Tile Installation
Last year, for torque measurement, the motor was attached to a speed reducer. One end of the piece of thread was affixed to the axle of the speed reducer, while the other end contained a hook, which was holding a box. As the motor spun, the thread was slowly winding onto an axle. This lifted the box. The speed reducer ratio was approximately 1:150, which means that the motor needed to make 150 revolutions to make the axle rotate one turn. The box that was lifted contained a specific number of weights, which were actually ceramic tiles. Three ceramic tiles weighed exactly 1 lb. To achieve 0.5 lb. increments, one tile was split in half. The picture below shows also a regulated power supply (in the upper right corner) and the electronic counter (on the right side).
