PROBLEM TO BE SOLVED: To solve a problem that the number of components increases to raise up a cost for measuring motor speed and position information and detecting the origin.SOLUTION: A motor control device includes: a code wheel 202 formed with a first scale 204 and a second scale 203; an encoder 201 receiving reflection light on the first scale 204 and the second scale 203 and generating encoder signals; binarization processing sections 102a and 102b for generating speed/position information measuring signals from the encoder signals; a binarization processing section 102c for generating an origin position detection signals from the encoder signals; and a position information measuring section 104 for measuring a position of a motor 111 on the basis of the speed/position information measuring signals, and determining an origin position of the motor 111 on the basis of origin detection signals. |
