Shanghai four macro focus stepper motor field for 30 years, with the world many famous motor company maintained a long-term technical strategic cooperative relations, has for decades by the continuous development of product innovation marketing 50 countries or regions in the world, research and development and production technology gradually mature in the world occupies an important role in the field of step by step. In order to better meet the diverse needs of customers and provide more professional and timely technical service, the company has been set up factories in zhejiang jiaxing in 2008 and for the Chinese market trend of the development of optimal design of the product, the omni-directional service automation machinery manufacturing in China. The main means of stepper motor driver are single voltage driving mode and the driving mode of high and low voltage, single voltage driving mode mainly refers to the process, the motor winding work only in one direction for winding the power supply voltage. High and low voltage driver is to make electricity when winding can quickly reach the set current, when the power winding current rapid failure is zero, but also has high efficiency, the high and low voltage drive mode. High and low voltage driver in the forefront of conduction in the forefront of high voltage power supply to improve the current rate of climb, after the in front to maintain the low voltage winding of electric current. High and low voltage driver can achieve good high frequency characteristics, but because of the high pressure pipe conduction time constant, at low frequency, winding won too much energy, easy to cause oscillation. But by changing the high pressure pipe conduction time to solve the problem of low frequency oscillation, the voltage control circuit is complex, however, lower reliability, once high pressure pipe is out of control, will be for damage to the motor current is too big.
