    What does the KV and T mean for Brushless DC motor?

    kV refers to R.P.M./Volt. It is  how motors are rated, and does not mean KiloVolts. If we have a 12V electronic speed controller (ESC), the speed will be 12 times that number. The higher the kV rating the faster the R.P.M of the motor. The lower the turns, the higher the R.P.M. of the motor.3.5T...
