This is brushless geared hub motor with electro magentic brake! together with motor controller smc-04(http://www.shayenmotor.com/motor-controller.html/brushless-motor-controller-with-electro-magentic-brake) 

 1]The gear ratio is 19:1. What material are the gears? Are they straight cut or helical?
Gear material is 40 cr, the modulation - roll teeth - heat treatment. Transmission system divides two groups, the first set of helical gear and a second group of gear is a straight line.
2]What is the maximum noise level?
A sound meter test: the biggest noise<=58 db.
3]What is the 10 years life expectancy based on? Hours? How long have you had the motors in service?
1. Using the noncontact electronic commutation, the electrical unit without contact wear;
2. Working current little calorific value;
3. Using ndfeb permanent magnets, magnet can resistance to high temperature 120 ℃ not demagnetization,
4. The gear transmission system using 40 cr alloy structural steel, quenched and tempered after having good comprehensive mechanical properties, the gear hobbing machining carbonitriding heat treatment way, of the reentry after improving gear surface hardness, wear resistance and fatigue strength.
5. The omega 73 # grease gear surface, can effectively reduce the amount of gear wear, and noise reduction.6 type without maintenance.Minimum normal maintenance free time: according to the calculated using 3 hours a day on average, 10 years time 10000 hours. 
4]Water protection? IP?
Have waterproof performance, the protective class is IP54.
5]Is 36v 100rpm winding available?
We can design and production, but it must increase the biggest diameter of motor (electrical unit speed reduction ratio increases, the transmission system)
6]What is the holding torque of the brake?
Adopt Taiwan Thousand Adai electromagnetic clutch,friction torque 3 N - M, 3.5 N - M static friction torque.It is 24v 10.8w.
