2. The structure of the motor is simple, there is no winding of any form on the rotor; there are only simple concentrated windings on the stator, the ends are short, and there is no interphase jumper
It can be seen from the working principle that the torque generated on the rotor of the S switched reluctance motor is superimposed by a series of pulse torques. Due to the influence of the double salient pole structure and the nonlinear saturation of the magnetic circuit, the resultant torque is not a constant torque. , while there is a certain harmonic component, which affects the low-speed operation performance of the SR motor

Embodiment Construction
[0014] figure 1 It is an in-line motor 017 with double-helical external tooth pole halbach array stator components. The stator is two external spiral stator pole cores 0271 arranged opposite to each other along the circumference, and the outer spiral stator pole core 0271 is connected by a ring yoke iron 0273 The outer helical coil 0272, the ring-shaped yoke iron 0273 between the tooth poles is sleeved with the yoke iron coil 0274 to form a double outer helical halbach array stator tooth pole component 0279, which is arranged in a straight line along the direction of the rotating shaft to form a double outer helical halbach array stator 027. The mover tooth pole 037 is set inside, and the mover tooth pole is 6 sheet-like double-helix mover units spirally arranged to form an overall double-helix mover.
[0015] When in use, each component constitutes a halbach array to generate a magnetic field between two tooth poles. Assuming only one layer of magnetic conduction, the magneti...

The invention discloses a double-spiral external tooth pole halbach array stator member linear-arrangement motor (017). A stator is two external spiral stator tooth pole iron cores (0271) which are oppositely set along the periphery, and the external spiral stator tooth pole iron cores (0271) are connected through annular yokes (0273) and are sleeved by external spiral coils (0272). The annular yokes (0273) between the tooth poles are sleeved by yoke coils (0274), thereby forming double-spiral external tooth pole halbach array stator members (0279). The double-spiral external tooth pole halbach array stator members (0279) are linearly arranged in the direction of a rotating shaft, thereby forming a double-spiral external halbach array stator (027). The interior of the double-spiral external halbach array stator (027) is sleeved by rotor tooth poles (037), and the rotor tooth poles (037) are six sheet-shaped spiral rotor units, wherein the six sheet-shaped spiral rotor units are spirally arranged to form an integrated double-spiral rotor. In use, each member forms a halbach array, thereby generating a magnetic field between two tooth poles. Supposing that there is only one magnetic-conduction layer, a magnetic force line passes through an air gap and a real rotor tooth pole unit, thereby forming a loop.
