Linear Motor

The construction of a linear motor is the same as a rotary motor but opened up and flattened out. Configuring a servo drive for a linear motor is identical to configuring a drive for a rotary motor.

A linear motor is made up of permanent magnets alternating in polarity and a moving carriage with three phases of coils. The direction of current through these coils magnetizes the phases north or south, which pulls or pushes it along the motor track respectively.

These motors are used for applications where precise and high speed linear motion is necessary, such as industrial 3D printers or AMC’s ball toss demos.
