Abstract
Purpose In the present paper the influence of the magnetization patterns of rotor magnets on the performance characteristics of a surface permanent magnet (SPM) motor has been investigated. The purpose of this paper is to show how the electromagnetic and electromechanical characteristics of this type of motor can be significantly changed by applying various magnetization patterns of permanent magnets (PM) on the rotor surface.
Highlights
In the present paper the influence of magnetization patterns of the rotor magnets on the performance characteristics for surface permanent magnet (SPM) motor is investigated
The analysis model is a surface permanent magnet motor with 18 A rated current, 0–10 Nm torque control, and 0–4000 rpm speed control
Since the presented research has a comparative character, it is developed into three levels. It is started with a conventional SPM synchronous motor with segmented permanent magnets; two magnetization patterns are considered: parallel and radial, as presented in Figure 3 (a) and (b)
Summary
The demand for more compact and more effective electric machines attracted the attention of researchers and manufacturers towards the permanent magnet machines. The permanent magnet motors (PMMs) are more and more recommended and used in the industrial applications, mainly due to the increased power density, higher efficiency, better dynamic performance and higher values of torque per unit volume. Knowing that their design is simpler with increased life time and easier maintenance, the advantages of PM motors are evident. The presented study has a comparative character, between conventional surface PM synchronous motor, and its counterparts designed with two modifications of Halbach magnet array configuration. Electromagnetic features, such as electromagnetic field distribution in the motor, magnetic flux per pole and components of the flux density in the air gap, are analysed
