Resolvers – Robust Sensors for Accurate Performance in Tough Environments

The Smartsyn resolver is a robust analog angle sensor with very high accuracy and good reliability. Thanks to its robust design and high temperature resistance, it is suitable for challenging environments.

Smartsyn resolvers are used in all types of angle sensing in, among others, factory automation, automotive and construction industries, marine applications and the nuclear industry. The high accuracy makes it excellent for commutation of servo motors or angle sensing in rock drilling equipment.

Singlsyn is a variable reluctance resolver that is mainly used in applications where there is a need for extreme reliability and robustness. Thanks to its powerful design, the ultra-thin, analog angle sensor is suitable for installation in harsh environments with limited space. Singlsyn resolvers work well in traction drives for cars, trucks, trains, ships, heavy transport, forestry machinery and mining machinery.

The Singlsyn resolver is also extremely suitable for modern electromechanical servo control with electric motors, drive-by-wire and break-by-wire, where it replaces mechanical and hydraulic systems. The resolver can handle temperatures up to 155 ⁰C and speeds of up to 30,000 rpm in standard design. There are several sizes as standard, all with large hole diameters. In addition, the design and properties of the resolver can be highly customized to meet specific electrical and mechanical requirements.

Doublsyn is similar to Singlsyn as it is also thin and highly precise. It operates without any rotor windings and what distinguishes the Doublsyn is its high redundancy and that it has an additional copper winding in the stator, which offers increased reliability. It is noise resistant, making it suitable for harsh environments with demanding requirements.
