ABSTRACT:
An electric control arrangement for controlling the speed of a roll driving motor for rolling mills for manufacturing hollow blocks is described. A power controller determines from the speed, field strength and armature current of the driving motor, the actual value of the motor power, compares the latter with a reference value, and generates a controlled variable which is fed to a current controller of the control arrangement to control the motor so that the motor delivers constant power.
