Frequently Asked Questions (FAQ)

What are the primary advantages of an Inner Rotor Motor?
Inner rotor motors feature a lower moment of inertia because the rotating part (rotor) is located inside the stator. This allows for extremely high rotational speeds and rapid responsiveness, making them ideal for dynamic applications like robotics and precision automation.
Does Sweg Motor provide OEM/ODM customization?
Yes, we specialize in customized solutions. We can modify motor length, shaft diameter, gear ratios, winding specifications, and IP ratings (up to IP65/IP67) to match your specific engineering requirements.
What quality certifications do your motors hold?
Our factory is ISO 9001 certified. Product-specific certifications include CE, CCC, CB, VDE, and RoHS compliance. We also perform 100% testing on noise, torque, and insulation before shipping.
What is the typical lead time for international orders?
Standard samples typically take 7-10 days. Mass production orders are generally fulfilled within 25-35 days depending on the customization complexity and order volume.
