Abstract
The utility model provides a built -in permanent -magnet machine, including stator, rotor, permanent magnet and winding, opened the permanent magnetism groove on the rotor, 2 a set of V style of calligraphy evenly distributed on the rotor that are of permanent magnet, the permanent magnet is placed to the inslot. The utility model discloses effectively improve built -in permanent -magnet machine reluctance torque's utilization ratio, improved the power density and the torque density of motor.
Description
Technical field
The utility model relates to a kind of traction electric machine, is specifically related to a kind of interior permanent magnet machines.
Background technology
At present, interior permanent magnet machines is the first-selection of traction electric machine, and it has high torque density, high power density, high starting torque, high efficiency, the features such as speed-regulating range width.But in prior art, interior permanent magnet machines torque density and power density low, the consumption of permanent magnet is large.
Utility model content
The utility model, for above-mentioned problems of the prior art, provides a kind of interior permanent magnet machines, solves torque density and power density in prior art low, the problem that permanent magnet consumption is large.
The technical solution of the utility model is as follows:
A kind of interior permanent magnet machines, comprise stator, rotor, winding and permanent magnet, winding is arranged on stator along rotor outer circle week, and permanent magnet is evenly distributed on rotor.
Described permanent magnet every 2 one group is V-shaped, the opening rotor center of circle dorsad of V-type.
Described permanent magnet one has 8 groups, and 8 groups of permanent magnets are uniformly distributed on rotor.
Angle α between described often group permanent magnet is between 80 ° to 90 °.
The excircle of putting position as far as possible near rotor under the condition meeting mechanical strength of described permanent magnet.
Described rotor is offered permanent magnetism groove, permanent magnet is embedded in permanent magnetism groove.
Described permanent magnet is rectangle.
The utility model has the advantages of as follows:
The utility model effectively utilizes reluctance torque both can improve torque density and power density, can reduce again the consumption of permanent magnet, achieved unexpected technique effect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1-stator, 2-winding, 3-permanent magnet, 4-permanent magnetism groove, 5-rotor.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment
As shown in Figure 1, a kind of interior permanent magnet machines of the present utility model, comprise stator 1, winding 2, permanent magnet 3, permanent magnetism groove 4 and rotor 5, stator sleeve is contained in the outside of rotor, and winding was arranged on stator along rotor outer circle week.Described rotor 5 has 16 permanent magnetism grooves 4, permanent magnetism groove 4 is embedded with rectangular permanent magnet 3.Permanent magnet every 2 one group is V-shaped, and distribute symmetrically and evenly on rotor, V-type opening is oriented the rotor center of circle dorsad, and the angle α often between group permanent magnet is between 80 ° to 90 °, and the putting position of permanent magnet should as far as possible near the cylindrical of rotor under the condition meeting mechanical strength.Such design improves the utilance of reluctance torque, improves power density and the torque density of motor.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection range of the present utility model.
