Description
Technical field
The utility model relates to dynamo-electric field, relates in particular to a kind of drive motors, specifically is meant a kind of used for electric vehicle disc type electric machine.
Background technology
Oil shortage and air pollution are two hang-ups of puzzlement automobile industry, and substantial contribution research and development clean energy resource automobile is all dropped in countries in the world, and the research and development of China's electric automobile are in the demonstration operation and the stage is recommended in industrialization.Motor is one of critical piece of electric motor coach, and the effect of motor is that the electric energy with battery stores is converted into the kinetic energy powered vehicle and goes.The drive motors that the electric motor coach that existing market occurs uses has following several kinds substantially: AC induction motor, permagnetic synchronous motor, brush direct current motor, etc.The drawback that these several kinds of motor ubiquity starting currents are big, low-speed performance is poor, efficient is low, failure rate is high, it is more obvious especially to operate in the low speed period, and this shortcoming makes electric motor coach on continual mileage and climbing capacity, receive certain limitation.
What at present driving motor for electric automobile also had that minority uses is switched reluctance machines; The problems referred to above have been improved to a certain extent; But generally adopt radial magnetic field to drive in the existing structure; This has just limited rotor can only be in bore of stator, thereby makes output torque be restricted, and moment of torsion output is still not ideal enough and efficient is lower when low speed.
The utility model content
The technical problem that the utility model will solve is that the used for electric vehicle disc type electric machine that a kind of output torque obviously improves and efficient also promotes to some extent is provided.
The technical solution of the utility model is; Following a kind of used for electric vehicle disc type electric machine is provided; Comprise the double-deck stator of disc type; Stator is provided with armature winding and forms axial magnetic field, is provided with rotor in the bore of stator, the magnetic pole radial of described stator and rotor relatively and the center of magnetic pole on the same face of cylinder.
After adopting above scheme; The utility model used for electric vehicle disc type electric machine operation principle still is similar to switched reluctance machines; Different is, the rotor arrangement of different is switched reluctance machines is concentric with stator in the stator cavity, and rotor rotates down in the effect of the radial magnetic field power that stator coil produces; The utility model then is to utilize the stator armature winding to form axial magnetic field; Thereby on the motor body structure, broken through the structural design of conventional motor, magnetic direction is changed into axial magnetic field by the radial magnetic field of routine, and the magnetic pole radial of stator and rotor relatively and the center of magnetic pole on the same face of cylinder.Because the motor body of the utility model is a flat pattern, owing to improved the axle output torque under the situation that is increased in same magnetic potential energy of root diameter; Electric motor structure is that therefore disc type can make magnetic circuit shorten significantly; The structure that moment of torsion that can be as required and rotating speed are designed to any magnetic logarithm; 96 utmost point double disk structure motors have been designed at present; And can further increase number of poles so that reach bigger moment of torsion, stator is that even number is extremely right, can adjust accordingly according to the requirement to rotating speed; After a pair of magnetic pole energising of stator, generate an electromagnetic field and form the magnetic circuit closure because the active force of the magnetic line of force makes rotor produce displacement; Under the situation that constantly changes magnetic pole conduction time and order, form rotating magnetic field like this and force rotor to rotate synchronously, the conduction time or the voltage that change every utmost point just can realize adjusting rotating speed.Therefore, the switched reluctance machines before the utility model is compared has further promoted the moment of torsion output of motor, and owing to reduced loss, efficiency of motor also gets a promotion.
As preferably, described stator comprises dish and stator lower wall on the stator, is embedded with the magnetic pole of the stator by the silicon steel plate stacking making on the stator on dish and the stator lower wall, and magnetic pole of the stator is provided with around the armature winding of insulated coil skeleton; Described rotor comprises rotor disk and the rotor magnetic pole by silicon steel sheet stack making that is embedded on rotor disk.
As preferably, the silicon steel sheet of making magnetic pole of the stator and rotor magnetic pole is shaped as identical rectangle.
As preferably, the outer ring of dish and stator lower wall is provided with the shell of relative protective cover with the formation motor on the described stator.
As preferably, coaxially on the described rotor disk be fixed with rotating shaft, be fixed with terminal pad on the described stator lower wall.
In sum; The utility model is compared with the conventional motor that present electric automobile uses and had the following advantages: starting torque is big; The axial magnetic field disc-type electric motor can use less starting current to realize bigger detent torque; Test shows that detent torque reaches 150% o'clock of nominal torque, and starting current is merely 30% of rated current; Energy-saving efficiency is high, compares with conventional direct current machine, under equal power output condition, can increase electric motor coach continual mileage 20-30%, when high-speed cruising, can reach 30-40%.
