    Hello Everyone,

    An Irish company is launching a new motor technology called E-Orbo. The interesting thing about their technology is they claim it produces torque without back EMF. This seems impossible, because I do not think a motor can experience a torque without experiencing a back EMF.

    Back EMF is absolutely needed for torque to happen.

    However, they have posted an experiment showing the voltage/current of their system does not change when it is loaded. It also does not change when it speeds up.

    I do not understand this motor.

    Here is a video of the tests they performed.

    Theoretically, can a motor produce torque without back EMF?

    Check out the latest video Steorn has posted.

    Steorn's Orbo Electromagnetic Interaction COP is greater than 1. Part 1 of 5

    Steorn has posted two more videos.

    They claim they have proven their E-Orbo technology is OU.

    hey back emf means the voltage due to eddy current...correct me if i am wrong...and is it so then please explain the phenomena

    No....In a motor,due to rotation an emf is induced which is in opposite with the applied voltage.....This limits the current in motor since resistence of armature is very small......
