Abstract
Provided are a method and apparatus for determining motor temperature, and a storage medium. The method includes: obtaining an electromagnetic loss of each node in ξ nodes acquired by decomposing components of a motor, wherein the ξ is a natural number greater than 1, and at least one component in the components of the motor is decomposed into multiple nodes in the ξ nodes; obtaining a thermal resistance between every two nodes in the ξ nodes; and determining a temperature of the motor based on the electromagnetic loss of the each node in the ξ nodes and the thermal resistance between the every two nodes in the ξ nodes.
