Abstract
The invention discloses a VC motor, which comprises a rotating shaft positioned in the center, a rotor fixed on the periphery of the rotating shaft, and a stator fixed on the periphery of the rotor, wherein the left and right parts of the stator have arc-shaped structures; air gaps are formed on the arc-shaped structures on the left side and right side of the stator respectively; the outer side edges of the air gaps are provided with permanent magnets; the air gaps are positioned on the outer sides of binding posts on the left and right sides of the stator; the outer sides of the air gaps are provided with 1-2 permanent magnets; and magnetic shunts are formed on the inner sides of the air gaps on the arc-shaped structures of the left side and the right side of the stator respectively. In the VC motor disclosed by the invention, the permanent magnets are moved to the left side and the right side, so that the mutual action of the permanent magnets and an armature slot is reduced, and the torque fluctuation is effectively reduced; and meanwhile, specific to the aim of eliminating negative value torque during zero passage of voltage, the magnetic shunts of the permanent magnets are additionally arranged, so that negative-value torque is effectively eliminated, output power is increased, the motor efficiency is further improved, and the motor efficiency is higher than that of an original PMA motor.
Description
Technical field
The present invention relates to a kind of motor.Particularly relate to a kind of a kind of VC motor that is provided with permanent magnet and can reduces torque ripple.
Background technology
Motor is commonly called as " motor ", is meant according to the law of electromagnetic induction to realize the conversion of electric energy or a kind of calutron of transmission.As shown in Figure 1; Motor normally by the rotating shaft that is in the center 1, be fixed on the rotor 2 on the rotating shaft 1 and be positioned at rotor 2 peripheries by iron core and be wound on the stator 3 that the coil on the iron core constitutes and constitute, be provided with binding post with bottom about described stator 3.The main effect of this motor is to produce driving torque, as the power source of electrical appliance or various machineries.In alternating current machine, when stator winding passes through alternating current, set up armature magnetomotive force, it all has very big influence to motor power conversion and runnability.So the single phase alternating current (A.C.) winding feeds single phase alternating current (A.C.) and produces the pulsating magnetomotive force, this magnetomotive force can be decomposed into two amplitudes equate, rotating speed is opposite rotation magnetomotive force and, thereby in air gap, set up main story and reversing magnetic field and.These two rotating magnetic field cutting rotor conductors, and in rotor conductor, produce induced electromotive force and induced current respectively.
As the PMA motor, as shown in Figure 1, be the permanent magnet 4 of on the stator structure of original motor, packing into, specifically be the upper/lower terminal that permanent magnet 4 is arranged on stator 3, and as shown in Figure 2, be positioned at coil stationary card 5 below.But this set has the motor of permanent magnet 4, because permanent magnet 4 is nearer apart from motor master air gap and armature notch, motor can produce bigger torque ripple and negative value torque when operation, and the stable operation and the power output of motor all had very big adverse effect.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and can reduce torque ripple, a kind of VC motor of elimination negative value torque.
The technical scheme that the present invention adopted is: a kind of VC motor; Include the rotating shaft that is positioned at the center; Be fixed on the rotor and the stator that is positioned at the rotor periphery of rotating shaft periphery; The left and right two-part structure of described stator is an arcuate structure, respectively is formed with the air gap on the arcuate structure of described stator and arranged on left and right sides, and the outer side edges of described air gap is provided with permanent magnet.
Described air gap is positioned at the outside of stator and arranged on left and right sides binding post.
The outside of described air gap respectively is provided with 1～2 permanent magnet.
The inboard that on the arcuate structure of described stator and arranged on left and right sides, is positioned at the air gap also is formed with magnetic shunt respectively.
A kind of VC motor of the present invention moves to the left and right sides with permanent magnet, interacts to reduce permanent magnet and armature slot, thereby effectively weakens torque ripple; Simultaneously, the negative value torque that produces when eliminating voltage zero-cross has been set up permanent magnet magnetic along separate routes, effectively eliminates the negative value torque, has improved power output, and then has improved electric efficiency, and electric efficiency is higher than original PMA motor.
