Course Description

Overview of topologies of electrical machines of special construction, principles of operation, characteristics and fields of their application on examples of electrical actuators, brushless DC motors, universal motors, axial flux and transverse flux motors, switched reluctance motors, stepper motors, Vernier motors, linear motors, and line-start permanent magnet motors

Learning Outcomes

  1. Explain the basic principles of electromechanical conversion and heat transfer
  2. Explain the working principles of electrical actuators, brushless DC motors, universal motors, synchronous reluctance motors, switch-reluctance motors, stepper motors, linear motors, and line start permanent magnet motors
  3. Define the characteristics of the electrical actuators, brushless DC motors, universal motors, synchronous reluctance motors, switch-reluctance motors, stepper motors, linear motors, and line start permanent magnet motors
  4. Analyze the performance of the electrical actuators, brushless DC motors, universal motors, synchronous reluctance motors, switch-reluctance motors, stepper motors, linear motors, and line start permanent magnet motors using numerical methods
