In the European smart home market, smart lock systems require motors that operate within 3V–6V while delivering stable torque and smooth motion.
A standard brushed DC motor (>3000rpm) is not suitable. The N20 DC gear motor, with a compact 12mm design, reduces speed to 10–300rpm and provides higher torque, making it an ideal smart lock motor solution.
Speed: 10–30rpm
Voltage: 3V–6V
Output: high torque
Low speed ensures smooth operation, while high torque guarantees reliability under load.
10–20rpm: high resistance locks
20–30rpm: standard locks
A high torque gear motor for door lock ensures stable operation even under friction or wear.
Supports 3V / 4.5V / 6V / 12V
Minimum recommended: ≥3V for startup stability
12mm compact size
D shaft for anti-slip transmission
Gearbox for torque multiplication
Different locks require different parameters:
Light load: 20–30rpm
Heavy load: 10–20rpm
Fast response: >50rpm
GA12-N20 supports customization:
Voltage: 3V–12V
Speed: 10–300rpm
Torque: optimized per load
This makes it ideal for custom DC gear motor for smart lock OEM projects.
What applications is it suitable for?
Smart locks, multi-point locks, electronic locks
Why not use a standard DC motor?
Too fast (>3000rpm) and low torque
How to choose RPM?
Higher load → lower speed → higher torque
What is the benefit of D shaft?
Prevents slipping under torque
Different smart lock systems require different RPM, torque, and voltage.
