28BYJ48 28mm 4-Phase Stepper Motor - 12V 1:64 Reducer for Bathroom Fixtures
This 4-Phase 28mm geared reducer stepper motor, model 28BYJ48, is tailored for bathroom applications with its 12V voltage and 1:64 reduction ratio. Designed to thrive in the humid environment of bathrooms, it combines compact 28mm sizing with reliable performance, making it ideal for toilet lid lifters, automatic soap dispensers, and other smart bathroom devices.
The 1:64 reduction ratio ensures precise, slow-speed movement—critical for smooth operation in bathroom fixtures where gentle motion is key. As a 4-phase stepper motor, it delivers consistent torque to handle repetitive tasks, while the geared reducer structure enhances durability, even with frequent use.
Whether integrating into new bathroom automation systems or upgrading existing setups, this 28BYJ48 motor offers a perfect blend of size, power, and precision, specifically optimized for the unique demands of bathroom environments.
