Air motors: the features for the paper industry

An application case and Fiam solution

Features of motors for this sector:

- A key, essential requirement is the absence of electricity as a power source to prevent the risk of fire. ATEX certification on request

- Special galvanic treatment on inner workings to increase corrosion resistance where the use of lubricated compressed air is not an option

- Power range: 150 to 800 Watt

- No-load speed: from 40 to 15,000 rpm

- Torque values: from 1 to 90 Nm.

Below a case study about integration in solution for the paper industry

Manufacture of paper-making machinery incorporating air motors required to drive the cleaning rollers whose job is to remove ink: the motors are required to have the following features:

- compressed air supply as electric motors heat up, increasing the risk factors for manufacturing environments (such as the hazard constituted by electric cables)

- must drive heavy rollers and cope with particularly heavy-duty work given the repeated starting and stopping over the course of various work shifts

- different sizes to suit the different rollers to be driven, which are often small.

Our solution

28M motors, with a power rating of 280 Watt, designed with plenty of scope for customizing in terms of size, with a great ability to withstand locked-rotor torque to provide continuous service when starting under load, and suitable for frequent use in start and stop mode.
