Abstract
The invention discloses a pole built-in hybrid motor structure. A stator core is a four-pole three-phase induction motor stator core, and is formed by stamping, shearing and laminating a silicon steel sheet; a rotor core is formed by stamping, shearing and laminating a silicon steel sheet, the stamped sheet of a rotor is stamped with four W-shaped grooves for embedding permanent magnets, and aluminum-nickel-cobalt and neodymium-iron-boron permanent magnets are separately inserted into the W-shaped grooves. The pole built-in hybrid motor structure can reduce the influence of quadrature axis armature reaction magnetomotive force generated by load current on the direct axis permanent magnetic field, which is one of the biggest advantages of placing the permanent magnets according to a W-shaped structure in a rotor magnetic circuit.
Description
Technical field
The present invention relates to new-energy automobile manufacturing technology field, particularly relate to the most built-in mixed electric machine structure of one.
Background technology
Along with economic develops rapidly, automobile has become one of important trip mode of people, and electric automobile is because of its distinctive advantage that can reduce air pollution, it has also become the study hotspot of current automotive industry.Electric automobile, under the working conditions such as starting, climbing, needs bigger output torque, and now the travel speed of automobile is slow；In the occasion of some high-speed cruisings, then needing in a bigger scope can the travel speed of invariable power regulation automobile.
Summary of the invention
For solving the problems referred to above present in prior art and practical situation, the present invention provides one the most built-in mixed electric machine structure.Stator core uses 4 pole three phase induction motor stator cores, and described stator core is overrided to form by stalloy punching；Rotor core is overrided to form by stalloy punching, and the punching upper punch of described rotor has 4 W-shaped groove for embedding permanent magnet, inserts aluminum nickel cobalt and Nd-Fe-B permanent magnet respectively in each described W-shaped groove.
Preferably, described stator core tilts a stator tooth away from setting.
Beneficial effect:
The most built-in mixed electric machine structure of one that the embodiment of the present invention provides, can reduce the quadrature axis armature reaction magnetomotive force impact on d-axis permanent magnetic field that load current produces, and this is one of advantage of maximum that in rotor magnetic circuit, permanent magnet is placed by W shape structure.
Detailed description of the invention
Technical solution of the present invention is described in detail below.
The open the most built-in mixed electric machine structure of one of embodiments of the invention.Stator core uses 4 pole three phase induction motor stator cores, and described stator core is overrided to form by stalloy punching；Rotor core is overrided to form by stalloy punching, and the punching upper punch of described rotor has 4 W-shaped groove for embedding permanent magnet, inserts aluminum nickel cobalt and Nd-Fe-B permanent magnet respectively in each described W-shaped groove.
Further, described stator core tilts a stator tooth away from setting.
So, adjust the width of stalloy between the summit of the most lower every two pieces of neodymium iron boron junctions and rotor diameter, can effectively change the magnetic resistance of quadrature axis magnetic circuit.
The rotor of a kind of controllable flux permanent magnet synchronous motor that the embodiment of the present invention provides, have on the premise of not increasing inverter capacity, threephase stator winding is utilized to apply the d-axis armature magnetomotive force of direct-axis current vector pulses generation, the strong and weak of permanent-magnetism synchronous motor permanent magnetic air-gap field is controlled with this, maintained by the permanent magnet on rotor subsequently, i.e. can run in the widest speed adjustable range, and either with or without too much armature loss, also will not sacrifice other performance indications of motor, be weak magnetic wide range speed control truly.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
