Sensorless position control of permanent magnet motors with pulsating current injection and compensation of motor end-effects [PDF]

, 2011
The sensorless position control of permanent-magnet motors is successfully implemented by superimposing a high-frequency voltage signal on the voltage reference or adding a high-frequency current signal to the current reference.

A Torque Sharing Optimization Control Strategy for Switched Reluctance Motors [PDF]

Zhengzhou Daxue xuebao. Gongxue ban
Aiming at the problem of larger torque ripple of switched reluctance motors, a compensation cosine torque sharing optimization control strategy for switched reluctance motors was proposed by improving the traditional cosine torque sharing function. Based

‘Semipole’ reluctance motors

Electronics Letters, 1968
A novel mode of operation of a reluctance motor is described. The motor combines the advantageous feature of a one-piece lamination, usual with conventional salient-pole designs, and an improved synchronous performance approaching that of the newer segmented-rotor designs. Pull-in performance is good, particularly with high inertias.

Computation of the voltage-driven flux-MMF diagram for saturated PM brushless motors [PDF]

, 2005
The flux-MMF diagram or "energy conversion loop" is a powerful tool for computing the average torque of saturated permanent-magnet brushless motors, especially when the assumptions underlying classical dq theory are violated, as they often are in modern ...

Vectorial formalism for analysis and design of polyphase synchronous machines [PDF]

, 2003
A vectorial formalism for analysis and design of polyphase synchronous machines without reluctance and saturation effects is described. We prove the equivalence of such a machine with a set of magnetically independent machines, which are electrically and

Access to Finance and Innovation in the Canadian Food Processing

Agribusiness, EarlyView.
ABSTRACT Innovation is a presumed channel through which finance affects productivity, yet there is limited research testing the relationship between finance and innovation in the food manufacturing sector. The purpose of the paper is to explore the determinants (e.g., financing, R&D, firm size, expenditure on innovation) of the adoption of innovation ...
