Industrial working environments can be hard on position feedback transducers. Incremental rotary encoders are simple and cost effective in many motion control applications. However, encoders fail under extreme conditions such as high temperature, vacuum, radiation, or shock and vibration.
Brushless Resolvers Survive
Empire Magnetics makes resolver technology easy to apply with rugged motor-mounted resolvers and an easy to use resolver-to-encoder conversion module. Brushless resolvers and available with all Empire Magnetics motor products, providing shaft position information under harsh conditions.
Empire Magnetics mount optional size 11 resolvers on the back end of most Empire motor products, including gearmotors, and motors rated for submersion, vacuum, or radiation. Resolvers on environmental motors carry the same rating as the motors.
