Abstract
During various transient phenomena of an asynchronous machine, oscillations of mechanical characteristics (speed, torque) of the machine occur very frequently. Very fast oscillations of speed of the electric drive may be detected by using a speed-voltage generator or incremental sensors, however, the precision is not high, or the requirements placed on the measuring instruments are strong. The submission offers a possibility of how to exploit the advantages of the accelerometer with permanent magnets for determining these oscillations. The requirements on the measuring chain are also substantially lower.
