摘要： A motor-incorporated spindle head unit is provided with a rotatable spindle (12) on which a rotor assembly (32) of the drive motor (30) is fixedly mounted. A stator assembly (34) of the drive motor is arranged around the rotor assembly (32) and is fixed to a housing (20) of the spindle head unit. A heat insulating system (50) for preventing heat transfer from the stator assembly (34) of the drive motor (30) to the spindle (12) as well as the bearings (16) supporting the spindle (12) is arranged between the drive motor (30) and the front part (14) of the spindle. The heat insulating system (50) uses the flow of air for forming a heat insulator during the operation of the spindle head unit. A cooling system (36-44) for cooling the stator assembly (34) of the drive motor (30) is also incorporated in the housing (20) of the spindle head unit.

摘要： A direct current motor used, for example, in a machine tool, comprising an armature (1), n main magnetic poles (3,4) disposed around the armature, each of the main magnetic poles consisting of a pole core (33,43) on which a field winding (5,6) is provided and a pole piece (34,44) extending along the outer circumference of the armature, and n/2 E-shaped interpoles (8) disposed at the intermediate position along the outer circumference of the armature between the adjacent main magnetic poles, and at the central axls (0) of the armature, the angle (a) spanning from the direct axis (B), which is electrically perpendicular to the interpole axis (A), to an end portion (31) of a pole piece (34,44) of a main magnetic pole (3, 4) is unequal to that (ß) from the direct axis (B) to the other end portion (32) of the pole piece (34, 44) of the main magnetic pole.
Since the number of the E-shaped interpoles is decreased by half, the direct current motor according to the present invention has simple structure and high torque, and the heat generated by the interpoles is relatively decreased.-

摘要： In a direct current motor having E-shaped interpoles, each of the E-shaped interpoles (8') includes interconnecting members (84, 85) which are made of a rigid non-magnetic material and which are tightly inserted and positively retained in gaps between a centre pole (81') and side poles (82', 83') of the E-shaped interpole. The side poles are thereby mechanically interconnected to the centre pole, so that noise generated by vibration of the side poles is greatly reduced.
