- compact axial length, optimal torque/weight ratio possible in    a high performance dc servo motor - with NdFeB magnet material - 0,13... 3,2 Nm (43... 1.000 W) - nominal speed up to 5.000 rpm - for high-dynamic applications and/or exact regulations at    large speed range - zero cogging for smooth operation, even at crawling speed - available with integrated tacho (marked with asterisk * in    charts below), optical encoder, second shaft end, failsafe brake and precision    gearhead

The KN-series ServoDisk motors makes use of the flat disc armature and high-energy neodymium-iron-boron magnets resulting in an ultra-thin motor. The ironless, low intertia armature delivers high acceleration and zero cogging.

The rated data of our motors generally refer to 3000 rpm. Therefore the rated voltage are uneven. Of course our motors can operate at standard dc battery voltages of 12, 24 or 48 V. Please click here for the modified values.
