Summary of the invention
The utility model, for the problems referred to above, provides a kind of double loop permagnetic synchronous motor, locates reliable, stable between this synchronous motor stator iron core and casing.
According to the technical solution of the utility model: a kind of double loop permagnetic synchronous motor, the stator core comprising casing and be arranged in casing and rotor, it is characterized in that: described stator core middle part is fixed with baffle ring, casing inner wall is provided with step, stator core is arranged in casing by baffle ring tight fit, and is located by step; Stator core both ends of the surface are uniform respectively offers some bar-shaped troughs, forms magnetic tooth between adjacent two bar-shaped troughs, an all sheathed stator winding on each described magnetic tooth; Sticky object is filled with between described stator core circumferential surface and casing inner wall.
As further improvement of the utility model, the magnetic tooth at described stator core two ends forms a taper surface respectively, and the described taper surface of every one end is all equipped with a rotor, and the magnet steel that interlaced arrangement polarity is different on each taper surface.
As further improvement of the utility model, the distance between the stator winding on the magnetic tooth of stator core two ends is adjusted by baffle ring.
As further improvement of the utility model, the cross section of described magnetic tooth is fan-shaped, and longitudinal section is trapezoidal.
As further improvement of the utility model, described taper surface is inner conical surface or male cone (strobilus masculinus).
As further improvement of the utility model, described casing two ends connect an end cap respectively, and rotating shaft passes through bearing rotating support on end cap; Described rotor is positioned in rotating shaft.
As further improvement of the utility model, described sticky object is resin.
Technique effect of the present utility model is: the utility model product structure is simple, rationally, between stator core and casing, location is reliable, firm, operationally, relative motion can not occur; Stator core construction in addition in the utility model product is designed to conical surface shape, and coordinates a rotor respectively, forms two " sub-motors " coaxially run, can only with a set of, also can two cover and use, the needs of flexible adaptation user, improve service efficiency further.
