Rubber permanent magnet accessorial excitation bond-type synchronous reluctance machine

Abstract

The invention relates to an axial sheeted reluctance-synchronous machine, which is characterized in that: a rotor (2) is formed by a rotor spider (21) sheathed tightly on the rotation shaft (3), a rubber permanent magnet sheet (22), and a axial silicon sheet (23); wherein, said rubber permanent magnet sheet (22) and the axial silicon sheet (23) are arranged along the diameter of rotor from inner to outside and bonded layered on the rotor spider (21); said rotor (2) is sheathed by a non-corrodible steel rotor sheath (8) for improving the installment. Said motor has a rubber magnet which is auxiliary to magnetization and abrogates the pin of rotor for fixing axial silicon sheet. It can improve the torque density, the power density, the property and the range of speed in constant power, while the volume and weight are reduced effectively.

Description

technical field [0001] The invention relates to a synchronous reluctance permanent magnet motor, which can also be called an axial lamination synchronous reluctance motor with auxiliary permanent magnet excitation (SR-PM motor for short). The auxiliary excitation material is a rubber magnet, which belongs to the field of new special motors. Background technique [0002] The invention is based on the existing axial lamination synchronous reluctance motor with permanent magnet auxiliary excitation. The existing axial lamination synchronous reluctance motors require relatively large excitation power, resulting in low power factor and low efficiency of the motors, so permanent magnet assisted excitation synchronous reluctance motors appear. However, the existing axial lamination synchronous reluctance motors and axial lamination synchronous reluctance motors with permanent magnet assisted excitation all use pins to fix the axial laminations, resulting in an excessive increase in...

Problems solved by technology

The existing axial laminated synchronous reluctance motors require a large excitation power, resulting in low power factor and low efficiency of the motor, so there is a permanent magnet assisted excitation synchronous reluctance motor

However, the existing axial lamination synchronous reluctance motors and axial lamination synchronous reluctance motors with permanent magnet assisted excitation all use pins to fix the axial laminations, resulting in an excessive increase in the effective magnetic circuit reluctance, and the performance of the motor is better than that without pins. performance drops a lot
