Product Description

The AKM21G-ENGN2-00 is one of the top productions of Kollmorgen, it is a sophisticated industrial motor designed to function as a reliable and accurate source of kinetic energy in industrial production and processing applications. This industrial motor is designed to be used with the AKD drive controller series, the combination of this motor with the Intelligent AKD controller forms a rapid response system that maintains a higher efficiency, and flexible operation. The AKM21G-ENGN2-00 industrial motor is a brushless device, during operation the motor generates a low amount of noise, also delivers a shaft power that is about 47 percent higher than conventional industrial motor designs. The handling of this sophisticated motor is fairly easy, however this handling should still be done by an industrial professional that is familiar with Kollmorgen devices and have gone through the documentation delivered with the motor. The AKM21G-ENGN2-00 industrial motor can be configured through the use of the efficient plug-and-play motor recognition commissioning technique. The housing of his industrial motor is designed to resist most external interference, the housing is also covered with a black coating which protects the motor from rapid deterioration by preventing a direct contact between the motor and corrosive liquid substances such as dilute acids, dilute alkali, mineral oil and sea water. The AKM21G-ENGN2-00 is designed in a way that allows for the easy dissipation of heat via natural convection, motor design also ensures exceptional low cogging. The AKM21G-ENGN2-00 industrial motor requires a continuous input current of 4.87 Amperes during operation, it also generates a continuous torque of 0.50 newton meters at standstill. At a maximum input current of 19.5 amperes, this industrial motor can generate a maximum torque of 1.51 newton meters.

Frequently Asked Questions about AKM21G-ENGN2-00


Q: What does the classification of the AKM21G-ENGN2-00 into the 3K3 climatic category mean?

A: This classification means the the AKM21G-ENGN2-00 motor is suitable for use in temperature controlled locations without humidity regulation. Heating and cooling might be necessary to maintaint the necessary ambinet conditions around the motor.

Q: What type of protection does the PTC termistor integrated into the winding of the AKM21G-ENGN2-00 motor provide?

A: The PTC termistor integrated into the winding of the AKM21G-ENGN2-00 motor monitors the winding temperature and protects the motor from overload damage. This thermistor however doe not provide protection against short, and heavy overloading.

Q: Is the AKM21G-ENGN2-00 motor resistant to vibration?

A: Although the robust design of the AKM21G-ENGN2-00 motor offers some degree of protection against mild vibrations, it offers no protection against heavy vibrations. The motor should be protected against extreme vibrations.

Q: Is the AKM21G-ENGN2-00 motor delivered with the electrical cables it required for power and feedback connections?

A: No. Kollmorgen produces ready made power and motor feedback cables. Customers are expeceted to make separate request for these electrical cables.

Q: How does installation height affect the operation of the AKM21G-ENGN2-00 motor?

A: When the AKM21G-ENGN2-00 motor is installed at a height that exceeds 1000 meters a reduction in rated data of the motor should be expected. The higher the installation height the higher the reduction in rated data.
