Analog & Power: Resolvers Measure Speed, Position In Demanding Environments

The Harowe line of resolvers suits motor speed and position measurement where inherent durability is required. Frameless units range from size 10 to size 55, while housed resolvers range from standard-grade size 11 to heavy-duty, industrial-grade size 25. The frameless, brushless types feature tooth-wound construction with consistent windings that halve the electrical errors of competitive models. A size 15 frameless model costs from $65 to $260 each in low volumes. Availability is in two weeks from receipt of order.
