摘要: A reversible pulse-motor driving circuit comprising a steady driving circuit composed of an oscillator circuit, a frequency divider circuit, a waveform conversion circuit, and a driving circuit, and a fast correction driving-circuit composed of a fast correction set-circuit, a first gate circuit, a detector circuit, a normal and reverse discrimination circuit, a conversion change-over circuit, a pulse selector circuit, a first memory circuit, a second gate circuit and a second memory circuit, whereby a user can hear a time signal delivered from a calculation circuit and only push a pushbutton to rotate the pulse motor in a reverse direction when the second hand is ahead of the correct time, and rotate the pulse motor in a forward direction when the second hand is lagging with respect to the correct time, and the use of a frequency higher than the steady driving frequency permits a fast setting of the second, minute or hour hand to the correct time. A reversible pulse motor for use in timepiece and more particularly in wrist watch is disclosed which can be rotated in forward and reverse directions by the driving circuit, which is small in size and which can operate with a minimal consumption of the electtric power.

摘要: A pulse motor for clockworks and the like in which the rotor comprises two spaced-apart permanent magnetic disks mounted upon a common shaft and rotatable with respect to a stator. The stator comprises a respective pair of magnetic poles in the plane of each disk, the poles of the pair being interconnected by a shank and a coil wound upon the respective shanks, the coils lying on opposite sides of the rotor. The coils can be excited independently to cause the respective pair of poles to magnetically cooperate with the respective disk and rotate the motor in the forward or the reverse sense.

摘要: The present invention provides a micro stepping motor for more accurately stepping and positioning a magnetic head in a magnetic disc system. The stepping motor has a permanent magnet type rotor and a stator encircling the rotor, the rotor having a plurality of pole teeth formed therein with a fine pitch and the stator also having a plurality of pole teeth formed therein with a fine pitch and disposed opposed to the pole teeth in the rotor, the stator pole teeth being divided into at least one pair of pole tooth groups which are out of phase relative to each other by an electrical angle of 180 degrees. A single common stator coil is provided to the pair of stator pole tooth groups. Thus, the stepping pitch of the rotor is determined by the pitch in the pole tooth groups, whereby the rotor can steppingly be driven with higher density even by the reduced number of stator coils. In addition, plural pairs of pole tooth groups can be formed such that at least two pairs of pole tooth groups and the corresponding two stator coils will be provided to determine the stepping angle of the rotor optionally under the multi-excitation.
