high voltage- Synchronous Motors

Medium and high-voltage Motors - VEM

VEM concentrates on the complex demands of selected market segments of all industries with large-scale and special machines. Motors and generators such as traction or special designs take advantage of electromagnetic streamlining at low installation volumes. VEM builds asynchronous and synchronous machines from the low-voltage range up to 13.8 kV at an output of as much as 42 MW for customised applications.

 

 

 

 

 

Synchronous motors - VEM

Steel and rolling mill industry
Product range

Right from the beginning we have high performance slow-running motors for the metal industry in our delivery program. After direct current motors having dominated for a long time, today dynamic, high-quality three-phase motors are used: for larger torques as synchronous machines as solid pole versions, for smaller torques as asynchronous squirrel-cage motors. The mechanical construction is designed for high loads in rolling mill operation; equally the electromagnetic dimensioning fulfils the requirements of overloads, adjusting range and control dynamics. The cooling is predominantly reliant on air-to-water heat exchangers.

We supply motors for hot and cold rolling mills for reversal stands in single and twin assembly, for edgers, finishing and tandem mills in single and duo or quarto assembly for reeling, shear and auxiliary drives.

Chemical, oil and gas industry
Product range

The chemical and petrochemical plants require the employment of explosion-proof motors - dependent on the hazard potential (zone 1 and zone 2). At present we provide the ignition protection classes Increased Safety “e” and “n” (non sparking) (zone 2) for our low and medium capacity motors; our motors with high to extremely high capacity, as well as all synchronous motors, have the ignition protection class Pressurized enclosure “p“.

Special requirements must be taken into consideration with regard to certain chemical procedures, such as equipment for ammonia synthesis as an example, to ensure the avoidance of copper and cupreous alloys on the external construction of the motors. VEM motors are adapted to suit the special requirements of chemical processes. We supply motors for compressors, extruders, fans, mixers and pumps.

 

 

 

 

Water technology
Product range

VEM supplies efficiency-optimized motors for driving high-performance pumps especially designed for large flow rates for water abstraction from artificial lakes, rivers and oceans, and for the transport of raw, pure and industrial water in industrial, water supply and sea water desalination plants and for large waste water treatment plants.

 

 

 

 

 

 

Shipbuilding
Product range

VEM has many years of experience in building ship motors and it also has the licences from all of the important ship classification companies. We build and supply motors and generators for a wide range of all ship models. They range from the large-scale machine with a weight ranging from 200 tonnes to the broad spectrum of accessory drives. Our scope of delivery includes shaft, diesel and on-board electrical system generators, propeller drives, bow thrusters and transverse rudder drives, pump drives and drives from on-board auxiliary equipment.

 

 

 

Cement and mining industry
Product range

Large infrastructure projects in the “boom regions“ are leading to a strongly growing demand for building materials such as cement, steel and non-ferrous metals which in turn results in a constant demand for an increase in efficiency for the development and processing procedures in view of finite resources. The mining industry is also developing rapidly at present, since the supply of iron and non-iron ores in sufficient quantities is a requirement for the production of various final products.

Large amounts of these resources are broken, milled, transported, sighted and burned; dust, heat and mechanical loading leads to high requirements on the motors which VEM supplies for crushers, mills, fans, furnaces or conveyor plants.

Asynchronous motors with slip-ring rotors are especially suitable for the heavy start-up conditions for mills and crushers under full load and for fans with very large mass-moments of inertia. Cooling takes place primarily with air-to-air heat exchangers and separate ventilation of the slip ring area.
