Stepper motor

ROTARY STEPPER MOTORS MTS3a

Design

MTS3a, stepper motor is of the permanent magnet type with two stator / four windings, for dc supply, available in both windings unipolar as well as bipolar with step angle of 7.5° which converts electrical pulses into discrete mechanical movements when connected with driver circuit .The 24 pole rotor which has a steel shaft polished to a mirror-finish rotates in sintered bronze bearings. Motor can be provided with Mounting plate/Screw clip for fixing.

Application

Printers, recorders, stepper clocks, robotic applications , packaging machineries, opening & closing actuators , medical instruments , special purpose applications such as; distribution, table movement etc.
