Power Trasmission & Motion Control

Gear reducer

Designed for dynamic and continuous high-speed applications, the SP High-Speed Gear Reducer can run as fast as 4,500 rpm in continuous operations. The unit mounts directly to servo motors running continuous duty cycles, and acts as a heat sink. The cooler temperature lets the motor run faster and longer.

Miniature motors

This company's 22BC brushless motor has been redesigned to offer a reported increase in performance and life. Available in 50W (long) and 15W (short) versions, the motors have repositioned bearings which are said to provide noise reduction, while the motor's magnetic circuit has also been redesigned. Applications include hand tools, medical respirators, medical pumps, and small actuators.

Motion controllers

Integrated Ethernet technology lets users place E-Series Motion Controllers adjacent to motors and I/O signals, reducing wiring complexity. A single controller acting as the master device can receive all motor commands from the host computer and then pass these commands to multiple slave E-Series controllers. The DMC-3425 is the first member of the series, and can control two servo motors.
