STC Group, Micro-Motors Testing


Micro-motors are small electrical motors with a maximum output capacity of 100W (watts). Micro-motors are often used in control systems for functions such as converting electromechanical signals and energy, transmitting mechanical loads, and acting as an AC and DC power supply for equipment. Micro-motors are reversible synchronous motors made up of a synchronous magnetic motor and a built-in reduction gear box to allow large torque, minimal noise, small size, light weight, convenient use, and constant speed operation. Additionally, gear boxes could be adjusted to achieve desired change in output speed and torque as well making micro-motors a popular option for daily life’s productions. 

As the demand for electrical motors and micro-motors continue to grow, extensive testing to ensure product safety and performance is required to keep pace with technical advancements and regulatory requirements.
