The invention relates to the motor technology field, more particularly to an integrated driving motor without a position sensor. The driving motor is provided with a motor; and the motor is composed of a stator, an external rotor, a rotor spindle, and an end cover. The driving motor is characterized in that: a driver is arranged in the motor and is fixedly connected with the end cover; the end cover and the stator of the motor are mutually connected to form an integral body so as to strengthen heat radiation capability of a module; the driver is composed of a power plate and a control plate; the power plate is provided with a major loop, an inlet wire open-phase detection circuit, a bus current detection circuit, an under-voltage and over-voltage detection circuit, a counter-electromotive force detection circuit and a switch power supply circuit; and the control plate is provided with a DSP control system circuit and a communication module circuit. According to the invention, on the basis of the above-mentioned structure, the driving motor has advantages of compact structure, high-density power, high efficiency, low noise, high integrated level, and low cost and the like.
