Design of Electromagnetic Torque Rods
1965Abstract : This report is a compilation of considerations involved in the design of electro-magnetic rods for satellite erection. Formulae are derived showing the effect of various choices of core and wire material and weight, number of cores, length of cores, number of turns per core, and wire area on the magnetic moment, hysteresis power, hold power,

Anisotropy component of electromagnetic force and torque
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2010The paper deals with the problem of surface-integral representation of electromagnetic force/torque for magnetically anisotropic region. It is pointed out that in some anisotropic regions a component of electromagnetic force/torque appears the so-called anisotropy component.

Review of Scientific Instruments, 2017
In this study, we developed a novel type of rheological measurement system. Here, a spherical probe is driven to rotate periodically by applying torques using quadruple electromagnets in a noncontact manner. Moreover, this system is an enhancement of our electromagnetically spinning (EMS) viscometer, which is widely used for measuring rheological flow ...

Proposal for electromagnetic torque estimation
1999In this paper the proposal for electromagnetic torque estimation for AC slip-ring motor is inestigated. Basicaly, two methods are propsed: electromagnetic torgue estimation based on DC stator voltage and current values and electromagnetic torgue estimation based on the AC stator voltage and currents values.

Force and Torque Production in Electromagnetic Circuits
2011In Chap. 6 inductors have been analyzed. In these devices there are no moving parts. In this chapter the force (\( {\vec{\hbox{F}}} \)) and torque (\( {\vec{\hbox{T}}} \)) production in electromagnetic circuits such as magnets, actuators, relays, linear and rotating machines will be discussed.

Analysis of electromagnetic torque of induction machines with the load torque changes suddenly
2014 17th International Conference on Electrical Machines and Systems (ICEMS), 2014Since many Cascaded H-bridge multilevel (CHBML) inverters that are applied to drive high voltage machines can't transmit electric energy reversely, the electric energy transmitted from the machines may damage the inverters. This paper presents a transfer function to analyze the electromagnetic torque, when the load torque changes suddenly. Based on the

Torque Analysis and Shape Optimization of Electromagnetic Clutch
Key Engineering Materials, 2010This 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.

Electromagnetic torque on the toroidal plasma and the error-field induced torque
Nuclear Fusion, 2007The electromagnetic torque on the toroidal plasma is calculated assuming a linear plasma response to the applied perturbation, which may be the error field or the field created by the correction coils, or both. The result is compared with recently published expressions for the error field induced torque (Zheng et al 2006 Nucl.
