Abstract
The present disclosure proposes a method and device for optimally designing the topology of a permanent magnet insertion type electric motor by considering maximum torque control performance per ampere and field-weakening control performance. According to the present disclosure, for a topology optimization-based design of an electric motor including a stator and a rotor and having a permanent magnet inserted into the rotor, a computer device is configured to calculate an optimal current control condition for the stator according to a structure of the rotor and to derive a topology optimization-based design of the rotor by applying the optimal current control condition.
