OverviewThe explosion-proof dynamic brushless Moog ExD servo motor (Explosion Proof Dynamic Brushless Servo Motor) is an AC synchronous motor specifically designed and certified for use in potentially explosive environments. The ExD series complies with ATEX and IECEx standards and is built from robust components able to withstand demanding thermal conditions. High-reliability resolvers, sealed lifetime-lubricated ball bearings, precision-balanced rotors (ISO 1940 Grade G 6.3) and an IP67 enclosure design ensure maximum product service life.
