The quality of stepper motor driver directly affects its working quality

A stepper motor is an organization that converts electrical pulses into angular displacement. Stepper motor drive Stepper motor can not be directly connected to the industrial frequency AC or DC power supply work, and must use a special driver, as shown in the figure, it is composed of pulse generation control unit, power drive unit, protection unit and so on. The two units enclosed by dotted lines in the diagram can be realized by microcomputer control. Step motor drive in order to further improve the high frequency response of the drive system, the frequency and voltage boost power drive interface can be adopted. The voltage provided by the interface pair windings is linear with the operating frequency of the motor. Its main circuit is actually a switching regulator power supply, the use of frequency-voltage converter, the frequency of the driving pulse into dc level, and this level to control the input of switching regulator power supply, which constitutes a power drive interface with frequency feedback. A popular point: when the stepper motor driver receives a pulse signal, it drives the stepper motor to rotate a fixed Angle (Angle) according to the set direction (i.e. the step Angle). You can.. Stepper motor is an actuator that converts electrical pulse into angular displacement. In popular terms: when the stepper motor driver receives a pulse signal, it drives the stepper motor to rotate a fixed Angle in the set direction (that is, the stepper Angle). You can control the angular displacement by controlling the number of pulses, so as to achieve the purpose of accurate positioning; At the same time, you can control the speed and acceleration of motor rotation by controlling the pulse frequency, so as to achieve the purpose of speed regulation. However, the quality of stepper motor driver directly affects its job quality, and Analyse Analyse is introduced as follows:

Nowadays, the development of industrial Technology in manufacturing is inseparable from stepper motors. The procedure for the production of stepper motors is a very complicated thing, which requires the production personnel not only to understand the machinery and motor industry, Also involves a lot of electronic and calculate machine Knowledge, stepper motor is mainly through the control of pulse number to control the angular displacement, so as to achieve the purpose of accurate positioning; At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation. The stepper motor driver is an actuator that converts electrical pulse into angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to turn at a fixed Angle (called the "step Angle") in a set direction, and its rotation moves step by step at a fixed Angle. If we consider how to configure the driver unilaterally from the current, the small current of 57HB76 stepper motor can achieve 0.6A and the large current can achieve 6.0A, which is such A big gap. That would certainly be inappropriate. Therefore, specifications, torque, speed, current, voltage and application environment are important reference bases. Stepper motors are distinguished by power, so drivers cannot be distinguished by power. Because today's general-purpose drives are almost always subdivided drives, the subdivision problem can be ignored. Stepping machine drive in good or bad for the work quality of stepping machine plays a decisive factor, stepping machine electronics to solve a big problem in China's manufacturing machinery work, for China's motor drive industry plays a driving role.
