步进电机的认识(国外英文资料) The stepper motor from September 1, 2009 until now, I have learned more than two months, I feel like I have seven or eight of the stepper motor control, but also to the bottleneck stage, because I felt more boring now, and dont know what you need look, I understand that I should go out to see the world now, or touch the stepper motor, never put the theories into practice, and the theory of something just a little bit, but after the divergence to the practical application, there will be a lot of problems coming, we in sales, is to bring those things into reality may have all learned it. The following is my own point on the stepper motor to understand, I hope you can give me prawns, put forward some suggestions for study, I dont want to keep on like this, or I continue to see the theory as well as the progress of space, and every day there is a visible progress, either let me face the reality, to meet N how to solve the problem, I dont want to stay in this state of muddle along without any aim!! Definition: I have access to are hybrid stepper motor, its positioning accuracy, low price, is a pulse into the implementation of the motor corresponding angular displacement of the upper system, each to a pulse motor, it is according to the given direction (the actual step by step angle, will be back mentioned). Structure: hybrid stepping motor mainly consists of two parts, stator and rotor. The stator has windings that generate a rotating magnetic field when it is energized. The rotor is a permanent magnet with a shaft. There are two bearings at the two ends of the shaft (axial or radial, I cant distinguish the name). The periphery of the rotor has a lot of small teeth, the stepper motor step angle mainly rely on these teeth to decide. The rotor surface cross pile, the angle between the two adjacent teeth, is called the motor gear angle, according to the number of beats the motor operation, can obtain the intrinsic step angle of the motor (stepping angle divi
