Motion Control — Drives: The 3890 CR coreless dc motor ensures cogging-free, precise synchronization with very low energy consumption. This is a Control Engineering 2015 Engineers’ Choice finalist. Courtesy: Faulhaber, MicromoMicromo is pleased to announce the latest addition to the Faulhaber CR dc motor series. Its graphite commutation, powerful neodymium magnet and particularly high copper content in the Faulhaber rotor winding provide the compact 3890 CR with an enormous amount of power.

For drives in applications such as autonomous robot system and electro-mechanical orthotic systems and exoskeletons, 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 synchronization with very low energy consumption. The 3890 CR series offers everything required for use in challenging power applications.

The new 3890 CR dc motor series is available as standard with four nominal voltages: 18, 24, 36, and 48 V. A continuous torque of up to 224 mNm is also part of the performance package. 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 for combination with Faulhaber 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.
