Series-Impedance Starting

Series-Impedance Starting. Impedance Z is either an Inductor or a Resistor to limit the current during start-up. Series-Impedance Starting continued. Select the resistor or inductor (reactor) to provide about 70% rated voltage. Simplest method for starting. Example 5.20.

Identifying Three Phase Induction Motor Equivalent Circuit Parameters from Nameplate Data by Different Analytical Method

The induction motor equivalent circuit parameters are required for many performance and planning studies involving induction motors. These parameters are typically calculated from standardized motor performance tests, such as the no load, full load, and locked rotor tests. However, standardized test data is not typically available to the end user. Alternatively, the equivalent circuit parameters may be estimated based on published performance data for the motor. Methodologies for obtaining the parameters of the equivalent circuit for an induction motor from the information on the nameplate and an analysis is presented so that the typical parameters of an equivalent circuit can be readily estimated.
