Abstract
A motor device includes a motor, a motor driving control device and a position detector for outputting a position detection signal. The motor includes magnetic poles (n*6) and coils wound around teeth (n*4) where n is a positive integer. The coils are arranged in a peripheral direction such that the first-system coils and the second-system coils are alternately arranged. The motor driving control device includes a first drive circuit and a second drive circuit, each including an inverter circuit and a control circuit portion. The first drive circuit energizes the first-system coils and the second drive circuit energizes the second-system coils at an energization timing different from that of the first-system coils.
