INCREMENTAL MOTION CONTROL SYSTEM WITH ASYNCHRONOUS MOTOR

IFAC Proceedings Volumes, 1983
Abstract The possibilities of incremental motion control, with asynchronous motors are discussed. Various dc link static converters are shown, which provide the motor step by step operation, when the discrete information items into elementary displacements of the rotor are converted. An analytical expression of the electromagnetic torque developed by

Instability Regions of Variable Frequency Supplied Asynchronous Motors

IFAC Proceedings Volumes, 1983
Abstract The paper tries to answer the question if and when unstable operations occur in practice in asynchronous motors supplied by variable frequency voltages. It is found and shown that unstable operating ranges are in practice greatly reduced in comparison with theoretical evaluations, obtained by simply considering the independent variation of ...

Telemetry diagnostic capabilities for asynchronous motors

2012 XXth International Conference on Electrical Machines, 2012
Diagnostic tests of electrical machines are part of improving operational reliability of these devices over a long period of time. This justifies the monitoring of machines, particularly those which do not have the reserve at the workplace: the power generators, hoisting machines in mines, etc.

Asynchronous reluctance motor using ferroresonance

Proceedings of the Institution of Electrical Engineers, 1967
This paper shows how asynchronous operation of a reluctance motor may be obtained by taking advantage of one of the properties of a series LCRcircuit, in which the inductance is a function of current. Parametric variation of the machine inductance is accomplished by variation of the rotor iron-circuit reluctance, instead of the more conventional change
