Product Description

Wide Voltage 5-24V 20mm 20BY45 Permanent Magnet Stepper Motor 18° Step Angle Versatile Use

The 20BY45 isn’t just a stepper motor—it’s a precision-engineered solution for demanding applications. With a 20mm diameter and 18° step angle, every component is forged from precision molds, delivering unmatched stability, ultra - low detent torque, and industry - leading efficiency compared to generic alternatives.

Built to Endure & Impress

Motor casings and all metal parts undergo eco - friendly plating, ensuring a sleek, durable finish that thrives in harsh environments—no compromise on aesthetics or resilience.

Versatile & Customizable

Tailored for:

Precision medical devices (reliability in critical care)
Smart door locks (secure, smooth actuation)

Input options go beyond standard: The default light - type connector adapts to FPC cables, custom PCBs, or unique interfaces—we mold solutions to your design. Need a full drive system? We integrate it seamlessly.

Decades of Expertise, Yours to Leverage

Our team brings 10+ years of micro - motor R&D and manufacturing mastery. Whether you need tweaks to the 20BY45 or a ground - up custom design, we turn “special requests” into reality—fast.

Choose 20BY45 for a motor that’s as adaptable as your innovation.
