The invention relates to a power starting circuit, a power supply circuit, a controller, a motor and a vehicle. The power supply starting circuit comprises a power supply, a first resistor, a first voltage-regulator tube, a first anti-reverse diode and a first capacitor. The power supply, the first resistor, the first anti-reverse diode and the first capacitor are sequentially connected in series; the first voltage-regulator tube is connected in parallel with the first anti-reverse diode and the first capacitor; one end, connected with the first anti-reverse diode, of the first capacitor is connected with a power supply pin of a control chip; and the output voltage of the power supply is greater than the power supply voltage of the control chip. According to the technical scheme provided by the invention, the conventional RC charging circuit is used for supplying power to the control chip, so that the circuit design is simplified, and meanwhile, the reliability of the circuit is improved. The cost of the high-voltage emergency power supply can be reduced, and the working reliability of the high-voltage emergency power supply can be improved.
