Highest efficiency with the smallest footprint
The ideal speed regulation solution for high-speed rotating equipment that saves energy and reduces CO2 emissions, the VECO-Drive, achieves this high operational efficiency by operating an electrically controlled superimposing planetary gear with frequency-controlled servo motors. As a result, a small amount of rated power ensures a record efficiency of more than 97%.

How the VECO-Drive works
Motor start
Direct online start (type RE)
Direct online start with VECO-Drive RE
The main motor is started directly online (DOL). Simultaneously, two servo motors accelerate the driven equipment smoothly, thus ensuring a rapid start-up and a reduced main motor load.
Soft motor start (type REC)
Soft motor start with VECO-Drive REC
This type uses two servo motors as an alternative to a direct online start. Large voltage fluctuations are avoided using the two servo motors as soft starters; this is highly recommended when large drives are connected to a weak grid.

In February 2020, the first two VECO-Drive units were successfully commissioned and put timeously into commercial operation. Processes have been running smoothly and efficiently at a thermal power plant in Guangzhou, China, with all tests onsite passed with distinction and fulfilling the customer’s expectations.
Currently, the two VECO-Drive units drive the boiler feed pumps and form part of an energy-saving transformation project.
