Syllabus

Introduction, Magnetic fields, materials and circuits (5 lectures): • Electric machines and their applications. • Fundamental material on magnetic fields. • Faraday’s law of induction and magnetic force calculation. • Magnetic circuits and inductance. • Properties of magnetic materials. • Case study: Coriolis mass flow meters and Sterling engine micro CHP. Synchronous generator (2 lectures): • Construction and principle of operation of synchronous generators. • Farady’s law is applied to calculate the emf of a synchronous generator. • Circuit simulations will be used to calculate the rectified voltage regulation of such generators. • Case study of high-speed PM synchronous generators for exhaust energy recovery. Three-phase circuits and Power system stability (8 lectures): • Review of AC circuit theory. • Three phase circuits, power calculations, reactive power, power factor and power factor corrections, per unit systems, • Types of stability study, the swing equation, application to transient stability analysis of a single generator connected to an infinite bus. DC Machines (5 lectures): • Machines construction and principle of operation, • Relationship between torque and size and the calculation of Kt and Ke. • Different types of dc motor and their torque-speed characteristics. Brushless DC motors (16 lectures): • Construction and principle of operation of the brushless dc motor with trapezoidal emf and quasi-squarewave currents. • Design choices (number of poles, rotor configuration, number of slots etc.) • Detailed motor design (sizing) example. • Case Study: Rim driven thrusters. The students then have the opportunity to design a brushless dc motor for a rim driven thruster.
