LIM-TEC - Model Exlar Series -Electric Servo Cylinder
As the second largest global professional manufacturer of the roller screw actuator and the power transmission equipment, Exlar leads the linear industry to a new era with its multiple patents.
Exlar’s actuator combine the advantage of the Exlar’s roller screw technology and the T-LAM segmented technology to create the revolution of the linear actuator?Exlar’s special design integrates the stator with the roller screws, which are fixed evenly around the main screw in a planetary fashion and precisely machined on the inside surface of the actuator’s hollow armature. Linear motion is produced in synchronization with the armature rotation. Because this roller screw mechanism has an inherently larger cumulative contact surface, these motors have a much longer working life, and can handle heavier loads at higher speeds than is possible from a similarly sized unit built in around a ball screw system.
Exlar’s T-LAM segmented lamination stator technology delivers higher continuous motor torque than is available in traditionally wound motors. T-LAM technology consists of stator segments, each containing individual phase wiring for maximum motor performance meantime lower the level of the heat generation of the segmented stator. The elimination of the end turns of the stator and use of the thermally conductive potting removes the parts most susceptible for failure in a traditional stator.
The combination of the high precision components guarantees the high efficiency of the actuator. The mechanical time of the Exlar actuator is around 10ms, which is the leading level in the same industry. The positioning precision of the single nut roller screw can reach 0.05mm, with repetitive precision 0.01mm, while that of the double nut roller screw can reach 0.1um.The lifetime of the Exlar’s screw is 5-15 times that of the ball screw actuator in the same diameter.
