Description
Technical field
The present invention is a kind of capacitor split-pole phase-splitting starting dual-purpose electric machine stator, is related to a kind of stator of motor, special
It is not to be related to a kind of dual-purpose electric machine stator that capacitor split-phase, split-pole phase-splitting starting and operation can be respectively adopted.
Background technique
Monopole asynchronous motor is divided into split-phase type (or phase shift) and shaded-pole two types according to stator structure.Point
Phase formula monopole asynchronous motor has auxiliary winding and Working winding in the stator, and auxiliary winding is spatially differed with Working winding
90 degree of electrical angles make electric current phase of the current phase of auxiliary winding with Working winding using capacitor or the phase separation of resistance
Phase difference is about 90 degree, and auxiliary winding and Working winding collective effect generate stator rotating excitation field.The single-phase asynchronous electricity of split-phase type
Motivation stator structure is complicated, and common split-phase type single-phase asynchronous electromotor stator structure is using distributed winding, and distributed winding is not
Suitable for micromotor.Capacitor split-phase monopole asynchronous motor has the advantages that high-efficient, power factor (PF) is high.
Shadedpole motor is divided into salient pole type shaded-pole motor and hidden pole type shaded-pole motor according to stator structure.Salient pole
The split-pole winding of formula shaded-pole motor is the short-circuit copper ring of one to two circle, and the split-pole winding of hidden pole type shaded-pole motor is winding both ends
The distributed winding being shorted together.Hidden pole type shaded-pole motor and the capacitor split-phase asynchronous motor phase for being all distributed winding
Than without advantage in terms of performance and cost.Although hidden pole type shaded-pole motor performance is better than salient pole type shaded-pole motor performance,
The few application cases of hidden pole type shaded-pole motor, salient pole type shaded-pole motor is because its structure is simple, at low cost, in miniature electric
Machine application field still occupies a tiny space.The main winding of shadedpole motor generates main flux, and a part of main flux passes through cover
Pole winding (short-circuit copper ring or hidden pole type split-pole winding) and the induction that 90 degree of lag in a phase is generated in split-pole winding
Electric current, the split-pole area resultant flux which generates also lags behind main flux in phase, to generate stator rotary magnetic
?.
Space angle between the main winding field axis and split-pole winding field axis of simple shaded pole motor is less than nine
Ten degree, the ratio of split-pole area magnet pole widths and entire stator magnetic pole width is known as split-pole degree.Under the premise of other parameters are constant, cover
Extremely smaller, for winding space angle closer to 90 degree, the ovality of rotating excitation field is smaller.But split-pole area resultant flux be by
Main flux induction generates, and split-pole degree is smaller, and split-pole area resultant flux is smaller, and the ovality of rotating excitation field is bigger.In order to obtain
Big output torque reduces the ovality of rotating excitation field, it should keep the main flux in main pole area equal with split-pole area resultant flux
Or it is close.The structure of simple shaded pole motor determines the contradiction between its split-pole degree and rotating excitation field ovality, makes it
Be unable to satisfy the technical solution of following raising output torques: i.e. either salient pole type shaded-pole motor or hidden pole type split-pole is electric
Motivation, under the premise of not changing winding magnetic pole space angle, increasing the magnetic pole of the stator sectional area that split-pole winding covers can increase
Covering polar region resultant flux, finally improves output torque.
Split-pole split-phase monopole asynchronous motor efficiency specific capacitance split-phase monopole asynchronous motor low efficiency, but split-pole is electronic
Machine overload even stall when complete machine curent change it is little, the advantages of being not susceptible to failure, is that its is exclusive, therefore in safety
Shaded-pole motor can would generally be selected in demanding environment.Compared with capacitor split-phase monopole asynchronous motor, split-pole split-phase list
The output mechanical property of phase asynchronous motor is softer, and revolutional slip is larger.If a motor is provided simultaneously with capacitor split-phase, split-pole point
The function of phase, then the motor can switch between different operational modes, provide two kinds of different output mechanical properties and revolving speed
Driving force.In addition, assembling split-pole winding or auxiliary winding respectively using identical stator core specification, have it respectively
Split-pole split-phase, capacitor split-phase operational mode can reduce entreprise cost under the premise of providing two kinds of motor products.
