Hiwin Shaft Motors - LMTD series

The HIWIN LMTD series: LMTD = Diameter of stator = 42.7mm, Peak = 548N - 1096N, Continuous = 137N - 274N

Linear Shaft Motors - LMTD series

The HIWIN rod-shaped linear motor has a variety of size series, with complete specifications, and easy installation. The maximum peak force for this motor is up to about 2570N. It complies with international safety CE certification, has dustproof and a waterprood IP66 rating. Using direct drive technology, on other mechanical conversion components arr needed to acieve linear tranmission, with high-speed, no cogging and low velocity ripple along with other characteristics including; excellent dynamic performance, no wear, zero backlash, and easy maintenance. Compared to traditional mechanical linear solutions, the motor effectively enhances machine equipment production capacity and reduces maintenance costs to meet the needs of high-precision positioning control and smooth operation applications such as high-speed light-load automation equipment, dust-free environment, automation equipment, panel equipment, optical inspection equipment, tool line cutting equipment, scanning electron microscope equipment, medical automation and other industries.
