Module Description: This module develops a thorough understanding of electrical machines and their interaction with power electronic converters and mechanical loads. It takes a broad-based approach that enables the student to make a significant contribution to the design of a complete drive system for commercial, industrial and transport sectors.
 
Learning Outcomes
On successful completion of this module the learner will be able to:
# Learning Outcome Description
LO1 Analyse the performance of electrical machines in different modes of operation.
LO2 Evaluate the power and torque requirements for common drive applications such as fans, pumps, conveyors, hoists, machine tools, traction.
LO3 Specify and size gear/belt/screw transmission devices for motorised systems.
LO4 Specify appropriate power electronic converters in drive applcations and predict the performance of DC, induction, synchronous and reluctance machines under steady state and transient conditions.
LO5 Discuss and implement Matlab/Simulink and Simscape to design advanced models for data analysis
LO6 Solve machine and drive problems based on calculation and software-based techniques.

Module Recommendations

This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
