Basic Research On Bidirectional Crosslinking Transverse Flux Cylindrical Linear Permanent Magnet Synchronous Motor

The transverse flux configuration motor as a new motor carry out the decoupling of the electrical load and the magnet load.which can greatly improve the motor's thrust density.the low-speed high-thrust motors show a broad application prospects.the motor is valuable.In this paper, a new Bidirectional Crosslinking transverse flux cylindrical linear permanent magnet synchronous motor (BCTFCLPMSM) has been proposed based on transverse flux motor, to solve the the defect of traditional transverse flux motor interval of two adjacent primary core.thereby the of the motor's thrust density has been greatly increased. In this paper, the theoretical study of this motor and get the way of BCTF motor design and produced a prototype for validation.This article firstly analyzed BCTF motor circuit, and get the motor no-load EMF, electromagnetic force, per phase resistance, inductance per phase expression, building a complete model.After analyzing the magnetic circuit model, the parameters of the motor size was analyzed, and get the relationship between thrust densityand the main dimensions of the motor, under the premise of the thrust density ensuring the highest, get a complete BCTF The motor design process.Then use finite element analysis to verify design methods. By ANSOFT12 software, the motor tooth width, pole distance, the thickness of the primary unit of a simulation analysis, the premise of ensuring the thrust density to minimize orientation force and leakage flux motor positioning to get optimal size of the motor.Made a 380W motor,After the analysis of the obtained experimental prototype, the EMF, thrust, resistance, through experimental and simulation results to verify the accuracy of BCTF motor design.
