The PRA worm gear motor can be supplied with input flange or adapters with coupling.
Flanges are applied in all PRA line, and the motor’s type are IEC (FF” B5” or “C”Din “B14”).
The adapters with coupling are used in the model’s PRA02, PRA03 and PRA04, with type motor’s IEC (FF “B5”).
The direct mounting with motors is made with input flanges or adapters with coupling, ensuring perfect alignment between the motor and reducer.
To define the perfect assembly with electric motors in necessary to inform the frequency, electric tension, polarity, if there is brake system, and other characteristics.
