipped with locator card, and locator card is stuck on stator core and omitsHigher than winding appearance, stator core is loaded in casing and is located by locator card, stator after embedding, stator and machineThe axiality of shell upper rotor part axis hole is high. Magnet steel is installed on rotor, and rotor is placed in stator, stator and rotor itBetween high, the magnetic gap of coaxial precision large, running air gap is even. What on annular stator core, be wound around is adjacentWinding current opposite direction, makes the limited back rotation of coming in the scope that operates at 30 °～150 ° of rotor.
Beneficial effect
The present invention compared with prior art has the following advantages:
1. the winding of winding is comparatively simple, and assembling, the embedding of stator are convenient;
2. because magnetic gap is large, running air gap is even, motor torque coefficient of variation is less than 2%, meets electricityThe relevant technologies requirement of machine;
The qualification rate of product be improved, service life extend.
