Description
Technical field
This utility model relates to brshless DC motor, a kind of high-power, small size, high efficiency brushless direct-current lifting
Motor.
Background technology
The driver that brshless DC motor is made up of motor body and electronic devices and components forms, and is a kind of typical dynamo-electric one
Body product.Brshless DC motor refers to the direct current generator of brushless and diverter.
Having diverter on the rotor of common DC motor, the end of a thread of armature rotor winding accesses in diverter, embedding in stator
Permanent magnet, brush is had to be fixed on stator.Rely on brush and contact the electricity that source current is transmitted to by brush to be rotated with diverter
In pivot winding.
Abrasion and the gradually accumulation of abrasion powder between diverter and brush will be stained diverter, it is necessary to routine cleaning
And replacing brush, the electromagnetic wave that commutation spark produces can disturb other neighbouring electronic equipment, therefore brushed DC motor
Life-span is short, has electromagnetic wave to produce.
Between the stator and rotor of brshless DC motor in addition to bearing, there is no other contact wear component, rely on electronic power to open
Closing switching and the flow direction, i.e. electronic commutation controlling each phase winding electric current in stator armature respectively, therefore brshless DC motor is excellent
Point is non-maintaining, life-span length and does not produce electromagnetism clutter.
But, high-power, the rotor of small size motor, constitute for high energy product rare-earth permanent magnet, the strong magnetic of many magnetic poles turns
Son, when high rotating speed, produces serious magnetic hysteresis eddy-current loss in stator core, and iron loss makes that the motor feels hot, efficiency reduces, therefore
Stator core stamping sheet must possess sufficiently large insulation resistance accordingly, could effectively reduce iron loss.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of punching electrical insulation capability each other
Excellent brshless DC motor.
The purpose of this utility model is achieved through the following technical solutions: one is high-power, small size, high efficiency are brushless directly
Flowing bridge motor, it includes casing, and the front end of casing is provided with drive end bearing bracket, and the rear end of casing is provided with rear end cap, in casing
Being additionally provided with stator assembly and rotor assembly, described stator module is made up of stator core and armature winding, and armature winding is wound around
On stator core, described stator core includes multi-disc punching, and in punching, punching press is provided with multiple arch boss, arch boss
Female ends formed long kidney-shaped hole, the arch boss of a rear punching snaps in the long kidney-shaped hole of previous punching, in described punching
It is further opened with the through hole that rotor assembly passes through.
Described punching has the first insulating barrier and the second insulating barrier of vacuum coating that roller coating processes, and described first is exhausted
Edge layer is positioned at the surface of the second insulating barrier
Described arch boss is three, and is evenly distributed on same circumference.
This utility model has the advantage that brushless direct-current bridge motor of the present utility model, punching roller coating process the
The second insulating barrier that one insulating barrier and vacuum coating process, the mix insulation layer of two kinds of technique making makes than traditional single technique
Insulation between plates resistance improve 40%, because of punching sheet surface be technique for vacuum coating process the second insulating barrier, uniform coating thickness,
Fine and close free of pinholes, transparent unstressed, without auxiliary agent, do not damage punching, the electrical insulating property having excellence and protective, each punching it
Between, is connected by the realization of linking closely with long kidney-shaped hole of self arch boss, its compact conformation, and laminates technique simply, easy to operate,
So that bridge motor meets high-power, small size, high efficiency requirement.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described, protection domain of the present utility model be not limited to
Lower described:
As shown in Fig. 1 ~ Fig. 3, a kind of high-power, small size, high efficiency brushless direct-current bridge motor, it includes casing 16,
The front end of casing 16 is provided with drive end bearing bracket 15, and the rear end of casing 16 is provided with rear end cap 17, is additionally provided with stator in casing 16
Assembly and rotor assembly, described stator module is made up of stator core and armature winding, and armature winding is wrapped on stator core,
Described stator core includes multi-disc punching 11, and in punching 11, punching press is provided with multiple arch boss 12, in the present embodiment, institute
The arch boss 12 stated is three, and is evenly distributed on same circumference, and the female ends of arch boss 12 forms long kidney-shaped hole 13,
The arch boss 12 of a rear punching 11 snaps in the long kidney-shaped hole 13 of previous punching, between arch boss 12 and long kidney-shaped hole 13
Cooperation use interference fit, its magnitude of interference is 0.03 ~ 0.06mm, so that all of punching is by arch boss 12 and waist
It is an entirety that shape elongated hole 13 links closely, and has good steadiness, and described punching 11 has the first insulation that roller coating processes
Layer and the second insulating barrier of vacuum coating, the first described insulating barrier is positioned at the surface of the second insulating barrier, thus effectively reduces
Iron loss, improves efficiency, described punching 11 is further opened with the through hole 14 that rotor assembly passes through.
