Problem 1
A large aircraft supplier wanted a rotational angle sensor – an Aerospace Resolver – without a shaft seal for hydraulic actuator position feedback in the range of ±30°.
Aerospace Resolver for highly precise angle measurements
The Solution: The Solid-Rotor Rotasyn Resolver from Admotec
Using the solid-rotor Rotasyn aerospace resolver, Admotec developed this unique “encapsulated rotor” resolver, which enables operation of the rotor directly in the hydraulic oil. This solved the shaft seal problem, resulting in significantly lower maintenance costs.
Problem 2
A large aircraft supplier wanted a sensor without shaft seal to detect rotational speed in a hydraulic actuator.
The Solution: Rotasyn Aerospace Resolver from Admotec
Using the solid-rotor Rotasyn resolver, Admotec developed this unique “encapsulated rotor” resolver, which enables operation of the rotor directly in the hydraulic oil. This solved the shaft seal problem at high speeds, significantly lowering maintenance costs.
Problem 3
A large aircraft supplier sought a resolver for commutation of a PM motor with the highest possible Mean Time Between Failure (MTBF)
The Solution:
Using the solid-rotor Rotasyn resolver, Admotec developed this unique resolver with half the usual number of coils. This solved the reliability problem, resulting in a significantly safer system.
