Electric Generators


Nothing beats an Ideal generator. Fabricated in our state-of-the-art Ohio Works, Ideal generators are built to last. After all, Ideal is well-known for its reliable, efficient, and robust generators used in diesel engines, gas, steam, geothermal and hydroelectric installations. Our expert engineers and craftsmen have decades of experience developing custom generators for a variety of applications. At Ideal we have the resources to design, build, test, and install generators that provide you with the legendary quality that you’ve come to expect from us over the past 100 years.

Whatever your needs, our machines are Ideal.

Mechanical Features

Rotor Construction

Ideal generators are built using integral pole laminations, bolted and riveted together under high pressure before shrunk-fit and keyed to the shaft, eliminating the need to separately attach field poles or pole tips. Generator field coils are tension wound using insulated rectangular copper wire and aluminum supports are spaced to secure the field coils under any operating condition. Larger four-pole generators are constructed using a solid forged salient pole rotor. This technique yields a stiffer and more mechanically stable rotor than the laminated style, allowing for the construction of generators with incredibly high output ratings. Our rotor assembly process is controlled for high-quality through our Ideal standards, more stringent than those found elsewhere in the United States or internationally. 


Ideal’s four-pole generators incorporate oil-lubricated split-sleeve journal bearings. All bearings are designed for flood/pressure lubrication or self-lubrication, and most are furnished with oil rings to provide bearing lubrication during an emergency shutdown.

Electrical Features

Sealed Insulation System

Ideal Electric’s standard insulation system includes Class F vacuum-pressure impregnation with polyester or epoxy resins. Both systems pass immersion and spray tests per NEMA 1-20.49. Corona protection is provided as standard for stators above 6000 Volts.


Brushless excitation combines low-cost with performance suitable for nearly all applications and eliminates the problems of brush wear, meaning less maintenance time. Ideal Electric’s brushless excitation combines a high-frequency three-phase output with full-wave rectification, which assures minimum ripple current and faster response. Ideal rectifiers are mounted on a copper heat sink, and redundant fused rectifiers can be furnished for critical applications. 

A permanent magnet pilot exciter is typically furnished as an integral part of the exciter for use as a power supply to the voltage regulator. Using a permanent magnet pilot exciter in place of a power transformer provides the advantages of black start capability and current forcing under short circuit conditions.

Brush-type excitation is available if required.

Voltage Regulators

Ideal Electric offers an innovative electronic voltage regulator system as part of our brushless excitation package. Features such as VAR/Power Factor control, excitation limiting, and motor operated controls are also available. 

Industry Standards

Ideal Electric manufactures generators to meet all current industry standards including IEEE, ANSI, NEMA, API, and IEC. Special certification is available through CSA, ABS, DNV, Lloyds, and others upon specification.

Ideal Electric routinely designs motors for hazardous operation in Division 2 / Zone 2 environments with CENELEC / ATEX certification available.

Generator Applications


Ideal Electric leads the United States in small hydroelectric experience, with over 200 projects and 800 MW installed. Ideal has the capability to produce powerful, rugged hydrogenerators for any environment. Our advanced Ohio Works testing floor allows us to develop fully optimized, highly efficient hydrogenerators for any power production scenario. We have the expertise necessary to develop hydrogenerators that meet your needs and exceed your expectations. That’s the reason Ideal hydrogenerators can be found worldwide, including at the Hoover Dam.



Ideal electric has the means to develop robust, highly efficient wind turbine generators. Following the significantly rapid evolution of the global wind market, Ideal continuously innovates and improves the generators that allow for clean, renewable energy. Be it induction, synchronous, or DC, Ideal can build the right generator for you. 


Harnessing power from deep below the surface, Ideal generators make it easy to produce clean energy. Regardless of the geothermal power plant configuration, Ideal creates incredibly efficient, cost-effective, highly flexible solutions to keep you generating power.


Ideal Electric has expert knowledge when crafting turbogenerators for use with gas or steam turbines. Our years of research and development have yielded innovative turbogenerators of all speeds, sizes, and applications. 

Variable Speed

Ideal’s variable speed generators optimize efficiency by allowing for variable speeds, meaning your machine can be tuned to fit the power source’s speed. These efficient machines yield incredible performance at every speed possible.

OUR History

May 28, 1903; The Ideal Electric & Manufacturing Company is created out of the Card Electric Company in a 2,500 square foot converted horse carriage shop. The company built split frame motors for streetcars and elevators. A century of continuous innovation and corporate growth followed and in 2020 IDEAL celebrated 117 years under new, privately held, American ownership.
