Drums and drum motors

You can send the drum motor to us for assessment. In many cases involving minor faults, the motor can be refurbished.

By coating the pulley with NBR rubber friction lagging (hardness 60-80 Shore A), you increase friction and power transmission efficiency.

Dimensioning depends on the load and the minimum pulley diameter of the conveyor belt. A good starting point is the diameter of your current conveyor setup.

Typically, the oil does not need to be changed. However, if necessary due to specific conditions, it can be drained and replaced via the plug on the end flange.

The main advantage is increased traction, requiring less power to drive the belt. It also allows for lower belt tension without the risk of slipping.

A drum motor is a self-contained drive unit with an internal motor, gearbox, and bearings integrated into a cylinder. A gear motor is mounted externally, either directly to the drive pulley or via transmission, which requires more space.

Drum motors are ideal for harsh environments with high levels of dust or grit, and where the equipment is subject to continuous freshwater washdowns.

You should inspect the shaft seals for mechanical wear or damage. Exposure to harsh chemicals can also degrade the seals over time.

Overheating can occur when high power usage is combined with low speeds or a dirty belt. The belt should cover at least 70% of the drum surface. If temperatures get too high, the built-in thermal protection will trip.
