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
