FAULHABER 3890...CR series DC‐Micromotors

Click2Contact

The 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 high copper content in the winding of the rotor provide the compact drive with a large amount of power.

For drives in autonomous robot systems, electromechanical orthoses and exoskeletons or power tools like the electric loppers, high dynamics and torque in the smallest possible space are central requirements. The micromotor series features high power density (rated torque per volume), high efficiency and high service life, even with heavy loads. The coreless rotor ensures cog-free, precise synchronisation with low energy consumption.

The series is available with four nominal voltages — 18, 24, 36 and 48 V — enabling a continuous torque of up to 224 mNm to be achieved. The short-term torque, required for many applications, is much higher. With no-load speeds of just over 5000 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.
