Device description

Linear Motor

Direct linear electric motor producing translational force without mechanical conversion from rotation.

A linear motor generates thrust directly along the motion axis without a ball screw, belt, or gearbox.

Primary mechanical characteristics are continuous and peak linear force and maximum travel speed.

Electrical characteristics include peak current, winding resistance and inductance, and the relevant motor constants.

Depending on the system, the motor may use external or integrated position feedback and additional braking devices.

Selection considers required force, speed, thermal conditions, feedback system, installation geometry, and compatibility with the servo drive.
