How to choose the right power supply to power the stepper motor?
The following are the key factors to consider when choosing a stepper motor power supply:
1. Power supply type: Common power supply types include switching power supply, linear power supply and battery. Switching power supplies are ideal for powering stepper motors due to their high efficiency and small size.

2. Voltage level: It is very important to choose the right voltage level. Generally, the voltage level should be higher than the rated voltage of the stepper motor to ensure that the motor can provide sufficient torque. However, too high a voltage can cause the motor to overheat. Therefore, the appropriate voltage level needs to be selected according to the motor specifications and drive requirements.

3. Current capacity: When selecting a power supply, you need to ensure that its output current capacity is sufficient to drive a stepper motor. Generally, the current capacity of the power supply should be slightly greater than the maximum current demand of the driver and motor to ensure the stable operation of the system.

In summary, when selecting a power supply for a stepper motor, factors such as power supply type, voltage level, current capacity, stability and protection function, and external conditions need to be considered. A suitable power supply will help improve the performance and stability of the stepper motor system and extend its service life.
Stepper motor power supply solution
The power supply solutions for stepper motors are as follows:
Change the direction level signal of the control system. For two-phase motors, simply swap the motor wires of one of the phases into the drive.

Adjust the wiring of the motor to change direction. Work the stepper motor in the oscillation area, first check whether the winding of the motor is connected to the drive incorrectly, and then check whether the frequency of the input pulse signal is too high and whether the frequency reduction design is unreasonable.
In addition, there are different power supply solutions such as subdivision drives.

How to choose the power supply of stepper motor?
The selection method of stepper motor power supply is as follows:
According to the rated voltage and current of the motor, the power supply is selected to ensure that the output is stable, the voltage and current are matched with the motor, and the power is sufficient.
Pay attention to the signal isolation and filtering function of the power supply to ensure the stability and anti-interference of the electrical signal.
