Linear motor - Wikipedia

A linear motor is an electric motor that has had its stator and 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 ...

How do linear motors work? A simple introduction

15/7/2019· How linear motors work Photo: An ordinary electric motor is all about rotation: the rotor (the coils in the center) turns inside the stator (the outer magnetic case). In a traditional DC electric motor, a central core of tightly wrapped magnetic material (known as the rotor) spins at high speed between the fixed poles of a magnet (known as the stator) when an electric current is applied.
