Problems solved by technology
[0003] The technical problem to be solved by the present invention is: for the doubly salient pole structure and switch power supply of the existing traditional switched reluctance motor, it has certain disadvantages: one is that the edge flux generated before the stator teeth and rotor teeth overlap causes the current Non-linear; Second, the torque on the rotor of the switched reluctance motor is superimposed by a series of pulse torques, and the resultant torque is not a constant value
These will lead to the inherent torque ripple of the switched reluctance motor, especially the technical problem of large torque ripple when the motor is running at low speed

The invention discloses an axial magnetic flow switch reluctance motor to solve the technical problems that the current nonlinearity is caused by the margin magnet flow produced before a stator tooth and a rotor tooth inside a double-salient-pole structure of a traditional switch reluctance motor are overlapped; the torque on a rotor of the switch reluctance motor is formed by carrying out superposition on a series of pulse torque, and the composite toque is not a constant value. According to the technical scheme, the axial magnetic flow switch reluctance motor comprises a stator magnet yoke, a rotor magnet yoke, a stator unit, a rotor unit, a stator shaft, a fluted disc, a position signal detecting sensor unit and a sensor installing disc. The stator unit is fixed on the stator magnet yoke, the rotor unit is fixed on the rotor magnet yoke, the fluted disc is fixed on the rotor magnet yoke, the stator shaft is connected with the stator magnet yoke, meanwhile, the stator shaft penetrates through the rotor magnet yoke, the fluted disc and the sensor installing disc, and the rotor magnet yoke is connected with the stator shaft through a bearing. The sensor installing disc and the stator shaft are fixed into a whole, and the position signal detecting sensor unit is fixed on the sensor installing disc.
Description
technical field [0001] The invention relates to a novel switched reluctance motor, in particular to an axial flux switched reluctance motor. Background technique [0002] The switched reluctance motor transmission system is a mechatronic AC speed control system, which has many advantages such as simple structure, reliable operation, flexible system control, good speed control performance, and high operating efficiency. It is especially suitable for harsh environments and ultra-high speed applications. Therefore, it is widely used in coal mines, aviation, automobiles and other fields. The power range is from several watts to several megawatts, and the speed range is from several to tens of thousands of revolutions. The traditional switched reluctance motor has a double-salient pole structure. There is neither winding nor permanent magnet on the rotor. Concentrated windings are wound on the stator. The windings on the radially opposite magnetic poles are connected in series to...
