INFORMATION - Rare Earth brushed DC permanent magnet motor. Speed at no load is 3150 rpm (yes, we know that the 'other guys' motors are 2500 to 2650 RPM and why we have more torque than they do at $20 to $40 less than they are charging). 746 watts per horsepower puts this 350 watt little guy at just just under a half horsepower (for a mathematical sidebar please visit the Wikipedia and enjoy the history of 'horsepower' and while you are at it do the conversion to 'Newtons' since everything is going metric and a horse is not metric http://en.wikipedia.org/wiki/Horsepower#Electrical_horsepower. Uses a 13 tooth HTD industrial belt pulley (notice how so many of these parts are 'industrial parts'?). This motor is a work horse and is very strong for its size. Here comes the fun stuff. The HUB motor is stronger than the NO HUB motor and costs a little more. The inherent design of the HUB puts the support bearing out further and only leaves about 1/8' inch unsupported before getting to the drive gear. The additional support helps if the belt is too tight and you go off road, jump curbs and really jar things around. This can cause the shaft to fracture and ruin the rest of the ride. We recommend that if you have gone through several NO HUB motors that you upgrade to the HUB motor or ease up on the rodeo riding. Of course we can sell you the upgraded HUB swing arm along with a HUB motor for you to install on your electric steed or if you send us an insurance certificate with at least a 2 and six zeroes and make us the beneficiaries of the policy we can tell you how to do the conversion yourself, if you have a large drill press that can select a speed of 195 RPM, have a bi-metal hole saw with a pilot bit, have a really nice clamping arrangement that will keep the whole thing from ripping off your arm at the joint. Your cause will be helped if you are or have been an Eagle Scout and know how to operate machinery and keep all of the fingers you started out with. Please notice the motors in the picture. One does not have a hub (E7070191), one does (E7070192). If all else fails, a no hub motor will work in a hub motor bracket but not the other way around. Notice the OK in red on the label. Every motor, battery, throttle, contoller etc. (read everything) is tested before installation and then track tested prior to shipping or delivery. How lucky can you get? NOW go ahead and order the correct motor. You cannot order here, you need to go to E7070191 (NO HUB) or E7070192 (HUB) |
