How to realize positive and negative rotation of electric drill motor
An electric drill is a drilling machine that uses electricity as power. Is the power tools in the conventional products, but also the largest demand for power tools products. 35% of China's power tools are produced and sold each year. The main specifications of electric drills are 4, 6, 8, 13, 16, 19, 23, 32, 38, 49mm, etc. the figures refer to the maximum diameter of the drill drilled on the steel whose tensile strength is 390N/mm2 (). For non-ferrous metals, plastics and other materials, the maximum drilling diameter is comparable to the original specifications of 30 to 50%.
By reversing the switch of the rotor or stator coil, the reversal is realized.
