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.
We provide customization service on gear ratio, coil resistance,
phase number, and connector types.
Customers can customize motor’s parameter based on specific
requirement, we have 16:1 to 64:1 gear ratio for option.
