2 Phase Stepper Motor Driver Will Affect the Quality of Work
A stepper motor is an actuator that converts electrical impulses into angular displacement. Stepper motor can not be directly connected to the power frequency AC or DC power supply, but must use a special driver, as shown in figure, it consists of pulse generator control unit, Power Drive unit, protection unit, etc. . The two units enclosed by the dotted line in the drawing can be realized by microcomputer control. In order to improve the high frequency response of the drive system, the step-up power drive interface can be used. The interface is linear to the voltage supplied by the windings and the operating frequency of the motor. Its main circuit is actually a switching power supply, which uses a frequency-to-voltage converter to convert the frequency of the driving pulse to a DC level, and uses this level to control the input of the switching power supply, this constitutes a power driver interface with frequency feedback. In layman's terms: when the 2 phase stepper motor driver receives a pulse signal, it drives the stepper motor to rotate at a fixed angle (stepping angle) in a set direction. Stepper motor is a kind of electrical pulse into angular displacement of the actuator. In layman's terms: when the 2 phase stepper motor driver receives a pulse signal, it drives the stepper motor to rotate at a fixed angle (stepping angle) in a set direction. You can control the number of pulses to control the angular displacement, so as to achieve accurate positioning; at the same time, you can control the pulse frequency to control the speed and acceleration of motor rotation, so as to achieve speed control purposes. However, 2 phase stepper motor driver directly affects the quality of its work, the specific analysis is as follows:
Nowadays, the development of manufacturing technology can not be separated from stepper motors everywhere. The production procedure of Stepper Motors is a very complicated matter. It requires production and manufacturing personnel not only to understand the mechanical and motor industries, the stepping motor controls the angular displacement by controlling the number of pulses, so as to achieve the goal of accurate positioning At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, so that the speed can be adjusted. 2 phase stepper motor driver is a kind of electrical pulse into angular displacement of the actuator. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate at a fixed angle in a set direction. The rotation of the stepper motor is done step by step at a fixed angle. How to match the driver, 57HB76 stepper motor minimum current can be 0.6 a maximum current can be so large 6.0 A. That would be inappropriate. Therefore, specifications, torque, speed, current, voltage, application environment is an important reference, step motor is divided by power so that the driver can not be divided by power. Because general-purpose drives are now almost always subdivided drives, the problem of subdividing can be ignored. The quality of the 2 phase stepper motor driver plays a decisive role in the quality of the stepper motor, stepper electronics has solved a big problem of the mechanical work in our country's manufacturing industry, and has played a driving role for our country's motor driver industry.
