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.

Excitation

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.

INDUCTION

IDEAL designs and manufactures both squirrel cage and wound rotor induction motors. Our squirrel cage motors are built with sturdy copper bar rotors which, when combined with our conservative designs, rugged construction techniques, and engineering expertise, provide years of reliable service with extremely low maintenance requirements. These motors are available with various torque characteristics, and our low-slip, high-efficiency designs keep operating costs at a minimum.

Wound rotor motors are used in many applications where variable speed operation is required. The rotor windings are brought out through slip rings, and the motor speed is varied by adding resistance to the rotor winding.

SYNCHRONOUS 

IDEAL has built synchronous motors for over seventy 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.

Synchronous motors are well suited for a variety of applications, especially when high-efficiency and power factor are a concern. On average, synchronous motors are 1% to 2% more efficient than induction motors, resulting in a substantial reduction in operating costs over the life of the motor. Our synchronous motors can be designed to operate at unity power factor or leading power factor when overall system power factor correction is desired.

Low starting inrush is another advantage of synchronous motors and starting torques adequate for most applications can be obtained by using special alloy squirrel cage windings. The elimination of brush maintenance makes brushless excitation the choice of most customers.

Brushless synchronous motors also have the adv of being able to operate in Class I, Division II hazardous environments. Our brushless excitation system includes all of the excitation control and field application equipment needed for sync and similar equipment can also be supplied with a static excitation system. Static excitation is also available and is generally more practical on low-speed motors where brush wear is not a problem.

A variety of enclosures are available for every type of installation or classification, including those that meet NEMA/IEC standards.

Permanent Magnet

Permanent magnet synchronous motors have a variety of applications due to their high-efficiency and internal controls. IDEAL is capable of constructing precise high and low-speed units that run cooler than induction motors, which translates to less maintenance for you. Our robust permanent magnet motors can lead to substantial long-term cost savings.

WOUND ROTOR

Wound rotor induction motors substantially increase a system’s ability to efficiently start high inertia loads while maintaining low inrush currents.

2-Speed

2-speed motors are suited for use in systems necessitating multiple speeds. Our 2-speed motors can be constructed as single or double-winding machines with any enclosure. IDEAL can work with you to develop a machine that exactly fits your needs.

SWITCHED RELUCTANCE

IDEAL switched reluctance motors are built to achieve maximum efficiency at incredibly high speeds. These rugged machines are flexible and highly reliable, regardless of operating speed, temperature, and supply voltage. Ideal switch reluctance motors are a fantastic cost-effective choice for anyone needing a motor that can do it all.

POLE AMPLITUDE MODULATED (PAM)

The PAM induction motor is a highly flexible single-winding, two-speed machine with a variety of applications. Unlike standard two-speed motors, pole amplitude modulation system speeds don’t have to be a 2:1 ratio configuration – which allows for a much wider range of use.

DC

In addition to AC synchronous and induction motors, Ideal also has the capability to produce DC systems, too. Our powerful DC motors include custom-made, separately-excited, and self-excited machines that cover a variety of applications.
