Product Description:
The AKM21E-EFM2R-00 is a robust and versatile servomotor launched by Kollmorgen. The motor features plug-and-play motor recognition and full-frequency autotuning on AKD series servo drives. The device must never be sprayed with or immersed in liquid for cleaning. The product has a matt black enamel finish. The unit features a brushless design and is a great choice for positioning tasks when combined with a digital servo amplifier from the same manufacturer. A spring applied brake of 24V DC is integrated into the AKM servomotor. When the hold 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 motor has a resolver feedback unit incorporated into it. The unit has a rotor moment of inertia of 0.11 J. It has a total of 6 poles. The radial load permitted at the shaft end of the servomotor 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 without a low-resistance earth connection, electrical safety is not possible. Even when the servomotor is not rotating, power connections may be live. The power connections of the motor should never be disconnected when the equipment is being energized. The device should not be opened for cleaning or other purposes. Opening the servomotor voids the warranty.
Frequently Asked Questions about AKM21E-EFM2R-00:
Q: When should the ball bearings of the AKM servomotor be replaced?
A: The ball bearings of the AKM servomotor should be replaced when bearing noise is heard. The user should check the motor for bearing noise every 2500 operating hours.
Q: What kind of magnets are present in the rotor of the AKM servomotor?
A: The rotor of the AKM servomotor is embedded with permanent magnets that comprise rare earth neodymium-iron-boron magnetic materials.
Q: What are the mounting orientations supported by the AKM servomotor?
A: The AKM servomotor supports horizontal and vertical mounting orientations. The motor does not support diagonal orientation.
Q: Who can assemble the AKM servomotor?
A: Only qualified staff with expertise in mechanical engineering should assemble the AKM servomotor.
Q: Under what conditions can the user operate the AKM servomotor?
A: The user should operate the AKM servomotor only under the ambient conditions defined in the product manual.
