Types: po-mo-s
The highly efficient permanent magnet synchronous submersible motors are intended for driving submersible pumps. They are fully recyclable and thus conserve resources. The high efficiencies and the associated reduction in energy consumption guarantee lower operating costs and contribute to the protection of the environment.

Iron ore mining in Australia
Our customer was looking for a pumping system that offered greater motor efficiency and performance with the same size and could withstand the harsh conditions of the Western Australian mining industry. The 6 highly efficient submersible pump systems are used in iron ore mining to keep the mines in Western Australia dry.
Use in the Colbitz waterworks
The operator of the waterworks in Colbitz, TWM Magdeburg, was able to reduce the energy consumption of a well by around 24,500 kWh annually by replacing an asynchronous motor with a synchronous motor, thus saving 3,900 euros.
