Abstract
The utility model relates to a motor with built-in driving and controlling circuit. An existing coil part of the motor stator is provided with a circuit board so as to help an existing coil to finish the integrated connection on the circuit board. The signal inlet end and the signal outlet end and a sensing control end of the existing coil are insulated by a signal guide pin arranged on the circuit board to penetrate the through hole of the back motor cap, therefore, the signal is transmitted to the circuit board. The both ends of the hollow rotor cylinder are sealed by the two end panels. The center of each end panel forms a concentric hole and the shaft core of the rotor can be clamped in the hole tightly. In addition, the support of the rotor is strengthened and the weight is reduced so that the turning inertia of the motor rotor is reduced.
