[0002] A single-phase variable frequency speed regulating bench drill is a bench drill equipment with single-phase power input and variable frequency speed regulating function. Variable frequency speed regulating refers to changing the motor speed by controlling the power supply frequency of the motor. This speed regulating method is usually implemented using a frequency converter or a frequency regulator. Through variable frequency speed regulating, the working speed of the bench drill can be adjusted as needed to adapt to the processing requirements or process parameters of different workpieces.
