Abstract

A method and apparatus is described for damping oscillations in the rotor load angle of a synchronous motor to provide stable rotational alignment in high precision applications. The damping method includes sensing the angular position of the rotor and utilizing the position signal to generate an error signal in response to changes in the period of rotation of the rotor. The error signal is coupled to phase shift amplifiers which shift the phase of the motor drive signal in a direction to damp out the oscillations in the rotor load angle.

Control for stabilizing the alignment position of the rotor of a synchronous motor

Patent Donley, L.I.

A method of stabilizing the rotational alignment of the rotating rotor of a synchronous motor driven with a period of rotation determined by a drive signal that is generally synchronized to a clock signal generated by a master clock, wherein the master clock includes means for permitting abrupt changes in the frequency of the drive signal, is described comprising the steps of: magnetically sensing the rotor and generating a pulse in response to the rotor reaching a predetermined angular position; generating an error signal by generating high frequency clock pulses, accumularing a count of the clock pulses on successive periodsmore »« less

Synchronous motor with soft start element formed between the motor rotor and motor output shaft to successfully synchronize loads that have high inertia and/or high torque

Patent Umans, Stephen D; Nisley, Donald L; Melfi, Michael J

A line-start synchronous motor has a housing, a rotor shaft, and an output shaft. A soft-start coupling portion is operatively coupled to the output shaft and the rotor shaft. The soft-start coupling portion is configurable to enable the synchronous motor to obtain synchronous operation and to drive, at least near synchronous speed during normal steady state operation of the motor, a load having characteristics sufficient to prevent obtaining normal synchronous operation of the motor when the motor is operatively connected to the load in the absence of the soft-start coupling. The synchronous motor is sufficiently rated to obtain synchronous operationmore »« less

Control system for a wound-rotor motor

Patent Ellis, J.N.

A load switching circuit for switching two or more transformer taps under load carrying conditions includes first and second parallel connected bridge rectifier circuits which control the selective connection of a direct current load to taps of a transformer. The first bridge circuit is normally conducting so that the load is connected to a first tap through the first bridge circuit. To transfer the load to the second tap, a switch is operable to connect the second bridge circuit to a second tap, and when the second bridge circuit begins to conduct, the first bridge circuit ceases conduction because themore »« less
