Permanent Magnet Brushed DC-Motor
2020The mathematical model of these motors is derived. Then, the novel passivity-based approach is applied to permanent magnet brushed DC-motors. Although control of these motors are underestimated in the control community, we point out several problems that have not been considered by researchers which we succeed to solve in this chapter.

Permanent magnet motor magnetizing and calibrating
Proceedings of Electrical/Electronics Insulation Conference, 2002The types of magnetizing equipment that are available include capacitive discharge, half-cycle and electromagnet units. The applications for, and limitations of, each type of unit are briefly reviewed. The range of permanent magnet materials commercially available.

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.

Bipolar Permanent Magnet Stepper Motor
2020We derive the mathematical model of this class of motors. Then we design the proposed control schemes in original coordinates, i.e., a dq transformation is not required. We formally solve the velocity and position regulation problems. A pendulum is included as the load in the position control problem.

Hybrid permanent-magnet synchronous motor.
IEEJ Transactions on Industry Applications, 1990A number of configurations for interior permanent-magnet type synchronous motors have been developed in recent years. This paper describes a form of motor having large output and high efficiency. Use can be made of samarium cobalt magnets, and the volume of the magnets used in the rotor is small compared with that of the conventional permanent-magnet ...

Induction versus permanent magnet motors
IEEE Industry Applications Magazine, 2009It is clear that a premium will continue to be placed on energy efficiency in motors. The circumstances around global warming and the availability of future oil supplies only increase the focus on electric motors as key elements in the efficient utilization of energy resources. PMs offer an important tool in the quest for cost-effective ways to further

Permanent magnet excited synchronous motors
Electrical Engineering, 1955FRACTIONAL-HORSEPOWER synchronous motors are generally available for quantity production in only the reluctance or hysteresis types. The reasons for this are: the simplicity of their rotor constructions, because of the omission of d-c excitation; and the possibility of assembling the rotors of either type in standard induction motor frames ...
