PURPOSE:To reduce the quantity of transistors to about half and make the title controller inexpensive, by a method wherein shared transistor arms and (n) pieces of individual transistor arms provided to control (n) sets of DC motors. CONSTITUTION:A transistor QAO and the transistor QBO constitute a transistor arm shared for the control of a plurality of motors M1, M2...Mn. The transistor QA1 and the transistor QB1 constitute an individual transistor arm for the motor M1. The transistor QA2 and the transistor QB2 constitute the transistor arm for the motor M2. The transistor QAn and the transistor QBn constitute the transistor arm for the motor Mn. The normal rotation, reverse rotation and braking operation of the motor M1 are controlled by controlling the transistors QA1, QB1. Only one set among (n) sets of motors M1, M2..., Mn is selected to control the normal rotation, reverse rotation and braking operation. |
