Nippon Pulse Introduces L250SS Linear Shaft Motor

Jul 06, 2010

Nippon Pulse has announced the release of its newest linear servomotor, the L250SS Linear Shaft Motor. The new SS-series is highlighted by a forcer that is 50mm in length, significantly reducing the length that had been offered on the standard L250 motor. The standard L250 forcer length ranges from 120-210mm.

By reducing the size of the forcer to just 50mm, Nippon Pulse has provided the user a longer range of movement than has previously been available.

In addition to a greater motion range, the SS series also features a large non-critical air gap, up to 5mm, which allows easier and more flexible machining and installation. Users of the SS series do not have to be as precise with alignment and have flexibility over the length of the stroke. The larger air gap is also beneficial in applications that may cause build up on the shaft, extending the time in between needed maintenance.

Other features of the SS series include available stroke lengths of 100~3,750mm, continuous forces of up to 24N, and a peak force of up to 94N. The motors also feature a back EMF of up to 4.5 V/m/s and rated forces of up to 17N.

Nippon Pulse's Linear Shaft Motor has three basic concepts. It is simple, consisting of only a magnetic shaft and a forcer. The motor is also high precision, taking advantage of its ironless make-up to offer zero cogging, while giving complete stiffness. Being non-contact, the shaft motor has a non-critical air-gap that eliminates variation in force over the entire stroke of the device.

Nippon Pulse America, a fully-owned American subsidiary of Nippon Pulse Motor Co., Ltd of Tokyo, Japan. Nippon Pulse offers various controllers (boards and chips), drivers (boards and chips), and motors (tin-can, hybrid and linear servo) to cover almost any motion application.
