LOW-COST BRUSHLESS PANCAKE RESOLVERS
Rugged, reliable - ideal for demanding environments. Brushless resolvers provide accurate position and velocity feedback as well as commutation in precision equipment, without the structural or temperature restrictions imposed by other electronic feedback devices. They are resistant to the shock and vibration levels often encountered in industrial and instrument applications.
These low cost brushless resolvers are available in standard sizes or with custom modifications. Our Engineering Department is available for consultation to help tailor a brushless resolver to fit your needs.
