Abstract

A disc type iron core-free magnetic flux modulation motor is disclosed and relates to the field of disc type motors. The disc type iron core-free magnetic flux modulation motor can help solve a problem that a conventional disc type magnetic flux modulation motor is high in loss, magnetic flux modulation blocks are poor in mechanical properties, stator iron cores are large in weight and the conventional disc type magnetic flux modulation motor is complex in structure. In the disc type iron core-free magnetic flux modulation motor, N stators and N+1 rotor round discs are arranged in a staggered manner, air gaps are arranged between the stators and the rotor round discs, each stator comprises a winding and two non-magnetic-conductive armature discs, the annular winding is packaged between the two non-magnetic-conductive armature discs, Ns grooves are arranged on each non-magnetic-conductive armature disc, the Ns groove are uniformly arranged along the circumferential direction of the non-magnetic-conductive armature disc, and one magnetic flux modulation block is arranged in each groove; a side face, positioned close to the stator, of each of first and (N+1)th rotor round discs is provided with 2P2 magnetic steel parts; each of two side faces of second to Nth rotor round discs is provided with 2P2 magnetic steel parts; P2 indicates a number of pole pairs on one side face of each rotor round disc; a number of pole pairs in an magnetic field generated via power-on of each winding is indicated as P1, and P1 plus P2 is Ns. The disc type iron core-free magnetic flux modulation motor is mainly applied to power transmission.

Description

technical field [0001] The invention relates to the field of disc motors. Background technique [0002] In recent years, with the continuous development of my country's industrial level, there are higher requirements for power transmission in industry. As a direct drive system that replaces traditional complex transmission, it is gradually attracting people's attention. In the power transmission of traditional gears and motors, not only the system is bulky and the reliability is low, but the wear of the gears brings problems such as friction loss, regular maintenance, and large vibration and noise. Magnetic gear is a kind of gear that relies on magnetic transmission. It not only eliminates the traditional mechanical friction loss, but also greatly reduces vibration and noise because there is no contact between the gears. It requires no maintenance and has high reliability. Based on the principle of magnetic gears, a series of magnetic flux modulation motors with reliable st...
