Energy Saving Motoradopting advanced electronic control system can run smoothly with a range of 180V---240V at rotating speed from500 --3000RPM.And most components are imported from America and Japan. The new generation industrial sewing machine electron controlling motor is able to meet demands of different kinds of sewing machine with a combination of: energy-saving, low temperature-rising, big torque, reliability and high efficiency. Compared with clutch motor, the industrial sewing machine electron controlling motor eliminating the useless power for no-load running can save energy by sixty percent. If a clutch motor consumes 2 to 2.5 KWH one day and such motor will save 1--1.5 KWH per day. Then one million such motors will save electrical energy generated by a medium-size hydroelectric plant. So when you invest on such motors, you will not only benefit yourself, but also the whole human beings.
