The PM25 25mm Reduction Stepper Motor redefines precision engineering for industrial and medical devices. Its core advantage lies in subdivided step angles (via integrated gearbox) and 5 optimized reduction ratios (10–100), delivering amplified load torque and unmatched control accuracy—critical for applications like welding machines, blood analyzers, and fiber fusion splicers. Measuring just 25mm in diameter with a 15mm motor length and four gearbox options (16.0mm–20.5mm), it balances compactness with power.
Operating at 5V–24V, it offers speeds from 10rpm to 500rpm, adapting to slow, precise movements or high-speed workflows. Built with ROHS materials, it’s energy-efficient, low-noise, and low-heat, with a lightweight design for easy installation. What sets it apart? Under non-overloaded, interference-free conditions, its speed and stop position are strictly pulse-controlled—immune to load fluctuations, guaranteeing consistent results. With a motor service life of >10,000 hours and gear life of >2,000 hours, it’s a durable choice for intelligent security products, digital electronics, and saliva analyzers.
