Linear servo motor is an actuator producing linear force or motion and is constructed from a linear motor and a linear feedback device such as linear encoder.

Linear servo motor is electrically equivalent to a rotary motor, so drive sees no difference between the two.  However, as drive parameters are entered for rotary motor only, they need some calculations to suit for linear motor.

==Configuration==
===Preparations===
Needed parameters of linear motor:
*Magnetic pole pitch (or pole pair pitch)
*Forcer winding specifications:
**Maximum currents: continuous and peak
**Inductance and resistance
**Thermal time constant (optional but recommended)

Needed linear feedback device parameters:
*Resolution (lines or pulses per millimeter)
===Conversion of parameters===
In this step we convert the values so that motor can be driven from a servo drive. The drive is made to believe that the linear motor is rotary motor, so we need to figure out the equivalent rotary motor parameters. This example works with [[Granity]] software.
