Abstract

The invention relates to a cylindrical rotor structure optimization method, which comprises the steps that a rotor of a linear switched reluctance motor is symmetrically and equally divided into Nr modules, then the Nr modules are divided into Ng groups, the number of the modules in each group is Nm, the heights of cylinder surfaces in each group are the same, and the cylinder surfaces between adjacent groups have an offset of alpha in the longitudinal direction; the force Fph (z, i) borne by each phase of rotor is calculated according to the longitudinal offset alpha of the rotor on the cylinder surface of the rotor; the propulsive force FSR (z, i) generated by the LSRAs is calculated according to the Fph (z, i); and the fluctuation coefficient fripple is obtained, and then the minimum value of the fluctuation coefficient fripple is obtained. The decoupling of a magnetic circuit and a circuit in geometric design is realized by adopting a transverse magnetic flux structure, and the design is flexible and convenient; the space displacement of a rotor module is optimized, so that the thrust fluctuation of the motor can be effectively reduced; the electromagnetic design, the appearance size and the control strategy of the motor do not need to be changed; therefore, the motor is simple, low in cost, feasible and effective.

Description

technical field [0001] The invention relates to the field of mechanical control, in particular to a cylindrical mover structure optimization method and a transverse magnetic flux linear switch reluctance motor. Background technique [0002] In recent years, linear switched reluctance motors (LSRMs) have gained widespread attention due to their simple structure, low manufacturing cost, high operational reliability, the advantages of being able to operate under various harsh conditions, and low maintenance costs. In addition, the linear switched reluctance motor has excellent starting and speed regulation performance and flexible control strategy. Linear switched reluctance motors include transverse flux switched reluctance motors and longitudinal flux switched reluctance motors. Transverse Flux Switched Reluctance Motor Linear (TFLSRM) utilizes a magnetic circuit perpendicular to the direction of motion and the direction of current flow, this structure makes it very easy to ...
