Product Profile of D. C. Stepping Motor
Gravity Engineering manufactures D.C. Stepping Motor. Gravity Engineering manufactures Miniature Synchronous AC/DC Gear Motors. The D.C. Stepping Motor is an electromagnetic device, which converts digital pulses into discrete mechanical rotational movements. The motors are hybrid type uni-polar or bipolar having multi- toothed rotor & stator. The rotor uses permanent magnet & the stator is two phase pair [four phase] bifilar winding, with 6 leads or 8 leads.
Special features of D.C. Stepping Motor:
A wide range of rotating speeds [stepping rate] proportional to the frequency of the pulse signal is provided
The rotating angle of the motor is directly proportional to the number of input pulses
The angle error per step is very small & non-cumulative
Rapid response to starting / stopping & reversing
Digital input pulse signal provide open-loop control, thus making the system simple & avoiding the need for closed loop system for less critical application
Self-holding capability makes it possible for the rotor to be held in the stepped position without the use of brakes
