Shenzhen four macro technology co. , LTD. (Shanghaiszzhenhe技术有限公司,Ltd . )Founded in 1980 in hsinchu city of shenzhen, is a professional engaged in electronic automatic control research and development and manufacturing technology companies. We based on customer demand for continuous improvement innovation, and strive to provide a full range of automation solutions and products to meet today's more and more high automation production requirements. How to the stepper motor speed stepper motor is a pulse signal into angular displacement or linear displacement. One is the characteristic of overload. Its speed is not affected by the size of the load, unlike ordinary motor, when the load increase would be a drop in speed, stepping motor when using all has the strict request to the speed and position; Second, the control is convenient. Stepper motor is a 'step' as the unit of rotation, the obvious features of digital; 3 it is the whole machine structure is simple. The traditional mechanical speed and position control structure is more complex, adjustment difficulties, using stepper motor, makes the whole machine structure is simple and compact. Speed motor speed is converted into voltage, and passed to the input as a feedback signal. Speed motor is a kind of auxiliary type, installed at the end of the common dc motor speed motor, by speed motor feedback voltage to the dc power supply, to achieve the purpose of the dc motor speed control. 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 products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
