Abstract

The invention discloses a concentrated winding transverse flux permanent magnet synchronous motor, which comprises stator E-shaped teeth, a stator yoke part, a stator winding, rotor magnetic steel anda rotor yoke part, the stator E-shaped teeth comprise three teeth and two grooves, and the three teeth face the air gap and are axially arranged; the stator winding is wound on the middle teeth of the stator E-shaped teeth and fills the two grooves to form a concentrated winding coil, and the winding directions of the coils of the two adjacent stator E-shaped teeth are opposite; the stator yoke part wraps the exposed windings of the two adjacent stator E-shaped teeth; each pole of rotor magnetic steel is formed by axially arranging three pieces of magnetic steel with alternate N poles and S poles, and the three pieces of magnetic steel are respectively aligned with three teeth of the E-shaped teeth of the stator; the polarities of the rotor magnetic steels of two adjacent poles are opposite; the rotor yoke part provides a magnetic flux loop and comprises a radial magnetic flux direction and a transverse magnetic flux direction. According to the invention, the utilization rate of the stator winding can be greatly improved.

Description

technical field

[0001] The invention belongs to the technical field of permanent magnet motors, and more specifically relates to a permanent magnet synchronous motor with concentrated winding transverse flux. Background technique

[0002] Since the Industrial Revolution, human society has entered the electrical age from the steam age. Machine production has gradually replaced human labor. Form motors are the most widely used electrical equipment in industrial and agricultural production and civil industries. The annual electricity consumption of various motors accounts for about 70% of my country's total power generation. Various new energy sources such as photovoltaics, wind power, and nuclear power also use electric energy as a secondary energy source, so higher requirements are placed on the development of motors.

[0003] my country's economy is huge, and under the background of the energy crisis gradually restricting economic development, power shortage will be the norm...
