3.2 General presentation

3.2.1 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 optimised to provide high torque and considerable acceleration. The numerous
applications include robotics, specialized machinery, handling, etc.
There are two types of servomotor:
- Gas servomotor: II2 G EEx d IIB T4 IP64 – motor for gaseous atmospheres. This motor is
not fitted with a lip seal at the customer shaft end.
Gas/dust servomotor: II2 GD EEx d IIB T4 IP65 T135°C – motor for dusty, gaseous
-
atmospheres. This motor is fitted with a lip seal at the customer shaft end.
3.2.2 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.
