Motors for fan manufacturers

EMZ delivered a 90 kW motor to a renowned fan manufacturer in France.

The motor is operated on the frequency converter so that the air flow can be controlled.
To guarantee the faultless operation of the drive, it was equipped with an electrically-insulated bearing
in our own workshop.

Asynchronous low-voltage squirrel-cage rotor:

Brand: EMK | Output: 90 kW | Voltage: 400 V | Speed: 1.500 U/min. | Safety class: IP55 | Efficiency: IE2 | Weight: 670 kg

EMZ supplies three-phase asynchronous motors to a German manufacturer of suction dredgers

The motors with a power range of 250 to 400 kW are used as the main drive for suction pumps for gravel extraction.

Owing to their open use on floating pontoons, the motors are constantly exposed to all types of weather
conditions. Especially in winter with rain, snow and ice. The robust cast iron EMK motors meet the requirements for this application. 

Three-phase asynchronous motor:

Brand: EMZ - EMK | Output: 250 kW | Voltage: 400/690 V | Speed: 1.485 U/min. | Safety class: IP55
