Title: Controlling system for motor
Inventor: WATARAI TEISUKE
IPC: H02P29/00
Filed: 1981-06-15
Abstract: PURPOSE:To realize high precision position determination by using a simplified circuit by a method wherein a predetermined quantity of movement from a current position is compared with actual movement and excitation is caused to remain unchanged at a certain point when the difference between the two is less than a prescribed quantity. CONSTITUTION:The rotation of a motor 4 is transmitted to a gear 39 and rotates it. The rotation of the gear 39 is detected by a pickup 40 whose output pulses in turn are processed in a shaping circuit 41. A subtraction counter 43 loses quantity ''1'' when it receives a pulse outputted by the shaping circuit 41. The counter 43 reads ''0'' when the total output of the shaping circuit 1 reaches a quantity equal to what is preset in the counter 43. That is, when what is set in a movement quantity setter switch 38 becomes equal to what the counter 43 counts, the output of the counter 43 becomes ''0''. This in turn results in a ''0'' output (c) of an OR gate 42. This further causes a gate pulse generating circuit 37 to turn off ACC thyristors 34, 35, 36 for the stoppage of the motor 4.
