Moticont has added two linear motors to its SDLM Series of high-speed direct-drive linear motors. These compact drives with a 1.0 in. (25.4 mm) stroke are just 1.00 in. (25.4 mm) in diameter and 3.75 in. (95.3 mm) long. These direct-drive linear motors feature resolutions of 5 µm (0.000197 in.) and 1.25 µm (0.000049 in.) The integral, linear optical quadrature encoder is directly connected to the shaft for the greatest possible accuracy. Each motor features a continuous force rating of 20.1 oz (5.82 N) and a peak force of 66.3 oz (18.4 N). This motor is designed with a larger air gap of 0.059 in. (1.5 mm). The larger air gap lets the motor be used for applications where excessive side play or tilt is required.
The non-commutating SDLM-025-095-01-05 (5 µm resolution) and the SDLM-025-095-01-01 (1.25 µm resolution) linear motors have quiet, long-life, plain linear bearings, a non-rotating shaft, pre-drilled and tapped mounting holes, and threaded (internal) ends of the shaft for easy integration into new and existing applications. These low-cost direct-drive motors are coupled directly to the load providing high acceleration and speed with zero cogging and no backlash as with other drive systems such as ballscrews, gear, and rack and pinion drives.
Both linear motors are also available as a complete plug-and-play linear motion system with a matching motion controller.
