Two-in-one motor with integrated frequency inverter

By using frequency inverters, plant and machine manufacturers can get even more out of their motors. This is because they allow universal drive machines to be operated flexibly. With this in mind, KEB Automation has introduced asynchronous geared motors with integrated frequency inverters.

When it comes to targeted starting and stopping, smooth starting and braking, or operating the motor at different speeds, frequency inverters are the first choice. Drive controllers from KEB Automation are at home in machines and plants across the world, where they ensure smooth drive operation.

In addition to the previous range of these central drive controllers, decentralised solutions are also now available. Specifically, the MU series inverters are designed so that they can be used as an integral component of KEB geared motors with a power range from 0.37 kW to 7.5 kW.

Daniel Lehmann, product manager for motors at KEB Automation, explains the benefits of the motor-inverter combination: The inverters are mounted directly on the motor as decentralised devices. This saves important space in the control cabinet. Users also benefit from high performance and easier installation.

Depending on the performance requirements, the application and the customers needs, the KEB portfolio offers a customised solution. We offer our gear units and motors according to the modular principle. The same applies to motors with integrated inverters. Here, asynchronous geared motors can be combined with different frequency inverters and technical specifications, adds Lehmann.

Flexible, custom drives

The integrated frequency inverters are available in ten sizes for mains voltages of 230 and 400 V. The motors can be efficiently designed for different operating points (87, 100 and 120 Hz). This means that customised drives can be put together flexibly. Short cable lengths also prove to be particularly practical in daily operation. In addition to the drive task, the 2-in-1 motors can also take on control and monitoring functions and can be integrated into centrally controlled systems.

Motors with integrated inverters are in demand in intralogistics, textiles, wood and metal processing machines. Food and packaging machines also benefit from the fact that the inverters are protected by a separate housing for use in the field. The inverters have a high IP protection class and are designed for ambient temperatures of up to 40 degrees Celsius. EMC limit class C2 in accordance with DIN EN 61800-3 ensures smooth operation, with motor installation and standard switching frequency, says Lehmann.
