There is a very important accessory in the whole house furniture cutting machine equipment. This accessory is the frequency converter, which is driven by the spindle motor for processing, which can make the equipment run more smoothly, the speed is smoother and more stable, and the processing accuracy is guaranteed. Besides, what else does the device do?

1) The purpose of frequency conversion: constant voltage control or constant current control, etc.

2) The load type of the inverter: such as vane pump or positive displacement pump, special attention should be paid to the performance curve of the load, which determines the method of application.

3) Matching between inverter and load:

①. Voltage matching: The rated voltage of the inverter of the whole house furniture cutting machine is consistent with the rated voltage of the load.

②. Current matching: The rated current of centrifugal pumps and frequency converters commonly used in CNC cutting machines is consistent with the rated current of the motor. For special loads, such as deep water pumps, it is necessary to refer to the motor performance parameters to determine the current and overload capacity of the frequency converter.

③. Torque matching: This may happen when there is a constant torque load or reducer.

④. When the inverter of the whole house furniture cutting machine drives the high-speed motor, due to the low reactance of the high-speed motor, the higher harmonics increase, and the output current value becomes larger. Therefore, the capacity of the inverter for the cutting machine used for high-speed motors is slightly larger than that of ordinary motors.

⑤. If long cables are to be run, measures should be taken to control the influence of the long cables to the ground coupling capacitance, so as to avoid insufficient output of the frequency converter of the cutting machine. Therefore, in this case, the capacity of the inverter should be enlarged by one gear or an output reactor should be installed at the output end of the inverter of the cutting machine.

The purpose of the inverter installed in the whole house furniture cutting machine is to play the role of constant voltage control or constant current control. This equipment can achieve better processing results and really play an intelligent and automatic role.
