Product introduction
The BLD-300B brushless DC motor driver is independently developed by our company.
High-tech products driven by medium-power low-voltage brushless DC motors. The brushless DC
The machine driver adopts a cost-effective low-cost solution, which is mainly used in various automatic
Automation control equipment, such as conveying equipment, medical equipment, packaging machinery, food machinery,
Fitness equipment, teaching equipment, garden machinery and many other fields. This driver is suitable for
The speed regulation of the three-phase sine wave DC brushless motor with a rate of 48V440W and 24V300W
Section, can provide external potentiometer speed regulation, external analog voltage speed regulation, host computer (PL
C, microcontroller, etc.) PWM frequency speed regulation and other functions. At the same time, the drive has a large rotation
Torque start, quick start and braking, forward and reverse switching, combination of manual and automatic speed regulation,
Abnormal alarm signal output and other characteristics.

Frequently Asked Questions
1. Q: How can I get started as soon as I use this controller for the first time?
A: After connecting the power cable, motor phase cable and Hall cable correctly, ensure that the motor is no-load and other interfaces are suspended, use internal speed regulation, and accelerate slowly. After the motor rotates correctly, test the functions such as enable, direction, and external speed regulation in turn. If you are unfamiliar with this product, you should test it for the first time before installing it in the actual situation.
2. Q: What is the impact of reverse power connection?
A: It will burn the drive.
3. Q: After the drive works for a long time, the casing is hot, is it normal?
A: It is normal, under normal temperature the case will not affect the performance when the temperature reaches 90 degrees.
4. Q: The power indicator light is on, but the motor does not rotate and vibrates. What is the reason?
A: It may be that the phase wire and the Hall wire are wrong, please re-power the test after correct wiring according to the motor manual.
5. Q: Can I adjust the speed of my motor to 6000 with this controller?
A: The maximum speed of the brushless motor is the parameter of the motor itself, and the controller can control the motor at the maximum speed of -0-.
6. Q: Would you like to add some functions or do new product development on this driver, is it possible?
A: Yes, please contact our company.
7. Q: Is it possible to connect a low-voltage brushless motor?
A: No
