For many years, stepper motors have been used in many fields. With the trend of miniaturization, computer control and cost reduction, hybrid stepper motors are increasingly used. Especially in recent years, the use of stepping motors has rapidly expanded and these sophisticated and reliable motors can be found in many fields, including blood analyzers and other medical instruments, stage automation lighting, imaging equipment, HVAC equipment, valve control, Printing equipment, XY platform, integrated chip manufacturing, testing equipment. In order to quickly allow all users further stepper motor has a common understanding, the author finishing the following technical terms for your reference: Stepping: The angle at which the rotor rotates when it receives a pulse. For linear motors, the step is a straight line. Step angle: the rotor produced by each step of rotation, measured in degrees. Rotation per revolution per week or per revolution: Total number of steps required for the rotor to rotate 360 ​​°. Linear step increments (or steps): The linear displacement of the lead screw per one rotor revolution. Torque: The sum of drag torque and moment of inertia. What is the torque or torque? Refers to the motor winding in the static electricity does not turn, can make the motor rotation in the output shaft torque required. All manufacturers of motor electrical parameters will be marked with this parameter, but this parameter but for the motor selection or practical use of no significance. What is dynamic torque or dynamic torque? Refers to the motor in the relative speed of the output torque. Dynamic torque can be expressed by PULLIN or PULLOUT. This parameter is the core index of motor selection. Because the stepper motor does not have the power to say, nor is it a constant torque motor, it is very important to judge the output dynamic torque of the motor based on the motor's frequency characteristic diagram. PULLOUT: The maximum torque the motor can produce at constant speed. Because the speed is constant, there is no moment of inertia either. Week when the rotor internal kinetic energy and inertia load so that the pulling torque increases. PULLIN: The heart must overcome the accelerating torque of the rotor inertia, as well as the externally connected fixed load and various frictional torques during acceleration. Therefore, the pull-in torque is usually less than the pull-out torque.
