Inductive resolvers are considered more rugged than rotary encoders for use in adverse operating conditions involving extreme temperature (up to 220‘C), high shock, vibration or dirty environments. Shielded, spaced support bearings found in our resolvers provide up to 10x the life of duplex bearings. Tooth-wound models cut electrical error 50% and brushless resolver models eliminate components that can limit life. Available in housed and frameless varieties.
Housed-Brushless Resolvers Our brushless construction uses a rotary transformer to pass the reference signal to the rotor. This design eliminates the normal brushslip ring sliding contact used in conventional resolvers. Since the brush and slip ring are life limiting components and can be a source of noise in harsh environments, the transformer coupled units enhance reliability and performance.
Our brushless resolvers are the ideal position feedback transducer for brushless motors, robots and direct drive motors in precision rotary platforms and similar servo applications. They are rugged, reliable, provide absolute position information and are able to operate at 155‘C and are impervious to most particulate and liquid process contaminants.
