Frequently Asked Questions (FAQ)

Q: What is the minimum order quantity (MOQ)? A: Our standard MOQ for stock NEMA 17 BLDC motors is just 1 piece for samples. Custom configurations start at 50-100 pieces.

Q: What voltage options are available? A: Standard is 24V DC. Optional voltages include 12V, 36V, and 48V DC. Custom windings for 12-60V range available.

Q: Do you provide BLDC motor drivers with the motors? A: Yes, we offer compatible drivers perfectly matched to our motors, from basic hall-effect drives to advanced FOC drives with RS485/CANopen.

Q: Can you manufacture custom brushless DC motors? A: Absolutely. We specialize in custom solutions including special windings, modified shafts, custom mounting, integrated encoders/gearboxes/brakes, special connectors, and higher IP ratings.

Q: What is the typical lead time? A: Stock models: 2-3 working days. Standard production: 15-20 working days. Custom orders: 25-35 working days for samples, then 20-30 days production.

Q: What is the warranty period? A: We provide a 12-month warranty from shipment against manufacturing defects. Designed service life exceeds 20,000 hours under proper conditions.

Q: Do your motors support speed control and direction reversal? A: Yes, with compatible drivers they support variable speed control (0 to rated speed+), CW/CCW reversal, enable/disable. Advanced drivers offer closed-loop speed regulation ±0.5% accuracy.

Q: Are these motors suitable for continuous operation? A: Yes, they are rated for continuous duty at rated torque/speed with proper mounting and heat dissipation.
