High-torque drive

In addition to the electromechanical drive with belt or WAP gearbox and the hydraulic drive, the high-torque drive is a powerful drive option for WEIMA shredders that has proven itself with customers all over the world.

The high-torque drive used by WEIMA comes from Baumüller. As a specialist in the recycling sector, WEIMA relies on close cooperation with Baumüller, a leading provider of innovative drive technologies. This partnership enables WEIMA to offer powerful and reliable shredding solutions for demanding applications.

When shredding hard plastic parts, for example, enormous forces are exerted on the shredder. To ensure that the machines are constantly operational, the key components must be particularly robust. This is where the high-torque drive from Baumüller shines: there are fewer wear parts, as there are no hoses or gears.

Robust technology for maximum service life

The high-torque, multi-pole synchronous motor is produced in Germany and is characterized by its insensitivity to foreign bodies. Without a gearbox, the drive withstands shocks and vibrations and therefore has a particularly long service life – even when shredding challenging material flows. In addition, a coupling between the rotor shaft and drive protects the motor from damage and can stop the rotor immediately if foreign objects enter the cutting chamber. The torque and speed can be precisely adjusted via a frequency converter to achieve optimum results in terms of throughput and quality of the shredded material.

“The biggest advantage of the motor is its energy efficiency.”

Low energy consumption thanks to direct drive

By using direct drive technology, energy consumption can be reduced by up to 30 percent. In addition, the drive is very easy to regulate and control. As the speed decreases, the torque increases – an enormous advantage for the shredding process. The low noise level also speaks in favor of the drive from Baumüller.

Belt drive for optimum power transmission

A belt is used for the transmission of the direct drive, which transfers the power to the rotor and thus drives the cutting unit. Due to the connection of the rotor shaft via the belt, the Baumüller motor must be able to absorb radial forces of up to 40,000 N. This can be easily guaranteed thanks to a special bearing and the corresponding validation based on vibration measurements. In this way, vibrations can be compensated for and maintenance costs greatly minimized. The high-torque motor is ideal for shredding systems due to its good concentricity properties.

Innovative drive concept: New development with Baumüller and DESCH

The long-standing WEIMA partner Baumüller and the drive specialist DESCH have jointly developed an innovative high-torque drive. This combines the powerful high-torque motors from Baumüller with the robust direct drive from DESCH. The new drive technology significantly increases the efficiency and reliability of the shredders. Thanks to direct power transmission and high torque, it delivers optimal performance, especially when processing demanding material flows.
