PROBLEM TO BE SOLVED: To improve a conventional limit angle motor having a low effective magnetic flux which interlinks a coil and a small force density per unit volume, because the motor is of a coreless structure, constructed by merely bonding the coil to an inner surface of a stator base portion. SOLUTION: The limited angle motor is provided with a first magnetic pole 12 projecting from a base portion end face 11a and a pair of second magnetic poles 13 on the stator base portion 11 and is configured so that the coil 15 is disposed at a slot between the first magnetic pole 12 and the respective magnetic poles 13.
