Abstract
This invention is concerned with an electronic damper for a pulse motor wherein at the time of oscillation or rotation of a rotor in a pulse motor of a 1-phase excitation method having at least one pair of windings wound up to generate electromotive forces with the opposite polarities, a switching element is actuated in synchronization with completion of pulse driving the pulse motor, said one pair of windings are connected through a capacitor and the rotor can be brought to a standstill immediately by neutralizing the electromotive forces led up to each winding.
Claims7
An electronic damper for a single phase excitation type pulse motor having a natural resonance frequency, including pairs of opposed windings for generating electromotive forces of opposite polarity due to movement of said rotor, comprising capacitor and switch means coupled in series between said pairs of opposed windings, for completing, after termination of an output pulse to said pulse motor, a series resonant circuit comprised of said capacitor and said pairs of windings, wherein said series resonant circuit resonant frequency is selected from the range of one-half to twice said motor resonance frequency.
An electronic damper for a single phase excitation type pulse motor having a natural resonance frequency, including pairs of opposed windings having a d.c. resistance, said windings generating electromotive forces of opposite polarity due to movement of said rotor comprising:
- a series circuit in series with said pairs of winding including a capacitor, negative resistance means for neutralizing said winding d.c. resistance, and switch means for coupling after termination of an output pulse to said pulse motor, said series circuit to said windings.
