The invention discloses a motor speed regulation system. The motor speed regulation system is suitable for a winch of a boom hoist. The motor speed regulation system comprises a power supply, a frequency converter and a motor which are connected in sequence. The frequency converter converts the industry frequency alternating current power supply into a direct current power supply and then converts the direct current power supply into an alternating current power supply with the controllable frequency and voltage through an inverter to provide the alternating current power for the motor, so that the rotating speed of the motor is changed by changing frequency. The frequency converter comprises a rectifying circuit, a power factor correction circuit, a filter circuit, an inverter circuit, a microprocessor circuit and a man-machine interface circuit. The rectifying circuit is used for converting alternating current power into direct current power; the power factor correction circuit is used for improving power factors; the filter circuit is used for finishing filtering smoothing and energy storage of the direct current power; the inverter circuit is used for converting the direct current power to three-phase alternating current power; and the microprocessor circuit is used for controlling the power factor correction circuit and the inverter circuit to work according to orders sent from the man-machine interface circuit. By means of the motor speed regulation system, the product properties of the boom hoist can be improved.
