Electric motor drive system. The power of Kolmer

There’s definitely no shortage of electric motor drive systems. There is a great variety available in the market, from small to large, because everything that has to rotate can be driven by an electric motor. Whether it is the drive system for a concrete mixer at a construction site with an electric motor of 1.5kW or a cool water inlet pump of a chemical plant of 1.5MW, there is an electric motor available for every application.

The right electric drive system

Not every standard electric motor can do its job well in varying circumstances. Environmental factors play an important role in the selection of the right electric drive system. If a high ambient temperature is to be expected, the first thing to look at is the heat output of the motor.

Are there high humidity conditions? If so, we will have to zoom in on this. With the knowledge and expertise of our sales team, all options for electric drive systems are discussed and detailed. Together we will always arrive at a good solution and the best electric motor drive system.

Critical temperature

When selecting the electric motor, we also look at the required capacity. If the motor capacity is ‘just about’ enough, the motor temperature may become critical. If the temperature is too high, the motor may break down. The ‘operating temperature’ of the motor could easily exceed 70°C.

If the internal ‘hot spot’ temperature, the warmest and most critical point of an electric motor in the winding, exceeds 155°C, the electric motor drive system will break down due to a short circuit in the motor. This temperature happens to be the melting temperature of the insulation materials used, which fall into insulation class F.

What falls under 'drive'?

The term ‘drive’ is very broad. It includes everything that needs to be set in motion. You could, of course, do this with an electric motor, but only if there is electricity available. Electricity can however also be supplied by a diesel generator, which includes a generator set. Other types of drive systems include internal combustion engines, or the use of hydropower or wind power. The mills that can be admired at the Zaanse Schans are a good example of drive technology by means of a windmill.

These mills have made a major contribution to the Golden Age of our country. With the help of the mills we could saw the planks for our ships faster and better. This drive technology was again used at a later stage in our polders, to reclaim land. All this would not have been possible without the power of the wind.

Environmentally conscious electric drive technology

The industrialisation of the past decades has changed a lot in the field of (electric motor) drive systems. In recent years, the energy consumption of the electric motor drive system has been under close scrutiny. Every kWh of energy we use produces around 350g of CO2 emission.

There is much to be gained if we can select the electric motor in such a way that it only provides power when it is really needed. At Kolmer Electric Motors we are therefore constantly working on the improvement of electric motors for electric drive technology.

Kolmer Top Coating

An engine that does not flake and does not rust, that is our goal when we start an extensive research project in 2016. We develop a coating that does hold and the test results exceed all expectations. Engines keep looking great year after year, no matter the conditions. TNO is testing the safety and we are now fully in production. Kolmer Top Coating anchors itself through the paint layer in the underlying aluminum and cast iron. A water-thin, super strong layer that protects for years and can be used on all our Cantoni and a selection of EMF and Cemp engines.
