Full Description

Scope

To assist in providing a uniform method for calculating and measuuring torque pulsations which occur during starting of synchronous motors. Synchronous motors as discussed in this guide specifically refer to salient-pole type motors with wound main field circuits with either a continuous or interrupted amortisseur cage/ In modern installations, direct current is applied to the main field by means of slip rings from a static exciter or by a rotating brushless excitation system to establish synchronous operation.

Purpose

Define electromagnetic torque pulsations which occur during starting of synchronous motors; Recommends a standard equivalent circuit that can be used to analytically describe the behavior of the synchronous motor during starting; provide the definitions and information necessary to properly determine the circuit parameters in the equivalent circuit; supply equations derived from the circuit which can be used to calculate the magnitude of the torque pulsation which would occur during starting; present a uniform technique for the on-line measurement of torque pulsations during starting based on equations derived from the equivalent circuit.

Abstract

New IEEE Standard - Active.A uniform method for calculating and measuring torque pulsations that occur during start-ing of synchronous motors is provided. Synchronous motors, as discussed in this guide, applies toall types of excited synchronous motors, including laminated or solid, salient or nonsalient ma-chines, as well as nonexcited synchronous-reluctance motors.
