LML series low cost belt drive linear modules

LML series belt drive lineBelt drive linear modules LML seriesar modules from Smart Motor Devices are designed for precise linear motion of light loads with great value for money.

The main structure of the LML series linear module is a T-slot aluminium extrusion which takes the role of a linear guide and provides convenient mounting options. The moving carriage is connected to a timing belt which is driven by a toothed wheel on a stepper motor. The carriage rides on 4 polycarbonate rollers which ensure smooth, quiet motion. These have an adjustable preload to eliminate backlash and cross motion.

Linear motion is 40mm per motor revolution. This gives a resolution of 0.2mm per full motor step (1.8 degrees) which can be increased with an appropriate microstepping driver.

The LML series are available with three standard travel lengths and two motor mounting positions. Additional options such as custom travel, limit switches and built in drivers are available on request.
