With salient poles – GSV
With permanent magnets – GSP

Synchronous generators are among the TEM division’s products in highest demand. They are suitable for all types of hydro turbines with outputs up to 30,000 kVA. In spite of the product’s common characteristics,it is a customized product manufactured according to requested parameters for each specific application. The machine design is worked out by a team of experienced designers. A thorough quality inspection is done during the manufacturing of each unit. The machines are fitted with bearings of the highest quality. The continuous care of the R&D team for electric rotating machines enables us to offer synchronous generators of high quality and a long service life.

Small Hydropower Plants – GSH, GSV, GSP

Generators for small hydropower plants are distinguished by robust construction and excellent parameters with high efficiency. They are attractive, above all, due to the combination of high reliability and innovation that they feature. This results in an economically advantageous solution. Thanks to a new design of rotors with salient poles,the machines achieve high outputs up to 30,000 kVA. Our long experience ingenerator manufacturing has resulted in the production of ecologically clean energy in more than five hundred hydropower plants.

Wind – GSV, GSP

Synchronous generators have been optimized for outputs up to 30,000 kVA, they feature high efficiency and precise speed regulation. A new innovation is our generator with permanent magnets with outputs up to 4,000 kVA. Thanks to the progressive design, the machine is 30 % lighter than machines with a wound rotor. With excellent efficiency, easy installation and longer service intervals, the machine maximizes yield. The generators are optimally compatible with the mains; feeding is ensured with frequency converters.

Marine – GSH, GSV, GSP

These generators are suitable for use in the shipping industry: for tankers, supply ships, multi-purpose cargo ships and ferryboats. They are used to feed electrical networks, emergency supplies of special aggregates or for auxiliary drives. The machines are intended for individual or parallel operation.

Pilot exciters – BP

Special synchronous generators with permanent magnets, which are used for power supply of automatic voltage regulators of synchronous machines and other devices with suitable parameters. The maximum power of the pilot exciters is 3500VA. Speed range 0-1500 rpm. More information can be found in the enclosed pilot exciters datasheet:

With a short-circuit armature
GAK series

GAK series of asynchronous generators with a short-circuit armature is suitable for all types of hydro turbines with outputs up to 1.5 MW. This series meets the specific requirements for alternators intended for this application. The main features are robust construction and sufficiently dimensioned machine parts. The rotor is executed with regard to a possible occurrence of increased rotational speed. The generators are destined both for parallel operation with the mains and for single operation.

Thanks to a wide range of variants and accessories we can fulfill broad demands of customers; horizontal or vertical design, antifriction or slide bearings, free shaft ends according to demand, buildup of terminal boxes, etc.

Small Hydro Power Plants – GAK

Due to its parameters this generator type is primarily suitable for hydropower plants with turbines of outputs up to 1,500 kW. Asynchronous machines do not need any regulator and, thanks to their simpler construction, they have a good return of investment even with lower outputs at a hydropower plant.
