Spring-oriented sensor-less regulation of electrical machine starting process involves feeding current to stator, determining electrical resistance of primary circuit from resulting stator voltage

摘要

The method involves feeding an electric current into the stator (5) and determining the electrical resistance of a primary circuit containing the stator from the resulting stator voltage, determining the angular position of the rotor (4) relative to the stator, starting the electrical machine (1) and monitoring the angular position of the rotor relative to the stator while the electrical machine is operating over the entire possible revolution rate range. AN Independent claim is also included for the following: (a) an arrangement for implementing the inventive method.
