Brushless Synchronous Propulsion Motor
SAE Technical Paper Series, 1968<div class="htmlview paragraph">The development of a brushless synchronous motor with d-c motor characteristics suitable for vehicle propulsion applications is described. The motor is statically commutated, using thyristors triggered by rotor position logic.

Planar Brushless Magnetic Micromotors
Journal of Microelectromechanical Systems, 2006Novel planar magnetic micromotors and microgenerators of active diameter 8 mm were developed, delivering estimated torques of 100 muN.m at speeds in excess of 140 000 r/min. Such high performances are due to an innovative use of deep lithography and silicon etching for the fabrication of the stator coils. The hybrid design of the micromotors combines a

A moving coil brushless motor including an actuator having a stator and a rotor. The stator includes a cylindrical array of permanent magnets. The rotor includes a coil assembly having a plurality of coils interposed between a stator back plate and the permanent magnet array. The coil assembly rotates relative to the array of permanent magnets.

The authors design a variable reluctance motor to perform the rotation of clawed-pole rotors. Starting from this singular problem and encouraged by the good practical results they obtained, they have investigated the structure in terms of motor performances for application in variable speed drives.

Brushless variable-speed induction motors
Proceedings of the IEE Part A: Power Engineering, 1957The first part of the paper describes experiments performed on a spherical machine. These experiments show that speed ranges up to 5.5:1 can be obtained, and that the speed range obtained depends markedly on the ratio of pole width to pole pitch. They also show that the losses in the machine cannot be accounted for by conventional induction-motor ...

Brushless permanent-magnet motor drives
Power Engineering Journal, 1988The brushless PM DC motor is extremely common in a wide variety of low-power applications such as computers and office machinery. As magnetic properties improve and control electronics become more sophisticated, the brushless PM motor expands its application potential to higher power levels.

AC Commutatorliess and Brushless Motor
IEEE Transactions on Power Apparatus and Systems, 1972We have developed a type of ac commutatorless motor which is a combination of a motor and thyristor controller. The rotor of the motor has neither a commutator, slip rings nor brushes. The motor can therefore be designed rugged for a high speed control.
