Abstract
The present invention relates to a kind of three-phase stepper motor, including stator, rotor and coil, described stator is provided with 12 stator poles, and described coil across two stator poles modes being at least wound on stator.Compared with prior art, the present invention has the advantages that significantly to lift torque.
Description
Technical field
The present invention relates to a kind of motor, more particularly, to a kind of three-phase stepper motor.
Background technology
Stepper motor is the opened loop control motor that electric impulse signal is changed into angular displacement or displacement of the lines.Stepper motor
Species, divides according to the number of phases, is generally divided into two-phase, three-phase and five phases.Three-phase stepper motor is compared preferably fortune
Row stationarity, drive control is relatively easy to implement, there is good application prospect.
Existing three-phase stepper motor, stator winding mode is wound on stator monopole for coil, principle such as Fig. 1 and Tu
Shown in 2, current three-phase stepper motor, compared to widely used two-phase stepping motor, motor torque is small,
Many application scenarios, are limited by torque, can not be applied upper.
The content of the invention
The purpose of the present invention is exactly to provide one kind for the defect for overcoming above-mentioned prior art to exist significantly to be lifted
The three-phase stepper motor of torque.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of three-phase stepper motor, including stator, rotor and coil, described stator are provided with 12 stator poles,
Characterized in that, described coil across two stator poles modes being at least wound on stator.
Preferably, described coil is wound on stator with across two stator poles modes.
Preferably, described coil is wound on stator with across three stator poles modes.
Preferably, magnetic stripe is inlayed in described stator poles teeth groove.
Preferably, described magnetic stripe is provided with 2-4.
Preferably, described magnetic stripe is provided with 3.
Compared with prior art, the present invention has advantages below：
1st, torque is significantly lifted, from the point of view of electric current number of ampere turns M curve data, across the pole coiling edge magnetic stripe of stator
Motor, torque has more than 90% lifting, greatly improves the not enough problem of torque；
2nd, from the point of view of PULL OUT (involving torque) curve data, across the level coiling edge magnetic stripe motor of stator,
In the range of 500RPM, output torque has and is significantly lifted during motor operation.Stator is selected in 200RPM
It is better across 3 pole coiling edge magnetic stripes；From stator across 2 pole coiling edge magnetic stripes in 200~500RPM,
It is better.

Across the pole coiling of son lifts the scheme of torque, and magnetic stripe 113 is inlayed in described stator poles teeth groove.Described magnetic stripe is provided with
2-4, preferably described magnetic stripe is provided with 3, so preferably ensure that the significantly lifting of torque.
Embodiment 2
Described coil is wound on stator with across three stator poles modes, and remaining is with embodiment 1.
As shown in fig. 7, being the number of ampere turns M curve of not Co-wound coil：Reflect different input currents, motor power output
The ability of square, from the point of view of electric current number of ampere turns M curve data, the motor of magnetic stripe is inlayed in across the pole coiling of stator, and torque has
More than 90% lifting.
As shown in figure 8, being PULL OUT (involving torque) curve of not Co-wound coil：When friction speed is run
Torque output, from the point of view of PULL OUT (involving torque) curve data, stator across level coiling edge magnetic stripe electricity
Machine, in the range of 500RPM, output torque has and is significantly lifted during motor operation.
The above, specific embodiment only of the invention, but protection scope of the present invention is not limited thereto,
Any one skilled in the art the invention discloses technical scope in, can readily occur in various equivalent
Modification or replacement, these modification or replacement should all be included within the scope of the present invention.Therefore, the present invention
Protection domain should be defined by scope of the claims.
