Automatic paper dispensers are widely used in public hygiene management and home environments due to their touch free operation and improved paper saving efficiency. With the rise of smart home devices and commercial automation, the DC gear motor used inside the dispenser has become an important component.
This article provides a science based explanation of how an automatic paper dispenser works and introduces the GA25Y370 and 25GA370 gear motors which are commonly used in dispensing machines smart home actuators and small automation systems. Popular Google keywords such as automatic paper dispenser motor, DC gear motor for dispenser, 25GA370 gear motor, mini DC motor, and custom DC motor manufacturer are naturally integrated to enhance SEO performance.
The dispenser detects hand movement through an infrared or capacitive sensor with a typical response time of around 0.5 seconds. The sensor output is processed by a control chip which activates a DC gear motor to rotate the paper roller and output a preset paper length.
Key steps include:
Sensor activation
DC gear motor transmission
Paper cutting by resistance or automatic cutter modules
Because the dispenser requires low noise high torque stable output and compact dimensions the GA25Y370 and 25GA370 motors are widely selected.
