High Efficiency Brushless AC Motor/Generator

This is a demonstration of a newly invented high efficiency brushless A/C motor/generator. Unlike existing A/C motors and generators, it has very low resistance. You can generate a 3 phase +/- 10 volt 30 Hz A/C voltage just by free spinning the rotor by hand. This technology is developed by ACT (Advanced Control Tech) and is patented pending.

Yes, we are in US. The size available is about 3KW. We also build the high efficiency motor system. The OEM price will be compatible with any existing motor/generator with much better performance. We can build and deliver per your specification if you have quantity order.

In principle, it is similar to brushless servo motor. However, due to using non metal stator, the rotor is more smooth. The position of the rotor can be sensed in the wire winding through digital control, no encoder is required. The efficiency of the motor can be greatly enhanced through digital control. In fact, it is closed loop control, the currents is only injected when the power is needed. The design is already been awarded with US patent.

We can get 95% efficient for the most operation speed. The higher speed will have even higher efficiency. We are looking for specific application. Anyone if interested can direct contact me.

how is this different from an outrunner brushlees motor?

[splee888]

It is different. It has no steel for the stator winding which will cause clogging when you turn it as shown in the outrunner brushless motor. As you can see in the video we can turn it very smoothly.

Where is a video showing measured data to confirm your efficiency?? Looks pretty cool, but all I see is a regular 3-phase motor turned inside out. For sure, this has applications for energy storage, because the rotating moment of inertia is further from the center of the assembly, thus maximizing energy storage in a given package size (assuming same RPM and size of a regular motor). However, this is hardly new. Baldor and Synchrony easily get 97-98% efficiency. Documented and displayed...

Patent your cock you stupid cock wanking yankee. Everything is patents with you lot to the point nothing good comes out of US any more accept franchise brands and weapons of mass destruction. Things that make you go boom...

CSIRO Australia invented the Ironless core axial flux motor/generators years ago. Way better than this.

open source bro.

[KirkMcLoren]

are you in the US?

Are you in production?

what sizes are available?

what is OEM pricing?

[MrWishiwas18again]

@splee888 did you ever get this to operate on a wind turbine? I have been working on an idea and I have a way of turning this motor with a consistant rpm. what higher speeds do you consider to be optimal for your motor? If you hooked it up to you home power supply would you need an inverter? Thanks for posting. (By the way, I have a very specific application for this motor so maybe we should talk.)

Hey, keep at it and good luck. Germany is hoping to be nuclear free someday. Maybe they are working on something like this.

[JeremyB796]

could you put power to it and have it generate power during then?

[splee888]

@leaualorin The patent was already award. The efficiency can be 95% in a full load condition. The wire is using normal copper wire.
