This paper deals with the magnet angle design of the interior permanent-magnet motor for high efficiency applications. The permanent magnet angle of line-start motor is important factor to decide the d-q axis inductance and the motor performance. In this paper, we investigate the inductance according to magnet shape and the motor performance of two models is compared.
This paper studies the influence of core material on the design of the interior PM synchronous motor (IPMSM). Two kinds of ferromagnetic steels are selected in this paper. And with these two core materials, two IPMSMs used to drive the electric scooter are designed. First, the parameters of these two motors, including the inductance, iron-loss resistance, and back electromotive force are calculated...
This paper introduces a new analytical method for performing the output torque calculations of an interior permanent magnet synchronous motor (IPMSM) including both permanent magnet and reluctance torque components. This method works well when using a 2-dimensional magnetic equivalent circuit of a machine by omitting the step of calculating the inductance values which are required for the calculation...
