BO motor stands for Brushless Outrunner motor. It is a type of electric motor commonly used in model aircraft, drones, and other remote-controlled vehicles.

BO Wheel stands for “Brushless Outrunner Wheel.” BO Wheels are essentially electric motors in a wheel form factor, with the motor built into the wheel hub.

One of the key advantages of a BO motor is its efficiency. Unlike brushed motors, which use brushes to transmit electrical current to the rotor, BO motors have a stationary coil, eliminating the friction and wear associated with brushes. This allows BO motors to run cooler and last longer than brushed motors.
