Direct-drive linear motors for robotics, automated assembly, and flow control introduced by MotiCont
VAN NUYS, Calif., 19 Dec. 2014. MotiCont in Van Nuys, Calif., is introducing direct-drive linear motors (DDLMs) for motion control in robotics, automated assembly, wafer handling, valve and flow control, in the processing, manufacturing, medical, inspection, metrology and other industries.
The motors can help eliminate backlash and provide an economical solution for users requiring high acceleration, high speed, and long life, MotiCont officials say.
They are available in three off-the-shelf models. The compact DDLM-019-044-01 linear motor is 0.75 inches in diameter and 1.75 inches long.
It has a stroke of 0.46 inches, and has 11.0 ounces of continuous force and 34.8 ounces peak. The longer-stroke DDLM-019-070-01 linear motor is 0.75 inches in diameter but is 2.75 inches long. It has a stroke of 0.96 inches, and has 10.1 ounces of continuous force and 32.1 ounces 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 9.9 pounds peak.
These compact motors can be integrated into and existing applications using threaded has on the front and rear faces of the motor, as well as each end of the shaft. The feed-back devices, amplifiers and controllers also are available.
Non-commutated, moving magnet motors have zero cogging, and the light mass of the moving part allows for high acceleration/deceleration for high throughput, and direct coupling to the load increases accuracy. All DDLM linear motors also are available with internal springs to retract the shaft to a home position in the event of a sudden shutdown, and they can be quickly customized to meet specific needs.
