Many occasions have applications, such as office automation (printers, copiers, scanners, etc.), line cutting table, drag, hair grafting machine workbench (pore positioning), packaging machine (fixed length). There are ATM machines, inkjet printers, lettering machines, photo machines, spraying equipment, medical instruments, precision instruments, industrial control systems, robots and other fields.The utility model is especially suitable for application occasions with stable running, low noise, fast response, long service life and high output torque.
Stepper motors are widely used in many kinds of equipment for motion control. For example, from the joints of complex robots, to the household air conditioning shutter control.The main characteristic of stepper motor is that each pulse changes a step, so the positioning accuracy is higher than other motors, and the drive control is simple, and the overall cost is low. For the control system in the digital age, the stepping motor belongs to the digital motor, especially the single chip microcomputer, so it is used more and more widely. In many places, other motors, such as servo motors, have been replaced.
1. What is a direct current motor?Answer: the output or input of DC motor rotating motor, referred to as DC motor2. What is AC motor?Answer: the output or input of alternating current energy of the rotating motor, called AC motor.3. What is a stepper motor?Answer: stepper motor is an electric pulse into angular displacement of the implementation of the mechanism. Generally speaking, when the stepping driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (and step angle) in the set direction. You can control the number of pulses to control the amount of angular displacement, so as to achieve the purpose of accurate positioning; at the same time, you can control the pulse frequency to control the motor rotation speed and acceleration, so as to achieve the purpose of speed. There are three kinds of stepper motors: permanent magnet (PM), reactive (VR) and hybrid (HB). Permanent magnet stepper usually two-phase torque and smaller step angle is 7.5 degrees or 15 degrees; the reaction is generally three-phase stepper can achieve high torque output, the step angle is generally 1.5 degrees, but the noise and vibration are large. In Europe and the United States and other developed countries, in 80s has been eliminated; hybrid stepping refers to the combination of permanent magnet and reaction advantages. It is divided into two phases and five phases: two phase stepping angle is generally 1.8 degrees, while the five phase stepping angle is generally 0.72 degrees. This stepper motor is most widely used.
