Motor Technology: Tubular Linear Motors

 

 

The tubular linear motor has only two components, the rod and the forcer. This simple configuration for providing linear thrust is used as the base for all motion solutions.

Linear Electric Motors provide direct thrust for the positioning of a user's payload. They eliminate the need for a rotary to linear conversion mechanism. Eg. ball screw, rack and pinion, toothed belt.

This is an extremely efficient motor design. The armature motor coils completely encircle the stator magnets to ensure optimum use of stored energy. All the standard motors operate without any forced cooling. The benefits of linear motors are readily available to machine manufacturers throughout industry.

Products & Services
Linear motors generate force only in the direction of travel. They are capable of extremely high speeds, quick acceleration, and accurate positioning. Search by Specification | Learn more about Linear Motors
DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors. Search by Specification | Learn more about DC Motors
Motor coils are used with motors, generators, stators, and armatures. Learn more about Motor Coils
Rack and pinion drives use a rotational motor to affect linear motion via a rack and pinion combination. They are used frequently in long-travel applications, such as machine tool table positioning, that require high stiffness and accuracy.
