FAULHABER BXT Today, you don't find visionary designs in Hollywood, but rather in the development departments of innovative companies. Requirements for drives are changing – particularly when high-torque motors are required that are as short as possible in the axial direction due to limited installation space, it is often difficult to find a suitable solution. With the innovative BXT motor family, FAULHABER extends the limits of what is possible for such requirements.

More power in a very small space From robotics to prosthetics and even in the medical and laboratory technology: this requirement arises frequently. In terms of making compact yet still extremely high-torque motors, the design of the motor winding and its production are critical. This is where FAULHABER comes in, who has developed the new FAULHABER BXT motor family on the basis of traditional external-rotor motors. As the motors are only 14 mm, 16 mm and 21 mm short in the axial direction, they are easy to accommodate in applications that offer little space. The three sizes can solve many...

Brushless flat motors with External rotor technology The external rotor motors of the BXT series set new standards: thanks to innovative winding technology and optimum design, the BXT motors deliver a torque of up to 134 mNm. The ratio of torque to weight and size is unmatched. The iron-core motors with 14 high-performance rare earth magnets on the rotor and 12 teeth on the stator are just 14 mm, 16 mm and 21 mm long, making them suitable for applications that require a short drive solution with high torque. Combined with optical and magnetic encoders, gearheads and controls, the result is a...

FAULHABER BXT Advantages of this series at a glance External rotor motors with very high torque Flat design for space-critical applications. Length range of 14 to 21 mm. Matching optical and magnetic encoders, gearheads and controls available Outstanding ratio of torque to weight and size Angaben zu Lebensdauer sowie weitere technische Erläuterungen siehe „Technische Informationen“.

Brushless Flat DC-Servomotors Technical Information FAULHABER BXT Housing (for BXT H) Rotor with shaft and ball bearing Front flange with ball bearing General Information The FAULHABER BXT motors are ideally suited for applications with low to medium speed that require a high torque in short design, high efficiency and long service life. With the unhoused BXT R motors, the rotor turns freely. The BXT R motors may only be operated in a suitable environment. Dirt and humidity could penetrate the motor and reduce the service life. If hair or clothing become caught in the rotor, there is a risk...

Rotor inertia J [gcm2] The moment of inertia of the rotor. Unspecified mechanical tolerances: Tolerances in accordance with ISO 2768. ≤ Angular acceleration αmax. [rad/s2] The acceleration obtained from standstill under no-load conditions and at nominal voltage. The tolerances of non-specified values are available on request. All mechanical dimensions related to the motor shaft are measured with an axial preload of the shaft toward the motor. Operating temperature range [°C] Indicates the minimum and maximum standard motor operating temperature, as well as the maximum allowable temperature of...

Brushless Flat DC-Servomotors Technical Information Nominal slope of the n/M characteristic curve [min-1/mNm] An approximation of the current slope at the specified rated values. This value is derived from the torque and speed values when idling with respect to the rated values. Explanations on the performance diagram The performance diagrams show the range of possible measured operating points of a drive at an ambient temperature of 22°C and include both the operation on the plastic as well as aluminium flange. The possible speed ranges are shown in dependence on the shaft torque. The sector...
