Interroll introduces new oil-free drum motor

Already back in 2010 Interroll introduced the first oil-free drum motors. Since then, thousands of oil-free motors have been installed and are currently in use as a proven solution for many applications, in particular in the food industry. The oil-free drum motors now being introduced into the market are drum motors based on the new and improved Interroll Drum Motor Platform that has been on the market since 2017. Synchronous oil-free drum motors are by nature very efficient, which means less heat losses and a much higher power density, as opposed to asynchronous oil-free drum motors which are prone to overheating and power reduction and therefore loss in torque.

Compared to standard drum motors, the oil-free motor's performance is only minimally impacted by the different type of lubrication. Also, compared to a standard asynchronous motor, oil-free synchronous motors are stronger and better performing. But they require a frequency inverter and speed and torque are slightly reduced compared to a standard synchronous motor lubricated with oil. However, high-speed applications are still possible if the belt pull force is sufficient. This is also true for low-speed applications. Typical oil-free motor applications include transportation and packaging of lightweight goods such as candy, chocolate or pralines.

No leakage issues in sensitive production processes

Food manufacturers who have to comply with certain restrictions regarding food contamination benefit from this new option. Oil-free drum motors can be used for any application where the belt moves slowly (i.e., when the production process is in steps and accuracy is of paramount importance, like portioning and cutting for instance). When installed correctly, Interroll Drum Motors have no leakage issue. The oil-free drum motor makes the entire production flow safer as it eliminates any potential risk of oil contamination. It works well in cool temperatures, which are often a requirement in the food manufacturing sector. In certain industries such as fish processing, the European Hygienic Engineering and Design Group (EHEDG) recommends the use of oil-free motors.
