Diagnosis of Mechanical Faults in Electric Motors

The ability to monitor the condition of an electrical machine has been a concern of industry for many years. Knowing when a machine requires maintenance allows users to perform the required maintenance at their convenience, rather than during costly unscheduled shutdowns. This need for improved industrial monitoring techniques has produced a number of studies on the detection of mechanical faul...

Recent Advancement in the Thermal Design of Electric Motors

Traditionally electric motor manufactures have tended to concentrate effort on improving the electromagnetic design and have only dealt with the thermal design aspects superficially. However the increasing requirement for miniaturisation, energy efficiency and cost reduction, and the need to fully exploit new topologies and materials, make it imperative to analyse the thermal circuit to the sam...

Parameter estimation and reliable fault detection of electric motors

Accurate model identification and fault detection are necessary for reliable motor control. Motor-characterizing parameters experience substantial changes due to aging, motor operating conditions, and faults. Consequently, motor parameters must be estimated accurately and reliably during operation. Based on enhancedmodel structures of electric motors that accommodate both normal and faulty mode...
