SigGear provides micro gear motors, miniature planetary gearboxes, and compact drive solutions for micro mechanical, Mechanical grippers, smart hardware, medical devices, laboratory automation, optical equipment, and precision mechanisms.
For compact mechanical and small motion systems, engineers often need a drive solution that combines small size, stable output torque, low noise, flexible gear ratio, and easy mechanical integration. SigGear can support micro drive solutions as small as 6mm, as well as 6-42mm miniature and compact planetary gear reducers for different torque and space requirements.
Why Micro Mechanical Need Micro Gear Motors
Micro machines and miniature mechanisms often have very limited installation space. A motor alone may rotate too fast and provide insufficient output torque, so a micro gearbox or micro gear motor is used to reduce speed and increase torque.
A suitable micro gear motor helps improve:
Compact mechanism design
Stable low-speed movement
Output torque
Motion repeatability
Gripping or driving force
Low noise operation
Mechanical integration speed
Prototype development efficiency
