摘要： A positioning controller includes a gear mechanism having a rotating gear for positioning a movable member, a brushless motor to drive the rotating gear, and a motor control circuit to rotate a rotor of the brushless motor by sequentially supplying a driving pulse to a plurality of fixed coils of the brushless motor. The motor control circuit includes a present stage number detector to detect a present stage number of the movable member in accordance with an output signal from a magneto-sensitive device of the brushless motor, and a driving pulse generator to generate a driving pulse to rotate the rotor until a target stage number converted from a specified position of the movable member is equal to the present stage number. The controller in an apparatus including a motor driving unit allows positioning of the movable member without using a component for the detection of the position of the movable member.

摘要： A drive system for a brushless motor. The brushless motor includes a rotor having opposite magnetic poles on its periphery, and a stator facing the rotor. The stator has, for example, three interconnected coils at equal angular intervals. The drive system includes a memory for storing drive data which represent drive currents supplied to the respective coils at each angular position of the rotor. The drive system also includes a controller for reading those drive data which best match a target angular position of the rotor, from the memory. The controller generates drive signals based on the drive data. The drive system also includes a drive circuit for supplying the drive currents to the respective coils, based on the drive signals, respectively. The drive system can precisely control the angular position of the brushless motor.
