Product Description:
The Kollmorgen AKM21C-CKB2C-00 is a high-performing servomotor that is equipped with a Smart feedback device. The motor is easy to commission and use with plug-and-play motor recognition and full-frequency autotuning on an AKD servo drive. The product has an open keyway shaft. The device must never be sprayed with or immersed in liquid for cleaning. The product sports a matt black enamel finish. The motor features a brushless design and is a good choice for positioning tasks when combined with a digital servo amplifier. A spring applied brake of 24V DC is integrated into the AKM servomotor. When the holding brake is de-energized, it blocks the rotor. The holding brake is designed as a standstill brake and does not suit repeated operational braking. The holding brake can be directly controlled by a SERVOSTAR servo amplifier. If the brake is not directly controlled by the servo amplifier, additional wiring is required. The unit has a rotor moment of inertia of 0.11 J. The radial load permitted at the shaft end of the motor at 5000 per minute is 145 N. The holding torque of the brake of the device at 120?C is 1.42 Nm. The housing of the AKM servomotor must be safely earthed to the PE busbar in the switch cabinet. It should be noted that even when the motor is not rotating, power connections may be live. The power connections of the unit must never be disconnected when the equipment is being energized. The key must be removed from the shaft before allowing the device to run independently in order to avoid dangerous consequences of the key being expelled by centrifugal forces.
