maxon motor DC linear actuator

maxon motor has released a 6 mm micro linear positioning drive with internal gearing. Micro DC motor linear positioning systems are suitable for applications that require accurate positioning and high forces while maintaining minimal weight and a small footprint; eg, syringe pump actuation and lens or sensor adjustment in a production or laboratory environment.

The linear speed, length and forces can be controlled and adjusted by combining a suitable brushed or brushless DC motor, encoder and motor drive electronics. Up to 11 N continuous and 15 N intermittently can be achieved with linear speeds of 25 mm/s. With a linear actuator, thrust bearing system and planetary gearhead in one assembly, the product weighs only 2.9 g. This makes it suitable for specialist robotic applications.

The device is available in two versions: a ceramic version for high efficiency and longer lifespan; and a metal version which is more cost effective for less demanding applications.
