Product Description

The Kollmorgen AKM21G-BSMN2-03 synchronous servomotor is designed to offer superior class performance coupled with industry-leading power density. The device is easy to commission and use with full-frequency autotuning and plug-and-play motor recognition. The weight of the motor is 0.82 kg. The unit does not have brushes; commutation is performed electronically by the servo amplifier used. The device should be operated only under the ambient conditions defined in the product documentation. The AKM servomotor comes with a flange size of 58 mm and a rotor length of 1. It features winding type G and is incorporated with a 0.5m shielded cable with IP20 connectors. The device is equipped with a comcoder with 1024 PPR feedback unit. Care should be taken that the motor is connected directly to the mains supply. The thermal contact integrated into the windings of the servomotor must be observed and evaluated. The standstill torque of the device is 0.50 Nm and its standstill current is 4.87 A. The maximum mains voltage of the unit is 480 VAC. The AKM servomotor is equipped with ball bearings, which should be replaced after 20,000 hours of operation under rated conditions. The motor must be checked for bearing noise once every 2,500 operating hours. In the case of noises, the operation of the motor must be stopped, and the bearings should be replaced. Wherever possible, only backlash-free, frictionally locking couplings or collets should be used. The couplings must be correctly aligned. A displacement will lead to unacceptable vibration, and the bearings and the coupling will be destroyed or damaged. The device should not be opened by the user for cleaning or other purposes because opening the device invalidates the warranty.
