Abstract

An asynchronous motor speed-regulation system is temperature-compensated and adjusted to the actual rotor temperature by calculation of the motor torque actually, developed at a predetermined reference temperature. The calculated torque is compared with an error signal which is the difference between the actual and desired speed of the rotor. The comparison provides an actual rotor temperature which is used to compensate the error signal.
