Parker - EX Series - Explosion Proof (ATEX Zone 1) Brushless Servo Motor

The EX series is a range of permanent magnet explosion-proof brushless servo motors designed for use in explosive atmospheres. Featuring robust explosion-proof housings, EX synchronous servo motors are capable of bearing internal explosions with no risks of propagation to the neighbouring environment. The EX series of servo motors are characterized by excellent motion quality, dynamic acceleration/deceleration capabilities and high torque output over a wide speed range. Various winding variants and numerous options are available to offer maximum flexibility. Two versions are available, conforming with either the North American or European safety standards.
