Problems solved by technology

But at that time, it was difficult to manufacture the stator and rotor cores of this type of motor. The milling process not only had low productivity, but also caused uneven tooth slot width indexing, and caused short circuits between the core steel sheets, increasing iron consumption; secondly, when the stator and rotor were running Axial electromagnetic attraction is generated between them, which increases bearing load, shortens life, increases mechanical loss, and reduces efficiency

Abstract

The invention belongs to the technical field of permanent magnetic motors and provides of a one-stator two-rotor axial magnetic field motor stator and case mounting structure which is composed of a grooved annular stator, a stator positioning ring, a motor left case and a motor right case. The mounting structure is characterized in that the grooved annular stator is mounted between the motor leftcase and the motor right case through the stator positioning ring, grooves are formed in two sides of the grooved annular stator, and copper wire windings are placed in the grooves and positioned on two sides of the stator positioning ring. Through several simple structural parts, requirements on axial and radial mounting tolerance and minimum impact on motor performance are meet while the motor annular stator is mounted inside a case safely and reliably.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet motors, and mainly relates to a single-stator double-rotor axial field motor stator and casing installation structure, in particular to a single-stator double-rotor axial field electric motor with a slotted annular stator and casing installation structure. Background technique [0002] In 1821, Faraday invented the first electric motor is a disc motor. Its windings are placed radially along the disc-shaped armature core to generate air-gap flux in the axial direction, so it is also called an axial field motor. But at that time, it was difficult to manufacture the stator and rotor cores of this type of motor. The milling process not only had low productivity, but also caused uneven tooth slot width indexing, and caused short circuits between the core steel sheets, increasing iron consumption; secondly, when the stator and rotor were running Axial electromagnetic attraction is generated be...
