linear motors

Linear motors have earned a reputation as highly precise and efficient alternatives to conventional rotary-to-linear transmission systems. Find out why, plus learn about the ultra-precise and energy-efficient linear shaft motor.
To fully appreciate the chief advantages of linear motors, it is helpful to compare them to ballscrews, another high-precision rotary-to-linear transmission system. Although typical ballscrews are roughly 90% efficient, servomotor efficiency (typically 75% to 80%) — plus losses introduced by the coupling and gearbox — reduces the power supply going toward actual work to 55% in some cases. In comparison, typical linear motors drive loads directly, which boosts overall efficiency.
