Linear Motors, efficient and reliable sources of linear force and motion, are the prime elements of modern electromagnetic propulsion systems, utilized in transportation and amusement rides applications.

Although the idea for the development of a Linear Motor originated about a century and a half ago, this technology experienced real growth only in the last five decades. These were the innovative years when progressive designers and manufacturers of propulsion systems recognized the true potential and practical advantages of Linear Motors. During this time Sherwood Electromotion Inc. (SEI) developed and introduced distinct products and services for the electromagnetic propulsion systems equipment.

Over the last forty years SEI has been involved in numerous diverse projects utilizing Linear Motors. Whether induction or synchronous, single sided or double sided, short stator or long stator, low voltage or high voltage, SEI’s technical expertise covers every type and variant of Linear Motor.
