从China供应商批发进口25mm 4 Phase 6 Wires Geared Stepper Motor — FOB条款

The SM25-048-193 is a 25 mm geared stepper motor from Changzhou Vic-tech Motor Technology, built around a 4-phase, 6-wire configuration with a phase resistance of 100 Ω ± 10%. Each phase draws 120 mA, and the motor starts reliably at 500 pps when driven at 12 V DC. Pull-in torque is rated at 400 gf.cm at 100 pps, with a holding torque of 1000 gf.cm, figures that suit it to instrument-grade positioning tasks rather than heavy-load automation. Dielectric strength is tested to 600 VAC for 1 second, and the operating temperature range spans 0 °C to +60 °C.

The 25 mm frame size places this motor in the sub-miniature stepper category, where the integrated gearbox multiplies output torque while reducing output speed for precision linear or rotary actuation. The 6-wire topology allows flexibility in drive mode, selectable between unipolar and bipolar configurations depending on the controller architecture. Standard export packaging is offered, with custom packaging available on request, a typical arrangement for laboratory and medical device OEMs who require clean-room compatible presentation. The 10000 unit monthly supply capacity indicates production tooling dedicated to this frame size.

Primary applications include saliva analyzers, blood analyzers, welding equipment, intelligent security products, fiber fusion splicers, and general digital electronics where controlled incremental motion is critical. OEM and ODM services are available, suggesting the supplier can adapt shaft geometry, leadwire length, or connector types for integrated designs. Buyers should note the 15-30 working day delivery window and confirm whether their volume justifies tooling modifications or preferential scheduling.

Changzhou Vic-tech Motor Technology Co., Ltd. is located at No. 28 Shunyuan Road, Xinbei District, Changzhou, Jiangsu Province, China, placing it within the Changzhou motor manufacturing cluster that serves domestic and export markets for precision electromechanical components. The supplier holds a Harbor trust tier on the platform, with a response rate currently showing as 0.00% and zero recorded average response hours, indicating either a newly listed profile or one that has not yet engaged through the platform messaging system.

The listing explicitly offers OEM and ODM services and cites a supply capacity of 10000 units per month, which implies dedicated production lines for this motor family rather than brokered trading. No information is provided about ISO certification, factory audit status, or years in operation, so buyers should request quality management system documentation and sample qualification data directly. Payment terms listed include MoneyGram, Western Union, credit card, T/T, and L/C, suggesting flexibility for smaller initial orders but warranting verification of escrow protections for first transactions.
