RE3620
Size 15 Frameless Resolver 36mm (1.5″ or 36mm OD)
The Micronor RE3620 series frameless Brushless Resolver provides high performance in measurement and feedback applications where traditional resolvers fail – high speed, vibration, shock and radiation environments. This resolver is designed for the most demanding harsh environment applications – including Aerospace, Space, Automotive, Marine, Submarine, Radiation, and Downhole.
The REXXXX series incorporate a proprietary solid rotor design with no windings. Hence, the resolver has only half the number of windings of a traditional brushless resolver, along with significantly increased reliability. The solid rotor allow operation with traditional oils or other liquids.
