Stepper motor stepper motor using subdivided driving technology can greatly improve the stepping motor running quality, reduce the torque ripple, restrain oscillation, reduce noise and improve resolution step moment. If using reactive stepper motor, the performance improved obviously at the same time also can reduce the cost of the products. Power consumption in the whole society, there are about 70% cost in the field of industry, and industrial electrical power consumption and occupy 70% of all industrial electricity. In retrofit of industrial motor, therefore, can greatly reduce the energy consumption of the whole society. It can be seen that the motor energy saving potential is tremendous, improving the efficiency of the motor will be the primary method of industrial energy saving. Improving the efficiency of the stepper motor can be mainly through two ways, one is by frequency converter speed control, improve the operation efficiency of ac motor; The second is using efficient motor. Depend on the frequency converter is the main way in the field of industrial energy saving, energy saving of frequency converter efficiency generally over 30%, in some industries and even reached 40%50%. The proportion is still low efficient motor market application, but with minimum energy efficiency standards and subsidy policy support, the future market application of efficient motor proportion will rise sharply. Stepper motor is mainly used in some places that have requirements of positioning requirement. For example, thread cutting workbench drag, flocking machine workbench (Pore), packing machine,Fixed length)。 Basically involves positioning occasions are applied. Widely used in the ATM machine, spraying machine, sparks machine, carving machine, pictorial machine, spraying equipment, medical instrument and equipment, computer peripherals and mass storage equipment, precision instruments, industrial control system, office automation, robots and other fields. Especially suitable for smooth operation, low noise, fast response, long service life, high output torque.
