Geared Motor BMN04-0829

The Geared Motor BMN04-0829 is a compact and powerful solution that combines Orbray's brushless micromotor BMN04-0829 with the durable SPG04 planetary gear. This combination allows for higher torque and lower speeds, making it ideal for applications that require both precision and strength in a very small format.

The SPG04 planetary gear is designed to handle high loads and distribute torque efficiently across multiple gears, providing both high durability and smooth power transmission. The gear is available in multiple stages with reduction ratios from 4.29:1 up to a whopping 337.36:1. The efficiency varies depending on the number of stages – from 85% with one stage to 52% with four stages.

In combination with the BMN04-0829, which is powered by 3 V, the motor provides different performance profiles depending on the gear ratio. The no-load speed ranges from 7690 rpm at the lowest gear ratio down to 98 rpm at the highest. The stall torque can reach up to 5.44 mNm, making the motor suitable even for torque-intensive tasks on a micro scale.

The total length of the motor and gear varies between 14.8 mm and 18.4 mm depending on the selected gear ratio. The product is delivered without an encoder and the gear is not compatible with encoder add-ons in this version.

BMN04-0829 with SPG04 planetary gear is an excellent choice for applications in medical technology, precision instruments, miniaturized robotics and other areas where compactness, reliability and high torque are crucial.
