    What exactly is a "linear motor":

    I am told its different from a servo or stepper motor, and allows for high speeds. CAn somebody explain, what IS it?

    I've had several since 1999 but have settled on my beloved 2001 Litespeed Tuscany and my latest, a 2013 Cannondale CAAD 10.

    Most electric motors are rotary meaning that well, they're used to provide a rotational force. A linear motor is simply a motor that provides direct translational force. Think of something like a railgun.

    Oh so you dont need a leadscrew or anything to conver the rotational force into thrust? No wonder these things make serious speed

    Correct. Nothing is rotating. Your coils are lined up along a single axis. A popular application is in positioning subsystems.

    Some gear driven actuators are considered linear motors. For example, these

    Here's a fine example of a "linear motor" with an external ejectable armature..
