从China供应商批发进口25mm Dc Gear Motor From Kegu Motor — FOB条款

The 25 mm DC gear motor from Hong Kong Dong Hui Motor Industrial Co., Ltd. is a compact brushed or brushless DC motor paired with a reduction gearbox in a 25 mm diameter frame. The unit delivers increased torque at reduced output speed through precision-matched metal or sintered bronze gearing, with voltage options typically spanning 6 V, 12 V, or 24 V DC depending on winding configuration. Stall torque for motors in this frame size generally falls between 1 kgf.cm and 10 kgf.cm, with no-load speeds from 15 rpm to 300 rpm after reduction. The motor is designed for continuous duty in robotics, medical devices, and automated equipment where space constraints dominate layout decisions.

Construction centres on a steel or nickel-plated housing with a D-cut output shaft for secure coupling, while the gear train employs hardened steel pinions and polymer or bronze planet gears depending on torque class and noise requirements. Typical backlash in a 25 mm planetary stage ranges from 1° to 3°, acceptable for conveyor drives and valve actuators but requiring confirmation for precision positioning. The motor windings use class F or H insulation (standard for small DC motors), with commutator and brush materials selected for life ratings between 1,000 and 3,000 hours under rated load. Noise levels below 45 dB at 30 cm are common for helical or skewed tooth variants, though exact dB ratings for this unit should be requested from the supplier.

Buyers integrate this motor into automated dispensing systems, electric locks, and AGV wheel drives where the 25 mm form factor fits standard NEMA 14-equivalent envelopes. The supplier, based in Shenzhen, Guangdong, lists a harbour trust tier and shows zero response rate on the platform, so direct outreach is essential to confirm current production capacity and sample availability. Standard packaging is typically foam-lined carton with anti-static bagging; confirm whether export carton labelling and HS code 8501.10 classification documentation are provided. Lead time, MOQ, and exact unit pricing are not stated in the source data and must be negotiated directly.

Hong Kong Dong Hui Motor Industrial Co., Ltd. maintains its registered address in Shang Liao Industrial Zone, Shajing, Shenzhen, Guangdong Province, postal code 518000, with operations centred in one of China's principal electronics manufacturing corridors. The supplier holds a harbour trust tier on the platform, indicating a baseline verification level, though the response rate is recorded at 0.00 percent with zero average response hours, which signals that direct communication channels outside the platform may be necessary to secure timely replies. The company specialises in small DC motors and gear motor assemblies, with the 25 mm gear motor representing a standard frame size in its catalogue.

The listing does not disclose factory size, year of establishment, revenue, employee count, or specific clientele, and no ISO 9001, CE, or RoHS certificates are attached to the source data. Buyers should request quality system documentation and factory audit reports during initial engagement. The supplier's proximity to Shenzhen port facilitates FOB Shenzhen shipment, though Incoterms, payment methods, and credit terms remain unconfirmed without direct negotiation. There is no mention of in-house R&D capability or custom winding services, so engineering support for ratio or voltage modifications should be explicitly discussed.
