The Problem: A major airline manufacturer needed to eliminate the shaft seal for rotary feedback sensors in hydraulic actuators.

The Solution: Exploiting the solid rotor of the Rotasyn resolver, Admotec develped a unique “canned- rotor” resolver which allows the rotor to operate directly in hydraulic fluid. This unique product solved the shaft seal problem and lead to significantly lower maintenance costs.
 

The Problem: A major diesel engine manufacturer wanted to measure the torsional twist of the cam shaft during operation in a truck engine.

The Solution: Admotec engineers designed a custom split ring magnetic encoder that allowed installation directly on the cast and ground cam shaft as well as operation in hot engine oil. The benefit to the engine manufacturer was improved cam control, improved engine control and lower pollution levels.

The Problem: A large nuclear facility was experiencing continuing early failure of traditional feedback resolvers in the highly demanding conditions of the nuclear control system.

The Solution: Admotec recommended the variable reluctance, solid rotor Rotasyn resolver with a mean-time-between-failure double that of traditional resolvers. Operating almost 100 times longer than the previous resolvers, the Rotasyn significantly lowered maintenance costs and provided savings in the amortization of control equipment.

The Problem: A major printing equipment manufacturer needed to accurately measure the drum position in a sophisticated offset plate setter. A traditional optical encoder coupled to the drum produced cyclical errors due to the coupling.

The Solution: A custom magnetoresistive encoder was able to mount directly to the imaging drum, thus eliminating the coupling error. As a result, the accuracy was greatly improved, set-up and adjustment times were reduced and higher quality printing plates were produced at lower cost.

The Problem: A major manufacturer of torque flanges used in automotive dynamometers and powertrain test stands was experiencing early failure of their optical encoders.

The Solution: A standard Admotec large bore (200mm) encoder was incorporated directly into the torque flange, providing a compact, reliable speed-sensing solution. Operating at up to 10,000 rpm, these encoders provide accurate speed and position information at high temperature in the presence of dirt, grease, and oil.
 

The Problem: The extreme heat and harsh conditions of steel plants frequently cause optical encoders to fail.

The Solution: Admotec engineers, working with a major encoder manufacturer, designed an insert-molded large-bore magnetic encoder wheel and magnetoresistive sensor to the demanding specifications of the customer. The result: encoder life more than doubled while downtime and maintenance costs were greatly reduced.
