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

摘要： Disclosed is a direct current motor which comprises an armature, provided with armature windings thereon, and a plurality of field magnet devices, each of the field magnet devices being divided into three parts along the rotational direction of the armature. The parts are a main pole, which consists of a permanent magnet or an electromagnet activated by field windings wound thereon and which is disposed at a central portion of the field magnet device, and a pair of auxiliary poles, each of which consists of a permanent magnet. One of the auxiliary poles is disposed at one end of the main pole and the other auxiliary pole is disposed at the other end of the main pole. The permeability of the auxiliary poles is selected to be smaller than that of the main pole, and the polarity of the auxiliary poles is selected to be the same as that of the main pole.Since the permeability of the auxiliary poles is small, magnetic flux generated by the armature current is very small at a position adjacent to each end of the field magnet devices and is substantially equal to zero at a central position adjacent to two field magnet devices (on the geometric neutral axis). Consequently, the displacement of the electrically neutral axis caused by the armature reaction can be prevented and, as a result, degradation of the commutating characteristics does not occur.
