步进电机概述 中英文资料对照外文翻译文献综述 外文文献： Knowledge of the stepper motor What is a stepper motor： The stepping motor as executing components, electromechanical integration is one of the key products, widely used in a variety of automatic control systems. With the development of microelectronics and computer technology, the stepper motor demand grow with each passing day, has been applied in various fields of the national economy. Stepping motor is a kind of electrical pulses into angular displacement of the implementing agencies. When stepping drive receives a pulse signal, it drives stepper motor rotate in the direction set by a fixed angle ( called the step ), it is the rotation at a fixed angle step by step operation. The number of pulses to control the amount of angular displacement through the control, so as to achieve the purpose of accurate positioning; also can control the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of speed. Special motor stepper motor control can be used as a, using its no accumulation of error ( accuracy of 100% ) characteristics, widely used in all kinds of open-loop control. Now more commonly used step motor comprises stepper motor ( VR ), permanent magnet stepper motor ( PM ), hybrid stepping motor ( HB ) and single-phase stepping motor. Permanent magnet stepper motor for general two-phase, torque and small volume, the step angle is 7.5 degree or 15 degree; Reaction stepping motor is generally three-phase, can achieve a high torque output, step angle is 1.5 degrees, but the noise and vibration are great. The rotor magnetic circuit made of soft magnetic material reaction stepper motor, a multi-phase excitation winding stator, using magnetic - 1 - torque changes. Hybrid stepping motor is mixed the advantages of permanent magnet type and reaction type. It is divided into two phase and five phase: two-phase stepper angle is 1.8 degree and five phase stepper angle is 0.72 degrees. Application of the s
