The invention discloses a driving control circuit of a motor and the motor with the driving control circuit. The driving control circuit comprises a power supply, an inverter, an external unit and a control unit, wherein the power supply is used for supplying power to the driving control circuit; the inverter is connected with the motor and the power supply respectively; the external unit is used for sending out an external request command; the control unit comprises a wind speed curve synthesizer, a control logic circuit and a driving circuit; the wind speed curve synthesizer is used for outputting a speed command of a wind speed control curve according to time sequence and the external request command; and the control logic circuit is used for generating a corresponding rotational speed control signal according to the speed command, and controlling the driving circuit according to the rotational speed control signal so that the driving circuit outputs a driving signal to drive the inverter, and the control on the rotational speed of the motor is achieved. The driving control circuit is simple in circuit structure, and the cost is also relatively low; and meanwhile, control complexity is effectively reduced, and the reliability of the circuit is improved.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a motor drive control circuit and a motor with the drive control circuit. Background technique [0002] During the use of the motor, it is sometimes necessary to combine multiple speeds to meet different application requirements. For example, in wind applications such as air conditioners, fans, and air purifiers, the combination of various speeds can form natural wind, sleep Wind, etc. At this time, it is necessary to control the operation of the motor according to the preset speed curve according to the selected external demand type. [0003] In related technologies, the speed controller of the fan obtains the speed signal of the motor according to the type of external demand, and sends a speed control signal to the control unit of the motor driver according to the speed signal, and the control unit controls the motor to run at a set speed to meet various applications. need.
