2 phase nema 23 motor driver adopts high frequency bipolar subdivision current modulation, which greatly improves the stepping resolution of stepping motor, and has the advantages of high torque, low vibration and high reliability.
It can be used to drive 4, 6 and 8 wire two-phase hybrid stepping motors with a step angle of 1.8 degrees and 0.9 degrees. When selecting a motor, it is mainly determined by the torque and rated current of the motor. The torque is mainly determined by the size of the motor. Larger motors have higher torque. The current is mainly related to the inductance, and the small inductor motor has good high-speed performance, but the current is large.
Each time the driver receives a CP pulse, it drives the stepper motor to rotate by one step angle (subdivided into a subdivided step angle). The frequency change of the CP pulse changes the speed of the stepping motor at the same time. By controlling the number of CP pulses, the stepper motor can be accurately positioned. This makes it easy to achieve the purpose of stepping motor speed regulation and positioning.

1. We have adopted advanced technology to greatly improve the stability of the intermediate frequency and anti-resonance, so that there is more torque output at high speed.
2. 2 phase nema 23 motor driver can keep the motion smooth under low subdivision.
3. Its dynamic filtering of the speed and direction signals can reduce the motion transients of the motor and mechanical system, and the motor runs more smoothly, while also reducing mechanical wear.
4. When the system is connected to the power supply, the drive can automatically detect the motor parameters (such as resistance and inductance), and optimize the system performance based on this parameter.
