What makes Vostermans motors unique?

2 minutes reading - published on November 6, 2020

For decades now, our Multifan, EMI and Mf-Flex motors have been known as very robust and reliable. The motor’s proven concept has remained unchanged over the years. However, the configurations have been further refined in order to keep up with
the latest guidelines regarding energy efficiency. But what is it exactly, that makes our motors so special?

Developed for the agricultural market

Vostermans Ventilation is an organization that has changed considerably from the past. 1952, when founder Toon Vostermans was at the start of what is now Vostermans Companies, the means to export internationally were not yet available. As a result, he started looking for new customers in the Venlo area (in the Netherlands). At the time, Venlo was a highly developed agricultural area. Vostermans quickly became a specialist in this sector, and the fans were attuned to the demands of the market. The specialization in this sector, and the robust products required for this, can still be seen in our product portfolio now, almost 70 years later.


No compromises on quality

We understand that ventilation in the agricultural sector is essential for the animal
welfare of livestock. This is why we cannot afford to compromise on the quality of
motors. We opt for the best bearings suitable for ammonia-rich, moist and warm
environments, and opt for copper wire with extra protective layers. While unnecessarily robust in many cases, it is necessary in others. It allows our motors to meet even the strictest certifications, such as UL and CSA, and to comply with insulation class F.

A Dutch heart

Vostermans motors are developed and produced in the Netherlands. Our R&D team
is continuously working on further development, and production is constantly being
expanded and upgraded. In this way, we create the means to further reduce tolerances and continuously improve the efficiency of the motors. As a result, our motors are among the best on the market.

An open motor

Our motors are IP55 certified, which means that it’s impossible for large amounts of
spray water or dust to enter the motor. Because of condensation alone, however, about 0.5 liters of water flows through the motors annually. It is therefore essential that moist air can escape from the motor. We have developed special drainage channels for this purpose, which considerably extends the service life of our motors.

Customization is the standard

While it is more common for portfolios to consist of a number of standard motors, we believe that customization makes the difference. For our fans we can choose from hundreds of motors with different characteristics. It allows us to create the ideal motor – impeller combination. And when this combination is in balance, the efficiency of the fan as a whole improves and the motor load is reduced, which leads to a considerably extended service life. In addition, it ensures that most standard motors can withstand 10% overvoltage and 20% undervoltage. This prevents failures in areas where power grid fluctuations are common.

The right data with practical applications in mind

Where suppliers of other motors often only show data from separate motors, we always show the performance of motors in combination with impellers. We acquire the required measurement data using our motor test bench and our advanced wind tunnel. Based on the performed tests, we deliver the optimal combination that matches the practical demand, and we show results that are realistic in practical applications.

Optimal service

As we develop and produce our motors ourselves, we are able to offer extensive service. This includes repairing motors, supplying alternative products or sending parts. In addition, we provide a 3-year warranty on our Multifan, Mf-Flex and EMI motors as standard.
