Abstract

The invention discloses a magnetism gathering passive rotor transverse magnetic flux single-phase motor, and belongs to the transverse magnetic flux motor technology field. The single-phase motor comprises a stator composed of C-shaped stator iron cores and C-shaped permanent magnets, a rotor composed of an L-shaped rotor iron core and a rotor annular magnetic conductive structure, an annular armature winding. The C-shaped stator iron cores and the C-shaped permanent magnets are arranged alternatively in the circumference, and the C-shaped permanent magnets magnetize in the circumferential direction and the magnetization directions of two adjacent C-shaped permanent magnets are opposite. The annular armature winding is wound in the recessed groove formed after the C-shaped stator iron cores and the C-shaped permanent magnets are arranged alternatively. Grooves for insertion of L-shaped rotor iron cores in uniform distribution are formed in the rotor annular magnetic conductive structure. The C-shaped permanent magnets provide an effective magnetomotive force when a main excitation path formed among the rotor, the air gap and the stator goes through the yoke section of the rotor, and the permanent magnet utilization rate is raised.

Description

technical field [0001] The invention discloses a magnetic flux gathering type passive rotor transverse flux single-phase motor, which belongs to the technical field of transverse flux motors. Background technique [0002] Transverse flux permanent magnet motor is a new type of motor proposed by German Professor H.Web in the 1980s. Compared with traditional permanent magnet motors, the magnetic field of this motor is three-dimensionally distributed, and it is in a different plane from the winding, which can take into account The cross-sectional area of ​​the winding and the cross-sectional area of ​​the stator tooth poles increase the torque density of the motor. The prototype motor he proposed and the subsequent modified motors all belong to the surface-mounted permanent magnet structure. The number of permanent magnets is large and the utilization rate is not high. [0003] Rolls-Royce’s bilateral flux-concentrating structure TFM [A. Mitcham, Transverse flux motors for ele...
