Import 35mm 4 Phase 12 V Small Stepper Motor — Buy in wholesale FOB from Supplier in China

The SM35-048L-30G is a 35mm diameter permanent-magnet geared stepper motor rated for 12V operation with a 4-phase excitation scheme. Each phase draws 400mA, with a winding resistance of 30-45 ohms depending on configuration. The motor delivers a holding torque between 3000-6000g.cm, suitable for precision positioning tasks where step accuracy matters. Its 35mm frame size places it in the small stepper category, common in compact electromechanical systems where space is constrained but controlled rotary motion is required.

The permanent-magnet rotor construction provides predictable detent torque and reasonable step resolution without the cost and complexity of hybrid designs. The gearhead offers reduction ratios from 4.5:1 to 120:1, enabling output speeds and torque profiles matched to load requirements. Total unit weight is approximately 150g, a typical value for this motor class with metal gearbox. The pull-in rate of 450pps defines the maximum step frequency at which the motor can start without losing synchronisation, a critical parameter for open-loop control schemes. RoHS compliance indicates lead-free construction suitable for electronics markets with environmental restrictions.

Applications span tap control systems, automotive air-door actuation, medical devices, and small robotic joints where incremental positioning at moderate torque is needed. OEM and ODM services are indicated, suggesting custom shaft, leadwire, and mounting configurations can be negotiated. Buyers should confirm the exact gear ratio, winding configuration, and shaft modification options required for their mechanism. The supplier lists a minimum order quantity of one unit and a delivery window of 15-30 working days, though lead times for customised variants should be verified directly.

Changzhou Vic-tech Motor Technology Co., Ltd. is located at No.28 Shunyuan Road, Xinbei District, Changzhou, Jiangsu Province, with postal code 213000. The company carries a harbor-tier trust designation on this marketplace, indicating baseline verification of business registration and existence. The listing shows a response rate of 0.00 percent and zero average response hours, which suggests the supplier has not engaged with buyer enquiries through the platform's messaging system. Buyers should therefore expect to initiate contact via external channels and allow for possible delays in communication.

The supplier's stated production capacity is 10,000 units per month for this stepper motor line. Payment terms indicated include MoneyGram, Western Union, credit card, T/T, and L/C, offering some flexibility across transaction sizes and buyer risk preferences. OEM and ODM services are advertised, implying in-house or affiliated engineering capability for mechanical customisations. The listing does not disclose factory size, year of establishment, quality management certifications such as ISO 9001, or named client references. Prospective buyers should request factory audit documentation, sample test reports for torque consistency and insulation resistance, and clarification of warranty terms before committing to volume orders.
