What is a chair chair? Dining chairs machinery, including dining chairs, plate furniture, office furniture, solid wood furniture and other wood products need to use the processing machinery, manual, semi-automatic, fully automatic points. Variety, involving a wide range. From the sawing, forming, profiling, drilling, open the tongue and groove, splicing combination, glue, paint to the packaging and other aspects, can be completed by the machine. When the machine is started with the woodworking machinery, the current of the motor is 5-6 times higher than the rated value, not only will affect the service life of the motor but also consume more power, and the chair machine is the same as the woodworking machine. The design of the motor selection will leave a certain margin, the motor speed is fixed, but in the actual use of the process, sometimes to lower or higher speed operation, so the frequency conversion is very necessary Of

Inverter can achieve the motor soft start, by changing the device input voltage frequency to achieve the purpose of energy saving, but also to provide equipment over-current, overvoltage, overload and other protection.
