Stepping Motors
OUTLINE
"M25SP-3", the standard, 25mm outer diameter
model series, and "M25SP-4" type with 15˚ step
angle.
Excitation method and outside dimensions are all
common.
This configuration however allows you to select
the holding, pull-out and pull-in torques suited to
your equipment into which the motors will be
integrated.
FEATURES
1. Compact size and high output torque.
2. Superior running quietness and stability.
3. Step angle : 7.5˚ (M25SP-3), 15˚ (M25SP-4).
4. Excellent responsiveness acquired.
USES
Printers, multifunction machines, copy machines, FAX, and such.
