Millennial Research Corporation's Magnetronic™ Generator Emerges

Efficiency, power, durability, and performance are all important aspects of electric motors and generators. By utilizing a novel coil and magnet setup that harvests energy from both side of the coil, Millennial Research Corp brings all of these characteristics to the table with their Magnetronic™ Technology.

Electric motors and generators keep our modern civilization moving. Without them, the lights would go off and the world would come to a stand still. Due to widespread use of motors and generators, any new design that offers an improvement in efficiency, power, durability, or performance is very important. Millennial Research Corporation has spent years developing a novel motor design that pushes electric motor and generator technology to a new level. They have recently revealed a 100kW electric generator that offers many advantages compared to conventional generators.

Nearly a year ago, they had a major setback when three of their key personnel were killed on July 10, Nikola Tesla's birthday. This included the president, the COO, and the CFO of their partner company, Highland, Inc. In our news last year, we linked to a story Jeane Manning wrote about that development, as well as about the capabilities of the technology. 
The Magnetronic™ Generator prototype can produce over 100kW of electricity in countless applications including wind power, hydrokinetic power, gas or diesel work site systems, backup power generation, and commercial power generation. Like all motors and generators utilizing Millennial's
It is important to note that although the unit is rated at 100kW, that is when the rotor is spinning at 360 RPM. However, due to the broad speed range the unit can operate in,

Magnetronic™ Motor/Generator Design

In multiple ways, a Magnetronic™ device dramatically differs from an electric motor or generator utilizing conventional technology. The differences start in how the device is designed. Inside of a

Due to the modular design of the technology, each stationary coil in a Magnetronic™
The coils in a Magnetronic™ device are not complex. They are simple bobbin wound coils. Such coils can be manufactured or rewound very easily.

Maintenance Tips | Flash Over on Wound Rotor Motor Slip Rings ...

Preventing flash over on a Wound Rotor Motor’s (WRM) slip rings requires periodic inspection and testing of the rotor’s insulation system. The point of the rotor’s lowest insulation resistance on a WRM’s rotor circuit will almost always be between the exposed metal surface of the slip ring and the rotor shaft. Looking at the typical installation of a WRM it is easy to understand how dirt, carbon dust, and other forms of contamination can build up in the area of the slip rings.

During start-up the high slip between the rotor and the synchronous magnetic field of the stator induces a large amount of energy in the rotor’s windings. Lowered insulation resistance due to contamination build up around the rotor leads could easily lead to flash over (arcing between the rings or to ground) and damage the connections between the lead and the rings, the slip rings and possibly even the shaft.

Regular testing of the rotor circuit separate from the resistor bank is recommended to maintain a high level of dependability. Ensure your ground test lead is connected to the shaft of the rotor, if possible, to get the most accurate measurement of the resistance between the windings and the shaft of the rotor. While you are at it ensure you closely inspect the slip rings and their insulation for any build up of contamination and clean if necessary.
