Abstract

The invention discloses an inductance parameter determining method, an inductance parameter determining device, a storage medium and a synchronous reluctance motor. The method includes the steps: acquiring a group of torque set values of the synchronous reluctance motor; solving d-axis inductance and q-axis inductance linear equations of the synchronous reluctance motor based on the group of torque set values to obtain a group of d-axis and q-axis inductance changing along with the torque set values. The method can solve the problem that a changing curve of the d-axis and q-axis inductance ofthe synchronous reluctance motor changing along with torque is acquired by finite element simulation fitting, so that accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a method, device, storage medium and synchronous reluctance motor for determining inductance parameters, and in particular to a method, device, storage medium and synchronous reluctance motor for determining inductance parameters of a synchronous reluctance motor. Background technique [0002] In the field of industrial control, rare earth permanent magnet synchronous motors are widely used in various fields because of their unique advantages. However, as the price of rare earths rises, the cost of motor manufacturing increases, and the cost advantage is lost, and the development of rare earths is likely to cause environmental pollution, so motors that do not use or use less rare earth materials have become the focus of research. The synchronous reluctance motor does not contain rare earth permanent magnets, and mainly relies on the dq axis inductance difference to gen...
