The PR worm gear motor can be supplied with input flange or adapters with coupling.
Flanges are applied in the models: PR 05, PR 06 and PR 07, and the motor’s type is IEC (FF “B5”).
The adapters with coupling are used in all the models. 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.
