    • The invention relates to a method for controlling an asynchronous machine, which is operated below a cut-off frequency in the basic rotation speed range with a variable magnetization current and above the cut-off frequency in the field weakening range. The maximum possible fundamental frequency of the stator current (U1) is determined from the available intermediate circuit voltage or battery voltage (UB). A stator current (I1) is predefined as a set value and impressed upon the asynchronous machine. Said rotor frequency (f2alg) is calculated so as to impress the set current value upon setting the stator voltage (U1). The rotor frequency (f2) pertaining to the set current value (I1) is compared with the calculated rotor frequency (f2alg) by means of a characteristic control curve. The higher rotor frequency value thereof is used to determine the set current value. The inventive method is carried out using a microprocessor enabling the calculation algorithm to be processed quickly, effectively and close to real-time. This enables energy available in electric vehicles to used in an optimum manner.

    • The operation of an AC induction motor 24 is controlled in response to the actual slip exhibited by the motor during operation. The slip of the motor 24 may be determined by determining the actual running speed, n, of the motor shaft 25A, measuring the line frequency, n s , of the electricity supplied to the motor, and calculating the slip, S, of the motor using the relationship: S = ((n s - n)/ n s )* 100. If the slip is too high when compared to a predetermined maximum acceptable slip, corrective action is taken to decrease the loading on the motor. If the slip is too low when compared to a predetermined minimum acceptable slip, corrective action is taken to increase the loading on the motor. By adjusting the operation of the system by appropriately changing the load on the motor, or changing the electrical supply parameters, the actual slip exhibited by the motor 24 is returned to a value within the range between the minimum acceptable slip and the maximum acceptable slip, thereby protecting the motor and improving overall reliability.
