Faulhaber Evolves Precision Drive Systems with Innovative Magnetic Design and Winding
Technology
With an integrated design approach that incorporates innovative magnetic designs and winding technology, Faulhaber has
expanded its range of compact yet powerful motor and drive
systems for precision products and devices used in robotics,
laboratory automation and medical markets.
gearheads and controls, the result is a compact drive system.
Faulhaber advocates a complete systems approach in its product
development. Electric motors are not typically "lone wolves" but
for most applications need to be combined with gearheads for
speed reduction as well as encoders, explains the company.
By adding corresponding gearheads, integrated encoders, and
speed controllers that are exceptionally short in the axial direction, it has extended the BXT flat motor series in a manner that
all components are perfectly matched to each other.
BXT brushless flat motor with external rotor design
Shown above is the company's brushless flat BXT motor with
external rotor technology. The external rotor motors of its BXT
series set new standards, says the company. Employing innovative winding technology and optimized design, the motors deliver
a torque of up to 134 mNm. The ratio of torque to weight and size
is unmatched, says Faulhaber.
The iron-core motors have 14 high-performance rare earth magnets on the rotor and 12 teeth on the stator yet measure just 14
mm, 16 mm and 21 mm long. They were developed based on the
classic external rotor design, employing special winding technology to generate more torque. Due to the high copper filling factor
and the design of the pole shoes, the magnetic field is strong and
the cogging torque very small. The motors can operate at speeds
up to 10,000 rpm. Combined with optical and magnetic encoders,

Three sizes in the BXT motors family
The three sizes can solve many different drive challenges. In the
case of a lower-arm prosthesis, for example, the smallest drive
with a diameter of 22 mm would be ideal for the hand and the
16 mm long motor for the elbow. Other possible applications for
the small compact drive systems are robot grippers, industrial automation, humanoid robots, even bio-robotics for motorized hand
exoskeletons as well as dialysis machines and medical pumps.
