The development of the new 3890...CR series is based on the motor concept of the CR DC-Micromotors series with Graphite Commutation from FAULHABER. A powerful neodymium magnet and particularly high copper content in the winding of its rotor provide the compact drive with a high 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 a small space are central requirements. In addition to the power density (rated torque per volume), the high efficiency of the micromotor is also a decisive factor. Thanks to the further development of the commutation system, the motor also achieves high service life values even with heavy loads. The coreless rotor also ensures cogging-free, precise synchronisation with very low energy consumption. The new 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.
