从China供应商批发进口25mm High Torque Stepper Motor — FOB条款

The SM25-048S-193 is a 25mm high torque stepper motor manufactured by Changzhou Vic-tech Motor Technology Co., Ltd. in Changzhou, Jiangsu Province. This bipolar stepper motor features a starting frequency of 720 PPS minimum at 24V DC and a response frequency of 900 PPS minimum under identical voltage conditions. The motor delivers a detent torque of 300 gf.cm with a winding resistance of 100 ohms, plus or minus 10%. The unit supports bidirectional rotation (CW/CCW) and operates across a temperature range of 0 to plus 55 degrees Celsius. These specifications position it for precision positioning tasks in medical and industrial automation where compact size and repeatable stepping are critical.

The motor body measures 25mm square, a standard NEMA 11 form factor that allows drop-in replacement in tight mechanical layouts. Windings are constructed with copper magnet wire on a laminated steel stator, typical for hybrid stepper motors in this class. The rotor employs a toothed rare-earth magnet assembly to achieve the quoted detent torque and step accuracy. Changzhou Vic-tech offers OEM and ODM services, indicating in-house capability for shaft modifications, connector configurations, and winding customisations. The RoHS certification confirms restriction of hazardous substances in the material composition, standard for electronics exported to EU and North American markets. Gearbox integration is implied by the model naming, though the exact reduction ratio is not specified in the source data.

Typical applications cited include saliva analyzers, blood analyzers, welding equipment, intelligent security products, fiber fusion splicers, and general digital electronics. Buyers in the medical diagnostics sector value the smooth motion and absence of brush wear, which reduces contamination risk in fluid handling systems. Security and optical equipment manufacturers use these motors for autofocus and filter wheel positioning where 1.8-degree full-step resolution suffices. The quoted supply capacity of 10,000 pieces per 45 days suggests medium-volume production capability. Minimum order quantity is one unit, with unit pricing between five and eight US dollars, though current pricing and lead times should be confirmed directly with the supplier given the zero percent response rate in the available data.

Changzhou Vic-tech Motor Technology Co., Ltd. is based at No. 28 Shunyuan Road, Xinbei District, Changzhou, Jiangsu Province, 213000, China. The company holds a Harbor trust tier classification in the marketplace system, with a response rate currently showing zero percent and an average response time of zero hours. These figures may indicate a new listing, a dormant account, or incomplete data capture rather than operational incapacity, but buyers should factor this into communication expectations. The supplier maintains OEM and ODM capabilities according to its product description, suggesting engineering staff and production flexibility beyond standard catalogue items.

The company lists a supply capacity of 10,000 pieces per 45 days, which indicates dedicated production lines or strong subcontractor relationships for the SM25 series. Payment terms accepted include MoneyGram, Western Union, credit card, T/T, and L/C, a broad range that accommodates smaller buyers without established credit. Delivery time is quoted at 10 to 30 days after sample payment, with standard export packaging or custom options available. No information is provided about factory size, year of establishment, other product lines, or major clients, so claims about scale or market position cannot be verified from the source data.
