Abstract

The invention relates to a synchronous reluctance motor rotor punching sheet, which comprises four uniformly distributed arc grooves arranged at the periphery of a body, four groups of uniformly distributed magnetic barrier mechanisms arranged on the body, and a reinforcing mechanism fixedly connected to the magnetic barrier mechanisms. Through the arrangement of the arc grooves, the arc grooves are air magnetic barriers and play a role of magnetic barriers, one magnetic barrier can be added in a limited space, the quadrature-direct axis magnetic resistance difference is increased to the maximum extent, the output capacity of the synchronous reluctance motor is improved, the symmetry of a magnetic field can be ensured, iron loss is reduced, and the output efficiency is improved through pairwise symmetry of the arc grooves; through the arrangement of the reinforcing mechanisms, the structural strength and the mechanical strength of the rotor can be improved, the maximum rotation speed allowed to operate of the motor is improved, the first magnetic flux barrier and the second magnetic flux barrier are not provided with the reinforcing mechanisms, the quadrature-axis magnetic resistance can be improved, the output capacity of the motor is improved, and the structural stability and reliability of the motor during working are improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a punched sheet of a rotor of a synchronous reluctance motor. Background technique [0002] The synchronous reluctance motor is a new type of AC motor that follows the principle of minimum reluctance path closure and generates magnetic pull (ie, reluctance torque) to drive the motor to rotate through the reluctance changes caused by the rotor at different positions. It has a simple structure and is durable. , high efficiency, wide range of speed regulation, low cost and other advantages. The synchronous reluctance motor is essentially a synchronous motor with reluctance properties. Its operating principle is similar to that of the switched reluctance motor, and it is fundamentally different from the traditional AC and DC motors. The action forms a torque, and following the principle that the magnetic flux is always closed along the path of the least reluctance, the magnetic pull ...
