Product Description:

The AKM21G-BSMN1-02 is a brushless DC servomotor launched by Kollmorgen. The motor should be operated only under the ambient conditions defined in the product documentation. The device is intended for drives with high requirements for dynamics and stability. The product is installed as a component in machines or electrical apparatus and can only be commissioned and operated as an integral element of such machines or apparatus. The unit has a thermal sensor integrated into its windings, which should be observed and evaluated. The AKM servomotor is not equipped with an in-built brake. Retrofitting of the brake is not possible. The motor is coated in matt black with a polyester powder coating. The finish is not resistant to solvents like nitro-thinners and trichloroethylene. The device has a 0.5m shielded cable with IP20 connectors for power supply and feedback signals. The unit features a comcoder with 1024 PPR feedback unit. The servomotor has a standstill torque of 0.50 Nm and a standstill current of 4.87 A. The maximum mains voltage of the device is 480 VAC. The motor features a special shaft. The site of installation of the AKM servomotor should be free from conductive and aggressive material. In the case of IM V3 mounting, care should be taken that no liquids enter the bearings of the motor. If an encapsulated assembly is needed, it is important to consult the applications department of Kollmorgen beforehand. Care should be taken to ensure that the motor has unhindered ventilation. The permissible ambient and flange temperatures should be maintained. Adequate heat transfer in the servomotor flange and the surroundings should be ensured. During wiring and assembly, the user must make sure that the device is de-energized.
