Abstract :
A reversible drive control for elevator doors, using a dc motor with phase controlled power supply, is described. This drive is designed to satisfy the required performance criteria. Part I of the paper uses a separately excited shunt field for reversible operation and in Part II speed reversal is obtained by armature voltage control.
