Stepper Driver Principle Stepper Motor Driver Selection
A stepper driver is an actuator that converts electrical pulses into angular displacement. When the stepper driver receives a pulse signal,
it drives the stepper motor to rotate a fixed angle (called the “step angle”) in the set direction, and its rotation runs step by step at a fixed angle.
By controlling the number of pulses, the angular displacement can be controlled to achieve accurate positioning; At the same time, the speed
and acceleration of the motor can be controlled by controlling the pulse frequency, thus achieving the purpose of speed regulation and positioning.
Widely used in high-resolution large and medium-sized CNC equipment such as carving machines, crystal grinding machines, medium-sized
CNC machine tools, EEG embroidery machines, packaging machinery, fountains, dispensing machines, cutting and feeding systems, etc.
It is a power amplifier that can operate a stepper motor. It can convert the pulse signal sent by the controller into the angular displacement of the
stepper motor. The motor speed is proportional to the pulse frequency, so controlling the pulse frequency can accurately adjust the speed,
and controlling the number of pulses can accurately locate.
Principle of stepper driver
1. Constant current drive
Stepper Driver Principle Stepper Motor Driver Selection
The basic idea of constant current control is to control the conduction time of MOSFETs in the main circuit, that is, to adjust the pulse width of
MOSFET trigger signals, in order to achieve the goal of controlling the output driving voltage and thus controlling the motor winding current.
2. Unipolar drive
Unipolar and bipolar are the two most commonly used driving architectures for stepper motors. The unipolar driving circuit uses four transistors
to drive the two phases of the stepper motor. The motor structure, as shown in Figure 1, includes two sets of coils with a center tap.
The entire motor has six wires connected to the outside world. This type of motor is sometimes referred to as a four phase motor,
but this term can be confusing and incorrect because it actually only has two phases. The precise description would be a dual phase six wire stepper motor.
Although the six wire stepper motor is also known as a unipolar stepper motor, it can actually use both unipolar and bipolar driving circuits simultaneously.
