5.2 General presentation

5.2.1 Description
The EX range of servomotors are permanent magnet, brushless servomotors designed for explosive
atmospheres, suitable for speed setting and automatic position control. Their low rotor inertia means
that they are optimized to provide high torque and considerable acceleration. The numerous
applications include robotics, specialized machinery, handling, etc.
Gas servomotor: IP65 – motor for gaseous atmospheres. This motor is fitted with a lip seal
-
at the customer shaft end. ( We did not evaluated the motor for Class II dust atmospheres).
5.2.2 Codification
A servomotor is defined by its electrical and mechanical characteristics, by its accompanying
accessories and by any customer specificity. This information is coded and entered in the "Type"
column on the manufacturer's plate for the basic codification; the specificities are entered in a
separate column.
