[[File:Linearmotorprinzip.png|thumb|right|Synchronous linear motors are straightened versions of permanent magnet rotor motors]]
A '''linear motor''' is an [[electric motor]] that has had its [[stator]] and [[rotor (electric)|rotor]] "unrolled", thus, instead of producing a [[torque]] ([[rotation]]), it produces a linear [[force]] along its length. However, linear motors are not necessarily straight. Characteristically, a linear motor's active section has ends, whereas more conventional motors are arranged as a continuous loop.
A typical mode of operation is as a [[Lorentz force|Lorentz]]-type actuator, in which the applied force is [[linear equation|linearly proportional]] to the [[electric current|current]] and the [[magnetic field]] <math>(\vec F = I \vec L \times \vec B)</math>.
