Wide-range weak magnetism at a high speed can be realized, and the permanent-magnet synchronous motor has high low-speed torque capacity, simultaneously meets the requirements on the weak magnetism and the torque capacity, and has fine traction characteristics.
Description
Technical field
The present invention relates to the permanent magnet synchronous motor technical field, specifically the continuous utmost point permanent magnet synchronous motor of a kind of stator band permanent-magnetic clamp.
Background technology
The early 1990s in last century, British scholar proposed the structure original shape of continuous pole, mixed excitation synchronous machine first.Closely during the last ten years, Japan, the U.S. and more domestic scholars compare system research to continuous pole, mixed excitation synchronous machine.Continuously the pole, mixed excitation synchronous machine be a kind of brushless structure, synchronous machine with two-way adjustable magnetic ability, compare with other hybrid exciting synchronous motor, the advantage of pole, mixed excitation synchronous machine is the rotor introducing iron utmost point continuously, excitation magnetic resistance and field ampere-turns are little, weak magnetic efficiency is high, and the DC excitation winding is in stator side, does not need to use brush and slip ring to send into exciting current, non-maintaining, reliability is high.Yet also there are some problems in the pole, mixed excitation synchronous machine continuously: the one, embed the DC excitation winding in the middle of stator core, and cause the mounting process more complicated, produce excitation loss, affect electric efficiency; The 2nd, needing in controller increases the DC excitation circuit, has increased the controller cost; The 3rd, continuous pole hybrid excitation motor need to be set up the magnetic conduction casing, has not only increased the volume and weight of motor, and a little less than motor during magnetic the magnetic conduction casing saturated serious, make motor adjustable magnetic ability descend.
In sum, prior art exists electric machine structure, manufacturing process and control more complicated, and the saturated problem such as serious of magnetic conduction casing during weak magnetic.
Summary of the invention
The object of the present invention is to provide a kind of continuous utmost point permanent magnet synchronous motor of stator band permanent-magnetic clamp that can obtain again good pulling figure when simplifying electric machine structure and manufacturing process, the weak magnetic of wide region when this motor can be realized high speed has again stronger low speed torque ability.
The continuous utmost point permanent magnet synchronous motor of a kind of stator band permanent-magnetic clamp, comprise casing 4, end cap 5, rotor shaft 9, stator core 2, rotor core 8, described casing 4 inwalls are provided with two sections stator cores 2, rotor shaft 9 is provided with two sections rotor cores corresponding with stator core 28, and rotor core 8 is fixed on end cap 5 by rotor shaft 9; Be provided with the permanent magnetic ring 1 of axial charging between described two stator cores 2.
Also be provided with stator polyphase ac winding 3 in described casing 4, stator polyphase ac winding 3 symmetries embed in the groove of stator core 2 one sides.
The described two-stage rotor iron core 8 space electrical degree that axially staggers makes the permanent-magnet pole 6 of one section rotor core 8 and the iron utmost point 7 center lines alignment of another section rotor core 8.
As traction electric machine, the continuous utmost point permanent magnet synchronous motor of stator band permanent-magnetic clamp is when Heng Zhuanjuqu moves, and permanent-magnetic clamp produces by the iron utmost point and increases the magnetic magnetic flux, can adopt the null control strategy of direct-axis current to improve the electromagnetic torque of motor; When Heng Gongshuaiqu moved, the d-axis armature supply played demagnetizing effect to the iron pole field, realizes weak magnetic speed-up.
The advantage of the continuous utmost point permanent magnet synchronous motor of stator band permanent-magnetic clamp of the present invention is: the present invention adopts the DC excitation winding in the continuous pole, mixed excitation synchronous machine of permanent magnetic ring replacement, saved simultaneously its magnetic conduction casing, structure and the manufacturing process of motor are simplified.The weak magnetic of wide region when the present invention both can realize high speed has again stronger low speed torque ability, can take into account simultaneously the requirement of weak magnetic and torque capacity two aspects, has good pulling figure.
