The interest in frequency converters – also called VFD (Variable Frequency Drives) has been steadily increasing in many segments over the past few years. With good reason. Lower energy consumption, better control and more intelligent operation are just some of the advantages of an electric motor being driven by a frequency converter.
Now Hoyer’s customers can get a total solution with motor and frequency converter via the new product group: Hoyer Drives & Controls.
“We can see that the demand for total solutions with electric motors and frequency converters has matured among our customers over the past few years. The focus on energy optimisation has increased in the area of our core applications such as ventilation and pumps in particular. With Drives & Controls we have united our resources and competences and we can now give our customers optimal service throughout the entire process,” says CCO Ketil Vesterlund at Hoyer Motors.
Cooperation with leading manufacturers
On several occasions, Hoyer has worked together with strategic customers to select frequency converters and supply the respective motors as a total solution prepared for plug-and-play-installation. These projects have been supplied in cooperation with market-leading VFD manufacturers.
The experience gained from this is now forming the basis for Hoyer Drives & Controls. In cooperation with three selected partners– Schneider Electric, Danfoss Drives and Kostal Inveor, Hoyer is offering complete motor and VFD solutions that contribute to the customer’s supply chain – both technically and commercially. One example is fully integrated solutions that are ready for use on delivery. The motors are supplied with the correct cables, filters and plates for installation and the frequency converter has already been calibrated and phased in with the motor.
“Previously, our customers have needed to buy a motor from Hoyer Motors and a frequency converter from another supplier. This has meant them being responsible themselves for installing and testing the final solution. Now we can move those tasks further down the value chain and supply a total solution that is ready to run. Hoyer is the only contact point for ordering, delivery and running-in,” says Ketil Vesterlund.
Paving the way for intelligent solutions
At the same time, the increased use of frequency converters also helps pave the way for more intelligent solutions. Sensor data and feedback from the application can be gathered in the converter and used for autonomous operation and predictive maintenance. The increased focus on frequency converters and the close cooperation with the VFD manufacturers enables Hoyer to discuss new opportunities with the customers.
“By recording data via the frequency converter, a better insight into the application can be achieved. This provides better options for the different interfaces and applications to communicate with each other. We are also looking at Bluetooth solutions for motors without frequency converters. This kind of solution could, for example, send data directly to a smartphone when the person responsible for maintenance is moving around the engine room or production,” says Ketil Vesterlund.
Frequency converters provide full control and optimised operation
A frequency converter will often be the optimal solution for regulating the speed of an application driven by an electric motor. Using a frequency converter typically provides better and more effective control and at certain types of applications it can provide energy savings of up to 50 percent.
