The AKM21C-CKMN2-00 is from the AKM brushless DC motor series and gives a great performance in areas where precise speed, position and torque control is required. The motor has a rated speed, rated torque and rated power of 2500 rpm, 0.46 Nm, and 0.12 kW respectively at At UN = 115 V. When UN = 230 V, these values are 8000 rpm, 0.39 Nm, and 0.32 kW. For the closed-loop feedback, the AKM21C-CKMN2-00 uses the Comcoder with 2048 PPR. The encoder is operated with the SERVOSTARservoamplifier and together these components provide real-time control over the motor speed, torque, and position. At a peak current of 6.3 A, the motor has a peak torque of 1.47 Nm. A 0.48 Nm standstill torque can be applied to the output shaft at a standstill current of 1.58 A.
The motor comes with the international protection standard IP 65. This standard ensures protection against dust particles and low-pressure water jets from all directions. The rotor’s moment of inertia is 0.11 kgcm2 and the and motor shaft comes with an open keyway. With a 0.82 kg weight, the motor can give smooth performance in a 5 ᵒC to 40 ᵒC temperature range. Without a doubt, the AKM21C-CKMN2-00 comes as a reliable and affordable platform and is the ideal candidate for modern servo requirements.
