| titleOfInvention | Apparatus and method for evaluating the speed of a slip ring asynchronous machine |
| abstract | The present invention relates to an apparatus and a method for evaluating the speed of a slip ring asynchronous machine. An asynchronous machine (1) comprises a stator (2) having a stator winding arranged to be supplied with three-phase voltage and current to generate a changing magnetic flux, and a rotor having a rotor winding. And (3) the magnetic flux is set to generate a voltage that generates an electromagnetic torque to drive said rotor (3) at a rotor speed having slippage in relation to the changing rotational speed of the magnetic flux. I have. The device has a measuring element (12) for measuring the value of the voltage of the rotor winding during at least one period, and a calculating unit (17) for calculating a value of the rotor speed from the measured voltage. . |
