Product Description:

The AKM42G-ANSNGF-02 Synchronous servo motor is a three-phase permanent magnet servomotor made by Kollmorgen. The AKM series offers a variety of frame diameters and stack lengths, enabling users to select the motors that are most suitable for their industrial automation requirements.

The AKM42G-ANSNGF-02 synchronous servo motor is made to work at 90 VDC and has a torque of 4 Nm all the time, with a high torque of 6 Nm. Because the motor is able to withstand a constant current of 4 A as well as a high current of 6 A, it is able to function dependably regardless of the load that is being applied to it. The standard speed of the servo motor is 3000 RPM, and the top speed can go up to 6000 RPM. The back EMF properties are set by the voltage constant of 25.1 V/krpm. The coil resistance of 2.51 Ohms at 25°C has an impact on the efficiency of heat utilization and the effectiveness of the device. This helps the insulation last longer. As a result of its fine control and little cogging, the synchronous servo motor is an excellent choice for applications that require accurate positioning.

The AKM42G-ANSNGF-02 servo motor can be used in situations where stable control of speed and power is needed. The insulation class is F, which means the coils may reach temperatures of up to 100°C above 40°C. This synchronous servo motor has an IP54 security grade, which indicates that it does not permit dust or water to flow through itself. The typical temperature of the surrounding environment is 40 degrees Celsius, which is nearly equal to the temperature that would be found in control enclosures.

Frequently Asked Questions about AKM42G-ANSNGF-02:

Q: Why does AKM42G-ANSNGF-02 use Class F insulation?

A: Class F insulation allows the winding temperature to rise up to 100°C above ambient. This extends motor life and supports continuous operation.

Q: Does AKM42G-ANSNGF-02 support high-speed applications?

A: The motor achieves a maximum speed of 6000 RPM. This enables its use in fast and dynamic motion control tasks.

Q: Why is 2.51 Ohms of resistance specified for AKM42G-ANSNGF-02?

A: The 2.51 Ohms resistance at 25°C helps manage thermal dissipation. It also impacts the efficiency and current draw of the motor.

Q: How does AKM42G-ANSNGF-02 handle peak loads?

A: The motor supports a peak torque of 6 Nm and a peak current of 6 A. This allows short bursts of high load without damage.

Q: Why is IP54 protection important for AKM42G-ANSNGF-02?

A: IP54 protection ensures resistance against dust and water spray. This maintains motor reliability in typical control cabinet conditions.
