The torque is exactly proportional to the exciting current allowing high precision, flexible torque control. FIG. 13 illustrates the configuration of pole member 400′ which must be added to the configuration of FIG. 3 when multiple brake discs are employed. Pole member 400′ is provided with a hole 404′ defined by the interior cylindrical surface 405′ which is of a diameter slightly larger than the outer diameter of hub member 500′ as defined by the end surfaces 524′ of the air vanes 512′. The pole member 400′ is thus capable of receiving the hub member 500′ within the hole 404′. Located radially around the hole 404′ is a plurality of teeth 406′ separated by a plurality of recesses 408′. The recess 408′ serves as a channel which directs the flow of air radially outward. It should be noted, as more clearly shown in FIG. 15, that the teeth 406′ on the first side 412′ of pole member 400′ are located opposite the recesses 408′ located on the second side 414′ of pole member 400′. This allows the same pole member 800 to be used whether there is a single brake disc or multiple brake discs. The pole member 400′ is bounded by the outer cylindrical surface 410′, the inner cylindrical surface 405′, the first side numbered 412′ and the second side 414′.

VW Beetle 1966: Air cooled engine based on WW2 technology. Maximum Output: 50hp, Top speed: 123 km/h. Create your own music format: AMPS (Automatic Programmable Music Selector) lets you randomly select 15 of your choices from the disc’s 20 selections and program them in any order you like. Locate the music you want quickly and easily with APLD (Auto Program Locate Device) while APSS (Auto Program Search System) skips forward to locate the beginning of the current selection. You can enjoy immediate repeat play of an individual song or the entire disc with convenient repeat function. Conical rotor brake motor incorporates the brake as an integral part of the conical sliding rotor. When the motor is at rest, a spring acts on the sliding rotor and forces the brake ring against the brake cap in the motor, holding the rotor stationary. When the motor is energized, its magnetic field generates both an axial and a radial component. The axial component overcomes the spring force, releasing the brake; while the radial component causes the rotor to turn. There is no additional brake control required.

Did you know that Bristol has a hidden river running right through the city centre? Nope, neither did I! The Frome River used to flow where the Hippodrome is now, but it became so polluted that we buried it! Join our environmental historians for a hands-on journey around Bristol’s rivers and discover why Bristol’s hidden river history is so important in shaping our lives. The printed circuit board is not available ready made. In figure 1, Si is the brake pedal switch, and Lai and La2 are the brake lights. Perhaps the best way to describe what these three gadgets do is by reciting this writer’s personal experiences during the interview demonstration. That way I will not merely be telling what the inventor says they do, but I will reveal what happened when I tried the experiments myself. When we start talking about how and why the things work as they do, we’ll have to rely on the inventor’s explanations. Why bother with that? Don’t you just go out there and ride it hard, and do what you can do? Well not quite. You see for aerobic endurance events like time trialling, good pacing is critical to attaining the best result (in this case the maximal distance in an hour).

In FIGS. 5 through 7 only a single armature magnet 24 is disclosed, while in FIG. 8 a pair of armature magnets are shown. For purposes of understanding the concepts of the invention the description herein will be limited to the use of single armature magnet as shown in FIGS. 5 through 7. Clutches and brakes that have not been used in a while can rust on the contact surfaces. This is generally not a major concern because the rust wears away within a few cycles, leaving no lasting impact on torque. In an attempt to simplify the desired illustration, FIG. 10 has been included. FIG. 10 is basically the same as FIG. 9 except that the cover member 50, the first hub member 500 and the second hub member 700 have been removed. The remaining members which are clearly illustrated in FIG. 10 show the offset relationship between the teeth 406 of the first pole member 400 and the teeth 812 of the second pole member 800. Each of the teeth 406 are located opposite recesses 814. The location of the brake member 600 is also shown in FIG. 10. This offset relationship is well known to the art of eddy current type hysteresis clutch – http://www.validmagnetics.com/component/jshopping/hysteresis-clutches.html and brake devices and the inclusion of FIG. 10 is merely meant to serve the purpose of a clear illustration of portions of the above desription. With the above description of the device of the present invention in mind, the following
