[Suzhou Yu Qing Yu Qing grinder proxy factory price] standard mechanical grinder, grinding, grinding wheel motor start circuit according to tradition used to run. After the motor starts according to the rated speed operation, there are some fluctuations due to the grid voltage, load wheel changing workpiece friction will affect the motor speed error, standard wheel motor starter circuit is generally only a processing speed, it is difficult to adapt to different requirements of different size of the workpiece relative line processing speed, so that the workpiece machining precision is difficult to ensure. Therefore, improving the processing quality and processing efficiency, energy conservation and other considerations, the frequency conversion technology used grinder, you can receive satisfactory results.
