The main objects are to simplify the method of construction and reduce the amount of labor necessary and also reduce the cost of material while producing a strong and durable construction with reduction of size and weight of the machine.” The ‘136 patent, “Dynamo-Electric Machine,” “relates to an improved method and form of construction of dynamo electric machines which is especially applicable to comparatively small sizes of motors, generators and the like. In other words, ME’s key technology derives from a patent issued in 1920. A fascinating aspect of all of Calley’s Motor Excellence (ME) patents is that they cite US 1,361,136 as the earliest citation. Four of the Green Tech patents are found in the patentECO Energy | Energy efficiency | Motors & alternators | Design hierarchy (Index | Category | Technology | Feature), and the fifth is categorized as Transportation | Electric vehicle | Motor | Stator. Inventor Calley has 14 patents assigned to Motor Excellence for which he is the first-named inventor five of these issued from the Green Tech Pilot Program. In claim 10 one learns that “The stator of claim 2, wherein the stator is coupled to a wheel of an electric bicycle.” Individual cogging torque waveforms in the electrical machine may be evenly distributed across one-sixth of a voltage phase or other suitable spacing, resulting in a reduced magnitude and/or increased sinusoidality of the overall cogging torque waveform for the electrical machine." "Electrical machines, for example transverse flux machines and/or commutated flux machines, may be configured to achieve reduced overall cogging torque via implementation of a sixth-phase offset.
Their invention is entitled “Transverse and/or commutated flux systems having phase offset”, and is described in the abstract: Calley and co-inventors, all in Flagstaff, AZ their patent is assigned to Motor Excellence, LLC. Surely there might be a less noisy solution to their desire not to have to pedal? One might ask why bother to ride a bike, but I won’t.Į-bikes (electric bikes) would solve my local students’ need for locomotion, and my, and my neighbors’, need to retain our hearing.Įnter the US Patent Office’s Green Tech Pilot Program, and patent US 8,222,786, issued in July 2012 to David G.
I perceive them from a long distance, hear the Doppler effect as they approach and recede, and cringe as they pass the house – the motors may be small, but they are SHOCKINGLY LOUD AND PENETRATING.

Several high school students zip by my house in the mornings and afternoons on bicycles with tiny 2-stroke gas engines.
