Frequently Asked Questions (FAQ)
Q: What is the main advantage of this 130mm bldc motor?
A: The 130ZW3S is designed for maximum power and torque in a 130mm frame. It is built for high-power, continuous-run applications (up to 2000W) where efficiency and high torque are critical. This makes it suitable for tasks far beyond the capability of a stepper motor.
Q: What is the benefit of the high voltage (up to 310V) capability?
A: The high voltage option (like the 310V models) allows this 130mm brushless dc motor to achieve its full power rating (over 1500W) at a lower current. This reduces heat, allows for thinner cables, and makes it compatible with high-voltage industrial AC servo drivers.
Q: What kind of driver does this bldc motor require?
A: This 130ZW3S motor requires a compatible high-power BLDC motor driver. Given its size, it’s almost always paired with a high-voltage driver. Our technical team can help you select the precise driver to match your voltage and performance needs.
Q: Is this motor suitable for precision control?
A: Absolutely. When ordered with an optional encoder, this 130mm brushless dc motor becomes a complete high-torque servo motor, perfect for precision positioning and velocity control in heavy-duty applications.
