Zusammenfassung:	A two-phase motor with high space utilization efficiency is provided for driving a hydraulic control valve. A valve drive motor (15) includes a rotor (70) and a stator (80) surrounding the rotor (70). The rotor (70) has six magnetic poles. The stator (80) includes six stator windings (83U1, 83V1, 83U2, 83V2, 83U3, 83V3). The stator winding (83U1) and the stator winding (83V1) constitute a pair of two-phase stator windings. The stator winding (83U2) and the stator winding (83V2) constitute a pair of two-phase stator windings. The stator winding (83U3) and the stator winding (83V3) constitute a pair of two-phase stator windings. The two stator windings of each pair are disposed at an angular interval of 180 degrees in terms of an electrical angle.
