The paper discusses the design of a fault tolerant permanent magnet drive based on a 16 kW, 13000 rev/min aircraft fuel pump specification. A proof of concept' demonstrator has been built to this design and key parameters measured on the demonstrator drive are given. A novel current controller with near optimal transient performance is developed to enable precise shaping of the phase currents at ... View full abstract»

• Design considerations for permanent magnet synchronous motors for flux weakening applications

Publication Year: 1998, Page(s):435 - 440

| | PDF (564 KB)

The required parameter values of a permanent magnet synchronous motor designed for very large power-speed range are determined based on a linear dq model. It is shown that unconventional motor constructions with the d-axis inductance equal to, or bigger than, the q-axis inductance can provide superior torque, power factor and control characteristics. The initial sizing state of a design procedure ... View full abstract»

• Heat transfer in a through-ventilated induction motor

Publication Year: 1998, Page(s):429 - 433
Cited by:  Papers (8)
| | PDF (460 KB)

The effects of varying the cooling air flow and its distribution on the heat transfer in a high-voltage, strip-wound, four-pole induction motor are reported. The flow variations were achieved by altering the motor speed, by removing the wafters, by increasing the flow resistance of the motor air inlets, or by insertion of heat transfer augmentation devices in the stator-frame ducts. Heat transfer ... View full abstract»

• Influence of stator geometry upon vibratory behaviour and electromagnetic performances of switched reluctance motors

Publication Year: 1998, Page(s):462 - 468
Cited by:  Papers (27)
| | PDF (548 KB)

The vibrations and the acoustic noise produced by switched reluctance motors (SRMs) are linked to current waveforms and to their structural properties. The authors carried out a parametric study to quantify the influence of the stator geometry upon vibratory behaviour of a 6/4 SRM. Their study shows the important influence of stator yoke thickness on vibration reduction compared to the other stato... View full abstract»

• Effects of end winding porosity upon the flow field and ventilation losses in the end region of TEFC induction machines

Publication Year: 1998, Page(s):423 - 428
Cited by:  Papers (7)
| | PDF (536 KB)

The authors describe the fundamental nature of the flow field and the influence of the end winding's porosity within the end region of a TEFC induction machine. A simulated end winding of simplified geometry was used for the investigation. Effects upon the flow field and ventilation losses are reported. Owing to the physical size and positioning of the end winding, changes in porosity produce larg... View full abstract»

• Experimental investigations on the stators of electrical machines in relation to vibration and noise problems

Publication Year: 1998, Page(s):455 - 461
Cited by:  Papers (7)
| | PDF (760 KB)

Accurate assessment of excitation forces and vibration behaviour is essential to arrive at a suitable design for the quiet operation of an electrical machine. From the vibration point of view, the stator of an electrical machine can be modelled as a system consisting of a number of masses interconnected by springs and damping elements to facilitate the analytical solution of the dynamic behaviour ...

• Design optimisation of electric motors by genetic algorithms

Publication Year: 1998, Page(s):475 - 483
Cited by:  Papers (53)
| | PDF (832 KB)

A new approach to the design optimisation of three-phase electric motors is presented. The novelty lies in combining a motor analysis procedure with a genetic algorithm to optimise an objective function such as the motor torque, the efficiency, the material cost or some other motor figures or a combination of these. Two approaches to the motor analysis are presented: the first is based on a fully ... View full abstract»

• Influence of rotor skew on cage motor losses

Publication Year: 1998, Page(s):414 - 422
Cited by:  Papers (16)
| | PDF (916 KB)

A technique for calculating the total losses in a skewed induction motor, based upon a multi-slice finite-element model, is presented. The ability of this model to predict the axial variation in flux-density in the motor is initially verified. The model is then used to investigate how skew affects the losses in one induction motor. It is shown that skew alters the balance between the rotor iron lo... View full abstract»

• Design of an in-wheel motor for a solar-powered electric vehicle

Publication Year: 1998, Page(s):402 - 408

| | PDF (1108 KB)

The design of an in-wheel electric motor for the solar-powered vehicle Aurora', entered in the 1996, 3010 km Darwin-Adelaide World Solar Challenge solar car race is described. Compared to other entrants in the race, the brushless DC motor is more efficient (97.5% compared to 92-95%) and lighter (8.3 kg compared to 12-16 kg) than all other direct-drive motors, and more efficient than all motor/gea...

• Dynamic modelling and control of a normal-force actuator

Publication Year: 1998, Page(s):449 - 454
Cited by:  Papers (1)
| | PDF (624 KB)

The authors describe the dynamic modelling and control of a simple form of electromagnetic actuator comprising a laminated core with a coil and a `mover' section of the magnetic circuit separated by a small airgap. The modelling of the ideal case, in which a constant voltage is applied to the coil, is considered first. The important idea of control using freewheeling is then introduced. The model ...

• Corona screen effectiveness in large machines under high voltage, high frequency transient conditions

Publication Year: 1998, Page(s):469 - 474
Cited by:  Papers (4)
| | PDF (572 KB)

The slot sections of pre-formed coils used in the manufacture of stator windings for high voltage rotating machines are conventionally finished with a layer of graphite loaded tape, known as a corona screen, for the purpose of suppressing electrical discharge between the coil side and slot wall. The screen resistivity is a compromise between the requirement to limit voltage rise on the screen betw... View full abstract»

• Impact of surface coating insulation on small motor performance

Publication Year: 1998, Page(s):409 - 413
Cited by:  Papers (5)
| | PDF (520 KB)

A range of tests exist for the characterisation of the surface insulation of motor steels. Attempts to correlate readings from these tests with expected motor performance suggests that, at low interlaminar EMFs, formalised insulation may be of secondary importance. However, coatings continue to play a key role in machine fabrication View full abstract»
