CONTROLLING SYSTEM FOR DRIVING GEAR HAVING ASYNCHRONOUS MOTOR

PROBLEM TO BE SOLVED: To provide a new controlling system for a driving gear which enables a stable low-abrasion operation at any operating point in a maximum traction range and which controls as wide a range as possible, without the use of a rotational speed sensor in particular. SOLUTION: In a con...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a new controlling system for a driving gear which enables a stable low-abrasion operation at any operating point in a maximum traction range and which controls as wide a range as possible, without the use of a rotational speed sensor in particular. SOLUTION: In a controlling system 140 for a driving gear having an asynchronous motor, particularly a railway car, the controlling system 140 includes a first control loop 141 for controlling an electric motor and a second control loop 142 which, connected to the first control loop 141, has an adhesion controller 125. The motor controlling system is designed as a controlling system for the frequency of a stator and the actual torque value Mact of the asynchronous motor is calculated inside the motor controlling system. Two control loops are connected to each other, so that the actual torque value from the motor controlling system is used as the actual value for the adhesion controller 125. A control response is improved by making the adhesion controller 125 preset a nominal frequency value of the stator fs.nom for the motor controlling system.
