SPEED CONTROL OF ASYNCHRONOUS LINEAR MOTORS FOR VEHICLE DRIVES

GESCHWINDIGKEITSSTEUERUNG VON ASYNCHRONEN LINEARMOTOREN FUER FAHRZEUGANTRIEBE

A comparison between different control systems for asynchronous linear motors shows that frequency control offers advantages with regard to efficiency, reactive power consumption, motor construction and electric brake. Self-controlled inverters are suitable for the supply of the motor with variable frequency and voltage. As compared with rotating asynchronous machines, linear motors, due to their finite length, show differences in their operational behavior which result among other things in a strong speed dependence of the machine characteristics. Hence they require control rules differing from those usual for rotating asynchronous machines. Unilateral linear motors impose special requirements on the control because of their normal forces and their air gap dependent parameters.
