With the introduction of the BX4 series of brushless DC
servomotors, FAULHABER once again underscores
its position as an innovative market leader in highly
integrated miniature drive systems. Using the latest production methods, some specially developed by FAULHABER, the company has come up with a modular
design that is limited to just a few components and entirely eliminates the need for adhesive-bonded joints.

Despite the compact dimensions, the new four-pole concept of the series ensures a high continuous torque of up to 12.2 mNm, with a flat gradient of the n/M characteristic curve.

Notable features are the smooth running characteristics and the particularly low noise level. Thanks to its electronic commutation, the brushless servo motor series is characterised by a much longer service life than mechanically commutated drives. Whilst in the basic version the commutation is provided by an external control, the flexible motor concept of the BX4 series also offers versions with integrated speed controller or integrated encoder. The encoder version is available in four different preset resolutions: 32, 64, 128, or 256 quadrature impulses per
revolution. It is available with an optional line driver and differential output signal.

In addition to mechanical speed adjustment, the new planetary gearheads of the 22F series also allow a temporary torque increase up to 1500 mNm. Designed with one to four stages, the precision gearhead in steel offers 21 finely graduated reduction ratios, and the diameters can be
combined in conformity with the BX4 drives.
