Anhaltische Elektromotorenwerk Dessau

What Anhaltische Elektromotorenwerk Dessau does

Anhaltische Elektromotorenwerk Dessau GmbH (AEM Dessau) is a German manufacturer of custom-engineered three-phase motors, generators, and rotary frequency converters, founded in 1993 and headquartered in Dessau-Roßlau, Germany. The company was established by four founders who acquired part of the former VEB Elektromotorenwerk Dessau, drawing on a continuous heritage of electrical machine production dating back to 1948. AEM operates from a single 11,000 m² production facility with high vertical integration, manufacturing asynchronous and synchronous machines ranging from 160 kW to 5,000 kW (motors) and 160 kVA to 5,000 kVA (generators), with 3,000+ execution variants available. Core product lines include three-phase motors, three-phase generators, rotary frequency converter units for 50/60 Hz conversion, and reproductions of discontinued machines from historical OEMs including ABB, AEG, SIEMENS, and others. The company also produces specialty submersible motors (IP68) developed in collaboration with Bakker Sliedrecht.

AEM serves three primary verticals: hydropower/renewable energy (small hydropower generators with Pelton, Kaplan, Francis, and cross-flow turbines), shipbuilding and offshore (shaft generators, auxiliary diesel generators, and diesel-electric propulsion motors for cruise ships, container ships, mega-yachts, and dredging vessels), and industrial plants/heavy industry (motors for excavators, conveyors, cranes, mills, presses, and mining applications). The business model is direct B2B with custom quotation-based pricing; no public pricing is available, and each machine is individually engineered to customer specifications including power rating, voltage, protection class, cooling system, and certification requirements. The company sells globally, with documented reference projects across Germany, Austria, Italy, Switzerland, Netherlands, China, Japan, Denmark, Norway, and Rwanda, supported by a 14-language website, SMM trade fair participation, and a dedicated customer service department with a separate deflex GmbH spare parts division.

AEM is family-owned by the Storch family following a 2011 ownership transition. The company's revenue is not publicly disclosed. It is ISO 9001 certified since 1995, holds approvals for major maritime classification societies (ABS, BV, CCS, DNV GL, LRS, MRS, RINa), and maintains R&D collaborations with Otto von Guericke University Magdeburg, TU Chemnitz, TU Dresden, the Fraunhofer Institute, and WTZ.

Direct peers

• VEM Sachsenwerk: VEM is a German manufacturer of special motors, drive systems and generators, formerly the parent of AEM under VEM Antriebstechnik AG. It is the most direct historical and product-level competitor, both companies serving industrial and energy customers from eastern Germany.
• Indar (Ingeteam): Spanish manufacturer of custom generators and motors for hydropower, marine, and industrial applications. AEM explicitly reproduces Indar machines, and the two companies directly compete in small hydropower generator markets across Europe and Africa.
• Marelli Motori: Italian manufacturer of custom and standard generators and electric motors for industrial, marine, power generation and renewable applications. Closely comparable to AEM in power range, customization philosophy, and customer verticals (especially shipbuilding and hydropower).
• Schorch Electric (Weißenhorn): German manufacturer of large electric motors and special-purpose machines for industrial and marine applications. Historically a peer in the German mid-power motor market and one of the brands AEM explicitly reproduces aftermarket.

Broad incumbents

• ABB Motors and Generators: ABB is a global incumbent in industrial electric motors and generators with a much broader standard-product portfolio. AEM literally reproduces discontinued ABB machines, indicating both overlap and AEM's niche positioning around legacy and bespoke machines.
• Leroy-Somer (Nidec): Now part of Nidec, Leroy-Somer is a global manufacturer of industrial motors, generators, and drives. One of the brands AEM explicitly reproduces on the aftermarket side, and a direct competitor in the medium-power three-phase motor and generator market.
• Siemens Large Drives Applications: Siemens is one of the largest global manufacturers of large electric motors, generators and drive systems. AEM competes with Siemens for high-power industrial and marine projects, and lists Siemens as one of the OEMs whose legacy machines it reproduces.
• AvK / STAMFORD (Cummins Generator Technologies): Cummins-owned manufacturer of large alternators and generators for marine, offshore, and industrial applications. AEM competes in the same marine shaft generator space and lists AvK/STAMFORD among the brands whose machines it reproduces.
• WEG Industries: Brazilian-listed global manufacturer of industrial electric motors, generators, and transformers with a strong European presence. Competes with AEM in the industrial and renewable energy generator segments, particularly in the mid-power range.

Emerging players

• Hyundai Electric (Hyosung): South Korean manufacturer of high-voltage motors, generators, and switchgear with growing global share in shipbuilding and industrial markets. Competes with AEM in marine and large industrial motor projects, particularly for customers in Asia.
