Gericke, Regensdorf, Switzerland, reports that its established GMS mixers are now available with a new, very efficient drive, based on a permanent magnet motor. In these motors, the magnetic field is on one side created by a permanent magnet, which offers several key advantages. The delivered torque is constant over the entire speed range, which makes these motors ideal for batch mixers that start and stop frequently.

Since the magnetic field only needs to be built up on one side, the efficiency of the motors is significantly higher than that of asynchronous motors. The international energy rating for such a motor is ‘ultra premium efficiency’ (IE5). In addition to the higher rating, the high torque that can be delivered also indirectly reduces energy consumption, as the motor does not have to be oversized for the start-up.

Space limitations are often encountered in a production plant, especially when an existing installation needs to be updated. The new drives allow for a much more compact design, which provides an advantage when planning layout of production plant.

Noise emission can be very annoying, even in production environments. The new motors are significantly quieter thanks to the flattened peak current, especially during start-up, when any annoying whistling sound is eliminated.

The intelligent frequency inverter allows direct installation and integration into the PLC with a fieldbus interface, avoiding the need for multiple installation and commissioning times. The frequency inverter records the data accurately, which enables precise diagnosis and is entirely in line with Industry 4.0 and Internet of Things standards.

The GMS mixers are now equipped with these motors as standard on all larger models. www.gerickegroup.com
