Title :
Quality Improvement of a Variable Speed Drive in V/f Mode - Numerical Evaluation of Crucial Influences
Author_Institution :
Siemens AG, Erlangen
Abstract :
Undesired secondary effects occurring at inverter-fed squirrel cage induction motors are investigated by a transient two-dimensional finite element analysis with coupled electrical circuits. Calculated time-dependent numerical courses are compared to measured ones. A novel and deeper insight into the invoked harmonic spectrum of the electrical stator current and the mechanical torque at the rotating shaft is given.
