IDEAL ELECTRIC is an American manufacturer of specialty, high-power electric motors, generators, condensers, power systems and controls since 1903

Ideal Electric Product


IDEAL has been a leading supplier of low, medium and high-speed synchronous and induction generators for over 115 years. With thousands of these generators in operation around the world, our machines have proven their reliability in virtually all types of applications and environments, including gas, steam, and geothermal.

Our experience and conservative design philosophy, combined with top quality materials and workmanship, result in a rugged, reliable, high-quality generator that is among the best available in the world today.

Hydro Electric Generators

IDEAL ELECTRIC is the US leader in small hydroelectric experience, with over 250 projects and 800 MW installed. Exclusive US single source company – capable of producing both generators and switchgear and allowing for sole sourcing of a coordinated electrical package.


Synchronous condensers are fundamentally a synchronous motor that is not connected to any driven load. Once started and connected to the electrical system it operates at full leading power factor to put VAR’s into the network to support the system voltage or maintain the system power factor at the desired level.

Induction Motors

Ideal Electric Co. has been a leading supplier of Low, Medium, and High voltage Induction motors for Power Generation, Oil & Gas, Petro-Chemical, Mining, Steel Plant, Sugar Mill, Municipal Water Applications, and Boiler Plants in Hazardous (Explosion Proof) or Non-hazardous areas. Our state-of-the-art manufacturing facilities guarantee that all motors meet various customers’ requirements with regard to delivery and quality.

Synchronous Motors

IDEAL ELECTRIC has built synchronous motors for over ninety-five years. Our expertise, combined with high-quality materials and manufacturing processes results in a reliable, cost-effective motor with high performance and low operating costs.

Permanent Magnet Motor/Generators

Permanent Magnet electric motors and generators offer unparalleled power density, efficiency across a variable speed range, and more torque-per-pound than other conventional technologies. These capabilities allow for machines in applications never before thought possible, as well as direct-drive systems in compact envelopes.

IDEAL has deployed numerous multi-megawatt permanent magnet synchronous generators, the first of which was introduced in 2018. The air-cooled machine sets new benchmarks for power density and weight saving in mobile gas turbine power unit applications for electric hydraulic fracturing or IDEAL ELECTRIC eFrac.

Switchgears & Controls

IDEAL ELECTRIC designs and manufactures a full-range of custom-engineered switchgear and control solutions. We are unique in that we are the only US manufacturer that is capable of producing both rotating equipment and the switchgear to control it.

Up to 40,000 kW

IDEAL's Mansfield, Ohio facility has the capability to build machines to the 40-megawatt (50,000 HP) power range depending on the rotational speed. The largest machine to ship from the factory to date is 265,000 lbs.

Voltages to 15kv

IDEAL pioneered high voltage insulation systems and that legacy is continued today, backed by thousands of low and medium voltage machines, many in corrosive environments.

IDEAL's Mansfield, Ohio facility has a very unique 14' (4.27m) VPI system - one of the largest throughout the Americas.

2 to over 160 Poles

IDEAL builds super-slow to high-speed machines with 2 to more than 160 Poles.

High Speed

While IDEAL is most known for our multi-pole, slow speed machines and benchmark setting 4-pole machines, our latest Permanent Magnet and Ultra-Performance Induction technology has found application in high-speed machines from 4,000-28,000 RPM. 

Fixed & Variable Speed

Our motors and generators are designed for both fixed and variable-speed applications. In fixed speed, we support all starting methods, and in variable-speed, motors are designed for all variable-speed drive types and technologies.

Variable-speed generators are designed for matched systems to specific applications in renewables; wind and hydro-power, hybrid marine and land power, defense and other speciality applications.

Hermetic Motors

In the 1940's IDEAL became a pioneering maker of hermetic motors. In the 1960's the 2,000 HP barrier was broken for refrigeration compressors. Carrier Corporation acquired IDEAL in the 1970's and subsequently became part of United Technologies Corporation (UTX). UTX divested the company in the 1980's, yet IDEAL remained a leading supplier of high-horsepower, medium and high-voltage hermetic motors with marquee installations across the world and on the oceans, including air conditioning the Queen Mary II.

All Cooling Methods

IDEAL offers all typical air and liquid cooling methods as well as specialty, exotic and otherwise challenging cooling solutions. 

Severe Duty

While all IDEAL machines are built to outperform, some applications and environments require special considerations for severe duty. The more demanding the application, the more IDEAL we become backed by thousands of references.

Nema & IEC Standard

IDEAL builds to NEMA or IEC standards.

Hazardous Environments

IDEAL machines are operating in every hazardous environment.

ATEX, Ex, ExN, Class 1 Division 2, H2S

Brushed & Brushless Excitation

A hallmark of The Ideal Electric and Manufacturing Company was pioneering the move to brushless excitation technology in the 1950's. Today we uniquely offer both brushed and brushless solutions.

Synchronizing Systems

IDEAL offers both its thoroughly modern Digital Synchronizing System (DSS) in addition to legacy synchronizing solutions.
