DC‐Micromotors series 3890...CR

The development of the new 3890…CR series is based on the successful motor concept of the CR DC-Micromotors series with Graphite Commutation from FAULHABER. A very powerful neodymium magnet and particularly high copper content in the winding of its FAULHABER rotor provide the compact drive with an enormous amount of power.

For drives in autonomous robot systems, electro-mechanical orthoses and exoskeletons or power tools like the electric loppers, high dynamics and torque in the smallest possible space are central requirements. In addition to the one-of-a-kind power density (rated torque per volume), the high efficiency of the 3890…CR series is also a decisive factor. Thanks to the further development of the commutation system, the motor also achieves high service life values even with extremely heavy loads. The coreless rotor also ensures cogging-free, precise synchronisation with very low energy consumption. In short: the 3890…CR series offers everything required for use in challenging power applications.

The new 3890…CR DC-Motors series is available as standard with four nominal voltages: 18 V, 24 V, 36 V and 48 V. A continuous torque of up to 224 mNm is thereby achieved as well. The short-term torque, required for many applications, is much higher. With no-load speeds of just over 5,000 rpm, the motors are optimally tailored to combination with FAULHABER Precision Gearheads. The standard drive can be combined with an IE3-1024 (L) three-channel encoder or optionally with optical encoders from the HEDx series for applications with precise speed controllers or positioning tasks.
