Import 20mm Geared Stepper Motor 2 Phase 4 Wire — Buy in wholesale FOB from Supplier in China

The SM20-020L is a compact 20mm diameter geared stepper motor operating on a 2-phase 4-wire bipolar drive configuration. This motor features a phase resistance of 20Ω ± 10% measured at 25°C, with a rated current of 100 mA per phase. The maximum starting frequency reaches 800 pulses per second (pps) while the maximum response frequency extends to 1000 pps, enabling precise speed control in automated systems. The motor employs 2-2 phase excitation method and achieves a pull-out thrust exceeding 260g at 800 pps, providing sufficient torque for small precision applications.

The motor is constructed with Class E insulation rated for one second withstand voltage of 100V AC, and insulation resistance of 50MΩ at 500V DC. The operating temperature range spans from 0°C to 55°C, suitable for indoor electronic equipment environments. The housing and gearbox materials follow standard specifications for miniature precision motors, typically utilizing metal gears and bearing systems designed for continuous duty operation. The VIC-TECH brand designation indicates the supplier's proprietary motor design, and the product carries RoHS certification ensuring compliance with European hazardous substance restrictions.

This geared stepper motor serves precision medical equipment including saliva analyzers and blood analyzers, industrial applications such as welding machines and fiber fusion splicers, plus security systems and digital electronics. Buyers typically include OEM manufacturers requiring compact motion control for portable devices, medical instrument producers needing reliable stepping performance, and automation system integrators. Minimum order quantity is 1 unit with supply capacity of 10,000 units per month, and standard export packaging is available with customization options.
