Gear motors

Bühler Motor supplies DC and BLDC motors with spur, planetary and worm gears that offer excellent value for money.
They are available as standard products, variants or customized options.

Planetary gears

Our plastic planetary drives are characterized by superb durability and quiet running at high torques.
In addition, they are both adaptable and economical.

Spur gears

Our spur gears are extremely robust, adaptable and economical.
They are used in any situation where a high reduction ratio in a small installation space is required.

Worm gears

Our worm gears (also: worm wheel gear) are used when the installation space requires a drive shaft bent by 90°.
Their technical advantages are high efficiency, quiet running and overload capability.
They can be combined with DC and BLDC motors in different performance categories.

bMotion – Modular Mechatronic Drive Solutions 

bMotion is a completely innovative modular drive platform of DC motors, gear boxes, brakes and encoders. Maximum modularity, easy combinability and a large number of predefined variants create drive solutions that are optimally tailored to customer needs.

Based on the platform‘s variety, the drive systems can be combined from already existing elements according to customer requirements. Thereby customer-specific developments can largely be replaced by configure-to-order. The expedited development does not mean a sacrifice in quality.
