Geared dc instrument motor
The 1271 geared instrument dc motor is ideally suited to a wide range of
applications requiring a combination of low speed operation and small unit
size. The integral iron core dc motor provides smooth operation and a bi-
directional variable speed capability while the gearhead utilises a multi-
stage metal spur gear train rated for a working torque up to 0.2 Nm.
The unit, which is suitable for mounting in any attitude, provides reliable
operation over a wide ambient temperature range and is equipped with an
integral VDR ( voltage dependant resistor ) electrical suppression system to
minimise electrical interference.
The 1271 unit offers a range of gear ratio options for operating speeds from
5- 200 rpm and is ideally suited to applications where small size and low
unit price are important design criteria.
