Claim One:
1. A method to control a motor which is electrically excited, the method comprising: providing a drive comprising the motor and an inverter; and providing a unit which utilizes a first learning method to analyze processes in machinery which comprises the drive, the motor and the inverter so as to learn to control a variable motor flux of the motor, wherein the unit thereby: analyzes a first selection of signals available in the machinery so as to directly learn to determine a minimal current value of the variable motor flux necessary for the motor to generate a torque which is required in a near future, and sets the variable motor flux to be sufficient to operate the machinery and to minimize motor losses of the drive, or analyzes the first selection of signals available in the machinery so as to learn to predict a future torque demand, uses the future torque demand predicted to determine a minimal necessary motor flux required, and sets the variable motor flux to be sufficient to operate the machinery and to minimize motor losses of the drive.
