The design of the Linear Shaft Motor allows you to replace traditional linear mo-

tion systems, such as a standard ball screw, with the Linear Shaft Motor and achieve

higher speed and resolution.

To achieve the highest performance with the Linear Shaft Mo-

tor system, the entire system structure must be optimized.

Be aware there are various design considerations which are

somewhat different from traditional servo system practices. These

are the main components needed to make a Linear Shaft Motor

system, as well as factors to consider when designing a system.

To configure a system using the Linear Shaft Motor, the following peripheral

devices are required:

A. Linear Shaft Motor

B. Servo Driver

C. Linear encoder (optical or magnetic)

Item D (Linear Guide) is a necessary part of a system, but consideration must be

given to the application, demand specifications, environmental

conditions, and which will be moving--the forcer or the shaft.

The other items, E through G, are optional and will need to be selected depend-

ing on the application.

Configuring the Linear Shaft Motor

Steps to putting together a

Linear Shaft Motor System

Choose the Linear Shaft

Motor based on force and stroke

requirements.

Choose the shaft supports

based on design and motor

specifications.

Choose the linear guide

(bearings) based on

cost and smoothness

(performance) constraints.

Choose the linear encoder to

achieve the required position

resolution.

Choose the servo driver to

match the power requirements

of the Linear Shaft Motor.

Choose the OTL, limit

switches/other components and

assemble the Linear Shaft

Motor system.
