Session Topic: Synchronous PM Linear Motor Motion Technology

The synchronous PM linear motor became popular in the early ’90s as NdFeB magnets entered the market as substitute to SmCo magnets. This presentation will show real world applications of linear motors in various industries and compare synchronous PM motors with other types of drives such as ballscrews, belts, rack and pinion.

Also included will be some basic principles of calculations and sizing of linear motors and estimates for service life. Price level relative to other types of drives will also be covered.

Understanding price, performance, and service life comparison for synchronous PM linear motors may push users of more conventional drives to use instead linear motors because they offer significant advantages for a reasonable cost.
