Measurements as it relates to understanding a motor

current-induces torque in the motor. the efficiency of this current to force inducing measurement varies. at most probably 70% efficient on a curve starting at 1 to 70 then back down to 1. Efficiency can be limited by over or under timing. friction, inertia, and mechanical efficiencies add to or remove current.

voltage-the higher the voltage the higher the rpm can go. the opposite is true as well.

timing-the rotor has a magnetic center on each magnetic pole. the timing is the distance the centerpoint is from the sensor that senses it. there are 3 sensors and more than 1 pole.

Kv-RPMs per volt or a prediction of max rpm.

Db-sound pressure of the motor
