Harowe® Resolvers Selection Guide Harowe® Resolvers Selection Guide Able to withstand the most challenging environments, Harowe Resolvers can operate at temperatures of up to 200°C, and have unmatched mechanical shock and vibration specs. Designed with durability and performance in mind, Harowe Resolvers are guaranteed to reduce failure rates and extend life. The shielded, spaced-support bearings provide 10x the life of standard, duplex bearings, while toothwound models reduce electrical error by 50 percent. Brushless models eliminate the need for multiple components, which can dramatically limit life. As the most durable and rugged feedback option, Harowe Resolvers are the perfect choice for applications that operate in conditions involving extreme temperature, high shock and vibration, and dirty environments.
