Stepper motor driver is an actuator that converts electric pulse into angular displacement. After receiving the pulse signal, the stepping driver drives the stepping motor to rotate according to the set direction - fixed angle (called "step angle"), and its rotation steps at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning; At the same time, the speed and acceleration of motor rotation can be controlled by controlling the pulse frequency

To achieve the purpose of speed regulation and positioning.

What types of stepper motor drives are available?

Stepper motor driver is an actuator that converts electric pulse into angular displacement. When the stepping driver receives the pulse signal, it drives the stepping motor to rotate a fixed angle (called "step angle") in the set direction, and it rotates to run gradually at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning; At the same time, the speed and acceleration of motor rotation can be controlled by controlling the pulse frequency, so as to achieve the goal of speed regulation and positioning.

Stepper motor drive full step drive

In the actual operation through stepping, the same control of stepping motor can match the full / half stepping motor driver and market segmentation driver, but the teaching effect of actual operation management is also different. Stepper motor drive

The two electromagnetic coils of the two-phase stepping motor are excited according to the single pulse / azimuth command. Under each single pulse of this drive development mode, i.e. 1.80 degrees, the motor will move at a basic transverse angle.

Stepping motor drive over ore pool drive

The electromagnetic coil is driven by single-phase Qingyuan servo motor and two-phase excitation current stepping motor. 90 degree cross rotation method. All scooter drivers are driven by the driver's dial switch to select full stepping on the Minepit. Compared with the overall step type,

The ore pool type has the advantages of double precision, high speed and low vibration. Therefore, in the specific application of the whole / multi ore pool driver, the multi ore pool formula is generally selected.

Stepper motor drive setting subdivision

The subdivision drive mode set by the driver has two advantages: high precision level and low speed and low vibration. Subdivision stepper motor drivers are usually used for low-speed operation or stepper applications with accuracy less than 90 degrees. It can divide the distance between step angles into several

The subdivision part is realized by accurately controlling the current of the two electromagnetic coils of the motor according to sinusoidal and cosine steps.

The drive system and control system of mechanical equipment are generally composed of PIC, motor driver and actuator motor. The motor is generally divided into servo motor, stepping motor and parallel motor. The working mode of stepping motor driver is introduced. Stepper motor drive

The characteristics of the system software are the characteristics of the stepping motor and the quality of the stepping motor driver. In the application scenarios that require high precision, large vibration and fast feedback data information, the bus stepping motor driver of sampling system has also been widely used

And recognition.

As an open control system, stepping motor has essential connection with modern digital control technology. At present, stepping motor is widely used in national digital control system. With the emergence of all digital AC servo system, AC servo is introduced.

The machine is more and more widely used in digital control system. In order to adapt to the development trend of digital control, pacemakers or as execution engines are mostly used.
