Linear Motor Magnet Assembly

Dynamic performance
Applications for linear motors demand a variety of dynamic performance levels. The choice of a motor will be determined by the details of a system's duty cycle, as well as the peak force and maximum speed:
An ironless linear motor (which has a very light moving element containing no iron) is often used in applications with a light payload that call for extremely high speed and acceleration. When the speed stability must be less than 0.1%, ironless motors with air bearings are preferred since they have no attraction force.

Wide force-speed range
Direct drive linear motors may operate at high velocities as well as stalled or low velocities and deliver high force. As eddy current losses become a limiting factor in technology, linear motors can achieve very high velocities (up to 15 m/s) at the expense of ironcore motors.
Linear motors achieve very low ripple velocity regulation. The force-speed curve on the corresponding data sheet shows how well a linear motor performs over its velocity range.

Easy integration
Largely adaptable to most applications, linear motors come in a variety of sizes.

Lowered ownership costs
Mechanical transmission components like leadscrews, timing belts, rack and pinions, and worm gear drives are not required when the payload is directly coupled to the motor's moving section. In a direct drive system, there is no contact between the moving parts, unlike brushed motors. As a result, there is no mechanical wear, which leads to high reliability and a long lifespan. Less mechanical components mean less maintenance and cheaper systems.
