Permanent Magnet Motors
In this course, construction and operation of PM motor drives will be presented. PM machines are considered to have a higher torque density and effciency than induction machines. Both Surface-mounted PM (SPM) and interior PM (IPM) types are adopted for traction application. However, recent increase in the price of permanent magnets has led to an interesting competition between PM motors, Induction motors and reluctance motors. This module will present the fundamental concept of operation, types of PM motors and also discuss control strategies for the motor. Further, it will take a brief look at available permanent magnets, their properties and their impact on the performance on the machine. Topics covered include: Design and Construction of Permanent Magnet Machines: Motoring and Generation; Fundamentals of IPM and BLDC; Permanent magnets used in PM motors; Maximum torque per amp control strategy and Field Weakening concept.
What you will learn:
- Describe the construction and components of permanent magnet motors
- Compare two types of motor control: Permanent Magnet Synchronous Motors (PMSM) and Brushless DC Motors (BLDC)
- Explain how electromagnetic energy conversion works in PMSM
- Describe elements and process of PMSM drive
- Describe the construction and basic operating principles of switched reluctance motors (SRM)
- Describe challenges with SRM
- Explain impact of various design and control features
- PMSM and BLDC
