MotiCont Introduces High Speed, Zero Cogging DDLMs

MotiCont, a manufacturer of motion control products, has introduced a new line of direct drive linear motors (DDLMs).

MotiCont's  DDLMs eliminate backlash and provide an economical solution for users requiring high acceleration, high speed, and long life. They are available in three off-the-shelf models. The compact DDLM-019-044-01 linear motor is only 0.75 inches in diameter and 1.75 inches. It has a stroke of 0.46 inches  and features 11 ounces of continuous force and an 34.8 ounce peak. The compact, longer stroke DDLM-019-070-01, linear motor is also only 0.75 inches in diameter but is 2.75 inches long. It has a stroke of 0.96 inches and features 10.1 ounces of continuous force and a 32.1 ounce peak.  For higher force applications the DDLM-038-051-01 linear motor is 1.5 inches in diameter and 2 inches long. It has a stroke of 0.375 inches with a continuous force of 3.1 pounds and a 9.9 pound peak.

These compact motors can be integrated into new and existing applications using threaded features on the front and rear faces of the motor, as well as each end of the shaft. The feedback devices, amplifiers and controllers are also available. 

Non-commutated, moving magnet motors have zero cogging and the light mass of the moving part allows for high acceleration/deceleration for higher throughput, and direct coupling to the load increases accuracy. All DDLM linear motors are also available with internal springs to retract the shaft to a home position in the event of a sudden shutdown.

Typical DDLM direct drive motor applications include: Automated assembly, component insertion, fluid dispensing, pick-and-place, robotics, wafer handling, sorting, valve and flow control, labeling, tension control, and laser machining in the processing, manufacturing, medical, inspection, metrology and other industries.
