Abstract
The utility model provides a deceleration-type claw pole permasyn motor, which comprises a support arranged inside an enclosure, a stator coil, a magnetic rotor and a gear reduction mechanism linked with the magnetic rotor. The magnetic rotor is arranged on a central shaft in the center of the enclosure through a pin; the stator coil is sleeved outside the magnetic rotor and is coaxial with the magnetic rotor. The support covers and presses the stator coil and the magnetic rotor. Lower claw poles extend towards the interior of the enclosure. Upper claw poles extend towards the interior of the support. The upper claw poles and the lower claw poles are arranged inside an annular space between the stator coil and the magnetic rotor. Twelve lower claw poles are arranged on the enclosure in a staggered way; eight claw poles are arranged on the support. The lower claw poles on the enclosure are distributed uniformly alternately. The upper claw poles on the left side and the right side of the support are distributed in a centrosymmetrical way. One of the four upper claw poles on one side of the support is lower than the other three upper claw poles. On the premise of not increasing the manufacturing cost of the product, the number of claw poles is designed reasonably; the rotor speed, the dissipation of energy and the running noise are further reduced; the process procedure is very simple.
Description
Technical field
The utility model relates to a kind of speed-reducing type claw poler form permanent magnet synchronous motor.
Background technology
I disclose a kind of speed-reducing type claw poler form permanent magnet synchronous motor in Chinese patent literature CN2599860Y, it comprises a cup-shaped casing, one support, one stator coil, rotor that constitutes by cylinder permanent magnet and one and the gear reduction of rotor interlock, rotor and stator coil are located in the casing and by the support capping, rotor is journaled on the axle of casing central authorities, it is outer and coaxial with rotor that the stator coil sky is enclosed within rotor, inwardly stretch respectively on casing and the support and be provided with the pawl utmost point, in the annulus of the pawl utmost point between stator coil and rotor and be staggered, respectively be provided with eight pawl utmost points on casing and the support.Noise during the motor operation of this eight pawl utmost points is still bigger, and running current makes us not too satisfied still than higher.
