Motor Designs To Survive Hostile Environments

From Empire Magnetics Inc.

A new generation of step motors is allowing motion control applications to prosper where they were previously impossible or, at best, very difficult. The reason? Previous step motor designs were developed for the relatively "benign" conditions in a factory. New step motor designs -- specially developed for motor-hostile environments -- can reliably withstand the effects of radiation, underwater operation, vacuum operation, and extremely high and low temperatures, among other conditions. Accordingly, these motors are the key to a wide range of new motion control opportunities.

Products & Services
DC Motors
DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors.
Brushless Motors
Brushless motors are synchronous electric motors that have a magnetically (AC induction) or electronically (DC) controlled commutation system instead of a brush-based mechanical commutation system.
DC Servomotors
DC servomotors are generally small and powerful for their size, and easy to control. Common types of DC servomotors include brushless or gear motors.
Stepper Motors (Rotary)
Stepper motors use a magnetic field to move a rotor in small angular steps or fractions of steps. They provide precise positioning and ease of use, especially in low acceleration or static load applications.
