Abstract
The utility model discloses a permanent-magnet motor stator. The permanent-magnet motor stator is mainly composed of a stator body, wherein the stator body is composed of motor stator windings, a shell and wire frames; the stator body is of a hollow cylinder structure; the wire frames are uniformly distributed on the inner ring of the stator body; a gap between every two wire frames forms a winding groove; one motor stator winding is arranged in the winding groove; the shell is arranged on the outer ring of the stator body; and the shell is integrally formed with the stator body. The permanent-magnet motor stator disclosed by the utility model is an integrally-formed closed structure, so that small bypass notches do not need to be opened in the bottom side of each winding groove, thus reducing and avoiding the generation of structure corner angles, effectively controlling the direction of a magnetic force line, and enhancing the structure strength of the motor stator.
Description
Technical field
The utility model relates to a kind of stator, particularly a kind of permanent magnet motor stator.
Background technology
Existing motor stator is generally the structure of similar hollow cylinder, and sidewall is provided with the coil holder that extends internally within it, and the space between coil holder is winding slot.And the production method of motor stator is first to manufacture the stator piece that strip, a side are coil holder, then bend to cylindric.For crooked convenience, in the centre on the base of winding slot, offer the small gap of stepping down.Due to the restriction of processing method, and the consideration of cost, the size of this small gap of stepping down generally be greater than in actual crooked need allow bit space.Make the bottom of the winding slot of the motor stator after machining still leave this tiny breach, this will form corner angle, and this will cause the diffusion of the magnetic line of force, thereby cause the decrease in efficiency of motor.Due to brake forming, certainly will be from beginning to end, this junction not only forms corner angle, and also can form certain magnetic pole, directly affects the work of motor simultaneously.
Summary of the invention
Order of the present utility model ground is to provide a kind of permanent magnet motor stator in order to solve above-mentioned deficiency, and the bottom of winding slot is without tiny breach, the structure that is one of the forming, and magnetic line of force diffusion is few, and the magnetic field of generation is even, and structural strength is high.
In order to achieve the above object, the utility model provides a kind of permanent magnet motor stator, mainly by stator body, formed, described stator body is comprised of motor stator winding, casing, coil holder, and stator body is hollow cylindrical structure, on the inner ring of stator body, is evenly equipped with coil holder, space between every two coil holders forms winding slot, be provided with motor stator winding in described winding slot, described stator body outer ring is provided with casing, and casing and stator body are formed in one.
Further, be provided with radiating groove between every two winding slots.
Beneficial effect:
1, the direction of the magnetic line of force is reasonable, magnetic field is even;
2, structural strength is high.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
