Typical Applications
The application fields of 8mm miniature stepping motors include but
are not limited to:
Smart security products: 8mm stepping motors are widely used in
security cameras, CCTV cameras and intelligent locks for their high
torque and precision. They can achieve precise rotation and
positioning needed by these devices.
Camera lenses: Thanks to their compact size and stable performance,
8mm stepping motors can precisely rotate and adjust camera lenses
to achieve auto-focus functions. They are key components inside
DSLR lenses, lens modules and lens turrets.
Wearable devices: As wearable technology develops, there is an
increasing demand for small size and low power motors. The 8mm
stepping motor, with its miniature size and efficiency, can power
rotating parts in wearable gadgets like smartwatches, AR glasses,
robotic limbs, etc.
Door locks: The high torque performance of 8mm stepping motors
enables them to repeatedly drive locking mechanisms of smart door
locks at a precise angle. This ensures smooth and accurate locking
and unlocking operations.
due to their small size, low power consumption and precise
positioning capability, 8mm stepping motors have found wide use in
various applications requiring compact motors with stable
performance, especially in the fields of smart home, IoT, robotics
and automation.

Competitive Advantage
Small size: At only 8mm in diameter, these motors are remarkably
compact compared to standard sized motors. Their small size makes
them suitable for applications where space is limited.
Low power consumption: Due to their simple and miniaturized
structure, 8mm stepping motors consume very little power, This low
power draw enables longer battery life in portable devices.
Precise positioning: Stepping motors achieve positioning by
receiving stepping pulses. The 8mm motors can offer high stepping
angles from 0.9 to 1.8 degrees, realizing precise rotation and
accurate positioning.
Easy to control: These motors are driven by open-loop control,
meaning they can be easily controlled with a simple logic signal
from a microcontroller. No feedback mechanism is required. This
makes their control simple and cost-effective.
Stable performance: Due to their sturdy and robust construction,
8mm stepping motors can deliver consistent performance over long
usage times and under various conditions.
the key benefits of 8mm stepping motors lie in their ability to
offer high torque and precise positioning within an extremely
compact package. Their low power consumption, easy controllability
and stable performance further enhance their suitability for
miniaturized applications where space and efficiency are at a
premium. These features make them ideal choices for industries
focusing on size reduction and integration.
