A torque-controllable electromagnetic multiple-disc brake

Tribology International, 1989
Abstract This paper describes a new type of electromagnetic multiple-disc brake for controlling braking torque. The brake consists of a rare-earth permanent magnet, an electromagnet and multiple friction discs. The friction torque is controlled by the electric current in a coil of the electromagnet.

Electromagnetic torque components in the synchronous salient‐pole machine

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 1997
Centres on the decomposition of the total electromagnetic torque of electrical machines for two components. The proposed idea of decomposition relies on the physical meaning of currents that appear in electromagnetic field region. The first torque component acts on external and conduction currents, the second on the material medium particles currents ...

Torque Analysis and Shape Optimization of Electromagnetic Clutch

Key Engineering Materials, 2010
This paper is devoted to the static friction torque of electromagnetic clutch. The torque maximization is also investigated by optimizing the geometrical shape of armature. For the purpose of designing and optimizing electromagnetic clutch, torque prediction is a very important factor.

Torque exerted on anistropic magnetic medium by electromagnetic wave

IEEE Transactions on Magnetics, 1969
The possibility of exerting a torque with a nonzero time average value as a result of interaction of a plane electro-magnetic wave with anisotropic magnetic medium is discussed. The torque per unit volume produced by the action of the magnetic field on the magnetization of the medium is T = M \times H and it arises from the fact that the vector of ...

On calculation of electromagnetic torque in PMDC motor

2006
The electromagnetic torque was calculated directly from the change of magnetic vector potentials at moving conductors of a dc motor with permanent magnets. The higher accuracy of field calculations was achieved using the procedure with Gauss points. Numerical operations which usually diminish accuracy in electromagnetic torque calculations were avoided.
