Geared DC Brushed Motors

1271 Series Geared DC Motor

Geared DC 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 bidirectional variable speed capability while the gearhead utilises a multistage 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.

Mclennan holds stock of various configurations in the UK for immediate delivery. For technical assistance and details of value added assemblies, including gearboxes and wiring / connector options please contact our sales and applications support team.
