Planetary gearboxes are known for their high torque capacity, thanks to the load sharing among multiple planets, which enhances stability and durability. They also boast excellent efficiency, with minimal power losses, achieving transmission efficiencies of up to 98% in the first stage.
These gears are highly efficient and offer a high power density compared to other gear types due to their compact design. The inclusion of an external ring gear further reduces the overall size and weight of the gear system.
Jkongmotor specializes in manufacturing stepper motors and brushless DC motors with over 15 years of experience. We also supply worm gearboxes, planetary gearboxes, brakes, encoders, drivers, integrated servo motors, and other motor-related products. Welcome to inquire with us.
