Product Description

The AKM21E-BNBN1-00 is a robust brushless servomotor from the house of Kollmorgen. The motor incorporates rotatable angular connectors and a comcoder with 1024 PPR feedback system. The motor features a smooth shaft, and its winding type is E. The flange size of the product is 58 mm, and its flange is customized to NEMA Standard. The device is coated in a matt black finish. The device has a thermal contact in its windings. The motor should not be directly connected to the mains supply. The motor connection should be done using only the cables and accessories supplied by Kollmorgen. The AKM servomotor has a maximum bus voltage rating of 640 VDC. The standstill torque of the unit is 0.50 Nm and its standstill current is 3.11 A. The product has a maximum mains voltage of 480 VAC. The peak current of the motor is 12.4 A and the peak torque is 1.49 Nm. The static friction torque of the device is 0.002 Nm. The thermal time constant is 8 minutes. The device is not equipped with a holding brake. Retrofitting of the brake is not possible. The AKM servomotor should be protected from unacceptable stresses. Care should be exercised, especially during transport and handling that components are not bent and that insulation clearances remain unaltered. The site should be free of aggressive and conductive material. In the case of V3-mounting (shaft end upwards), no liquids should enter the bearings. If an encapsulated assembly is needed, the applications department of Kollmorgen should be consulted beforehand. The motor needs unhindered ventilation. The permissible ambient and flange temperatures should be observed. For ambient temperatures above 40?C, the applications department of the manufacturer should be consulted well in advance.
