Abstract

The invention discloses a small-range electromagnetic eccentric magnetic gear pair with a radial magnetic field, and can be widely applied to the field of transmission of industries such as wind power generation, electric vehicles and ship driving. The magnetic gear pair is characterized by consisting of a stator and a planetary rotor, wherein the stator consists of a stator enclosure 4, a stator core 5 with Z1 coil inserting slots and 2p1 stator windings 6 arranged in the slots; the planetary stator consists of a planetary rotor core 16 and 2p2 rotor permanent magnets 17 distributed on the outer circle of the planetary rotor core 16; pole pair numbers p1 and p2 have a small number difference, and are co-prime; the small-range stator is connected with the planetary rotor through an eccentric input shaft 1 on which a bearing IV15 is sleeved to form an eccentric structure; planetary rotor is driven by the eccentric input shaft 1 to revolve about a rotating shaft; a permanent magnetic field of the planetary rotor is coupled with an electromagnetic field of the stator through a radially eccentric air gap; the rotor permanent magnets 17 drive the planetary rotor under the action of the electromagnetic field of the stator to backwards rotate about own axis; and low-speed rotation is output through an output mechanism 9 and an output shaft 11.

Description

technical field

[0001] The present invention is an electromagnetic eccentric magnetic gear pair with less extreme difference in the radial magnetic field. It utilizes electromagnetic magnetic gear transmission technology to realize the mutual conversion of high-speed, small-torque mechanical energy and low-speed, high-torque mechanical energy. It directly replaces the conventional mechanical gear transmission clutch transmission system, and is widely used in wind power generation, hydropower generation, electric vehicles, ship drive and other industrial transmission fields that require direct drive. Background technique

[0002] In many transmission fields of industrial applications, it is often necessary to realize the mutual conversion of low-speed, high-torque mechanical energy and high-speed, low-torque mechanical energy. High-speed mechanical kinetic energy for power generation, electric vehicles and submarine drives need to convert the high-speed mechanical power of th...
