IPC: H02K29/00
Filed: 1979-11-22
Abstract: PURPOSE:To reduce torque ripples and to eliminate the dead point of the torque by shfiting the peak point of the field flux from the center of a pole, and driving a plurality of stator windings by two-phase waves. CONSTITUTION:A rotary shaft 1 can be freely rotated in a stator frame 11 via bearings 10. The shaft 1 is installed to a rotor field magnet 8 formed by a permanent magnet via a deformed ring 7 acomrising a soft magnetic material. While a stator 6 is formed with the soft magnetic material. One slot is formed for one pole. The width m1 of the teeth of the stator 6 is shorter than the pole pitch so as to obtain the specified short-pitch factor for the stator windings 2-5. The path of the magnetic flux in the section between the pitches tau1-tau0 in the rotor field magnet 8 is thin, and becomes thicker toward tau2 in the other section between tau2-tau1. Therefore, the deformed ring 7 is formed by cutting a circular cylinder having a radius m3 in the axial direction as shown by the length of a chord m2. Thus, the dead point of the torque can be eliminated.

Abstract: PURPOSE:To give a vibration to abrasive grains flowing down, disperse these abrasive grains in slurry uniformly, and shorten a span of lapping time as well as to improve the extent of accuracy of finishing, by lapping a workpiece as giving the ultrasonic vibration to the workpiece or the slurry. CONSTITUTION:A single crystal 1 of LiTaO3 of about 3 inches in diameter and about 100mm in length is stuck plate 8, a Langevin vibrator 7 is set up in the lower part. And, the glass 8 is vibrated at about 50W/cm<2>, and a piano wire 5 is wound up on a roller 6 while adding slurry 3 on the single crystal 1, thus cutting takes place. If so, within about 8hr in machine time and about 5mum in straightness of a wafer, a surface becomes smoothed. On the other hand, if the same machining is performed without giving any vibration, the machining time is about 20hr and the wafer straightness comes to about 20-30mum. Thus, a workpiece is machined as giving an ultrasonic vibration whereby the machining time is reduced and, what is more, accuracy of finishing is improvable.
