Embodiment Construction
[0021] In order to describe the present invention in detail, the specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.
[0022] The invention provides a stator core of a claw pole permanent magnet motor using a mixed structure of soft magnetic composite material and silicon steel. Taking an inner rotor claw pole permanent magnet motor as an example, the proposed core structure is aimed at the outer stator core of the motor. The motor includes a rotor core 4, a stator core, a permanent magnet 5, and an armature winding 3, wherein the materials and structures of the rotor core, the permanent magnet, and the armature winding are similar to those of a common claw pole permanent magnet motor, and the armature winding is arranged on The stator core is wrapped by stator claw poles 1 and stator yoke 2; permanent magnets are arranged on the side of the rotor core opposite to the stator core, and there is a...

The invention relates to a stator core of a claw pole motor and a motor assembly using the stator core, the stator core comprises a stator yoke made of rolled silicon steel and a plurality of stator claw poles made of soft magnetic composite materials, and the plurality of stator claw poles are alternately fixed on two sides of the stator yoke. The tail ends of a pair of alternately distributed stator claw poles respectively correspond to a pair of permanent magnets with opposite polarities, magnetic induction lines of the permanent magnets enter the stator claw poles from the lower parts of the stator claw poles opposite to the permanent magnets, are shunted to a plurality of layers of silicon steel sheets of a stator yoke part through the stator claw poles, flow in parallel in each lamination of the stator yoke part, penetrate through the stator claw poles on the other side along the laminations and return to the adjacent permanent magnets after passing through the whole stator claw poles; the magnetic induction lines flow through each lamination of the stator yoke and almost do not penetrate through the insulating layer in the middle, that is, no eddy current is generated. The stator core structure can ensure smooth passage of a magnetic circuit, can also ensure low eddy current loss, and meets the requirement of three-dimensional magnetic flux characteristics.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a stator core of a claw-pole motor which adopts soft magnetic composite materials and rolled silicon steel sheets. The stator core includes a stator yoke made of rolled silicon steel and a stator claw pole made of soft magnetic composite material. Background technique [0002] The claw pole motor is a kind of transverse flux motor. Compared with the radial flux motor, it has the advantages of high power density and torque density; and the armature winding is simple, and the winding shape is distributed inside the motor in a ring shape. No end windings. Compared with electric excitation claw pole motors, claw pole permanent magnet motors do not require excitation windings, reduce brushes and commutator devices, and are easy to maintain; since no excitation current is required, it is beneficial to improve motor efficiency. The permanent magnets of the claw pole permanent magnet mo...
