The RS-390A permanent magnet DC motor has high efficiency and stable output performance. At 12V DC voltage, the no-load speed reaches 7300 rpm and the stall torque is 550 g⋅cm, which meets the torque and speed requirements of light-load systems.
To ensure long-term reliability, the motor improves heat dissipation and wear resistance through the use of F-class enameled wire, a carbon steel shaft, and durable magnetic materials. With a compact diameter and a lightweight design of approximately 87.5 g, the motor is easy to integrate into cordless power tools, small vacuum cleaners, and other applications where size, endurance, and low noise are essential.
