PROBLEM TO BE SOLVED: To provide a motor coil unit, having a detection coil capable of restricting the generation of noise by improving the wiring pattern for connecting wires in a detection coil to be used for rotation control or position control. SOLUTION: In a motor coil unit which has a rotation speed detecting coil 6, a connecting angleθof a connection wire 10 is arranged by giving a slant of 5 deg. to 85 deg. with respect to the radial direction of the coil unit, at the place where the connecting wire 10 connecting the rotation speed detection coil 6 to its terminal 6t crosses another coil region. When a motor built with this print coil unit is operated, there will be no noise in the signal output of the rotation speed detection coil 6, and accurate rotational speed control is possible.
