Meaning and Definition
An electric motor that produces force in a straight line (linear motion) directly, without needing gears or mechanisms to convert rotary motion.
A motor whose stator and rotor are 'unrolled' into a flat configuration, generating electromagnetic propulsion along a linear path. Used in applications requiring precise, high-speed linear movement, such as in maglev trains, industrial automation, and precision machining.

- Confusing it with a general 'linear actuator' (which may use a screw or piston, not electromagnetic principles).
FAQ
Frequently Asked Questions
No. A linear motor is a specific type of linear actuator that uses electromagnetic force. 'Linear actuator' is a broader term for any device that creates motion in a straight line, including hydraulic, pneumatic, or mechanical screw types.
They are used in applications requiring fast, precise, and smooth linear motion, such as in maglev trains, CNC machines, semiconductor manufacturing equipment, and high-speed packaging machinery.
Advantages include higher speeds and accelerations, greater precision and repeatability, minimal maintenance (no mechanical contact for force generation), and reduced mechanical noise and backlash.
Yes, but it requires a braking or locking mechanism to hold the load in position when power is off, as electromagnetic force is only present when powered, unlike a screw which can be self-locking.
An electric motor that produces force in a straight line (linear motion) directly, without needing gears or mechanisms to convert rotary motion.
Linear motor is usually technical in register.
