The subject of this book is an important and diverse field of electric machines and drives. Electrical machine and drive has published 25 papers in conferences and journals and has 8 patents. As a graduate student his research focused on electrical machine and drive vehicle drivetrain and energy storage system design, modeling, and fabrication.
Another special case would be the brushless double fed induction machinewhich has a double set of coils in the stator. Since it has two moving magnetic fields in the stator, it gives no meaning to talk about synchronous or asynchronous speed.

Reluctance machines[ edit ] Reluctance machines have no windings in rotor, only a ferromagnetic material shaped so that "electromagnets" in stator can "grab" the teeth in rotor and move it a little.
The electromagnets are electrical machine and drive turned off, while another set of electromagnets is turned on to move stator further.
Another name is step motor, and it is suited for low speed and accurate position control.
Reluctance machines can be supplied with PMs in stator to improve performance. Electrostatic machines[ edit ] In electrostatic machinestorque is created by attraction or repulsion of electric charge in rotor and stator.
Electrostatic generators generate electricity by building up electric charge. Early types were friction machines, later ones were influence machines that worked by electrostatic induction.
The author carefully deploys physical insight, mathematical rigor, and computer simulation to clearly and effectively present electric machines and drive systems.
