Product Description:

The AKM53K-ACCNEF-00 synchronous servo motor is from the AKM series of motors, which is designed to provide precise motion control by synchronizing the rotor speed with the frequency of the supplied current. This guarantees precise control of speed and position, which is very important in situations where performance must be consistent and reliable.

The AKM53K-ACCNEF-00 servo motor is equipped with a motor constant of 0.973 Nm/√W, a back EMF constant of 63.6 Vrms/krpm, and a torque constant of 1.24 Nm/Arms. Within the lines, there is 0.69 ohms of resistance and 3.64 mH of inductance. The inertia is 8.1E-03 lb-in-s² with the resolver input, and it goes up to 0.166 kg-cm² with the optional brake. A servo motor that does not have a brake weighs 7.4 kg. At 0.058 Nm, static friction is measured, and at 0.052 Nm/krpm, viscous suspension is recorded. It takes 28 minutes for heat to travel, and there is 0.50 °C of resistance for every W generated. The motor works in temperatures from -20°C to 40°C and has five sets of poles. The heat absorber that most people suggest is a metal plate that is 12" x 12" x 1/2". There are brakes on the servo motor and different ways to arrange the shafts. The servo motor has been approved by both CE and UL, and it can be easily set up with Kollmorgen devices.

The AKM53K-ACCNEF-00 servo motor may be easily integrated with Kollmorgen servo actuators and is compatible with a variety of feedback devices. The motor is constructed from materials that are renowned for their outstanding thermal endurance, and it has a permanently magnetized rotor. To ensure continuous functioning, the design minimizes harmonic distortion and cogging. Due to its modular design and minimal static friction, it can be easily adjusted to meet the needs of different installations, ensuring accurate low-speed performance.

Frequently Asked Questions about AKM53K-ACCNEF-00:

Q: Why does AKM53K-ACCNEF-00 have a 28-minute thermal time constant?

A: The 28-minute thermal time constant allows the motor to dissipate heat gradually. This prevents overheating during continuous operation.

Q: Does AKM53K-ACCNEF-00’s 0.69-ohm resistance affect performance?

A: Yes, the 0.69-ohm resistance controls current flow and heat generation. It impacts efficiency and thermal management.

Q: How does the 3.64 mH inductance benefit AKM53K-ACCNEF-00?

A: The 3.64 mH inductance smooths current changes. This reduces electrical noise and improves motor response.

Q: Why is the motor constant of 0.973 Nm/√W important for AKM53K-ACCNEF-00?

A: The motor constant indicates torque output per power input. It helps evaluate motor efficiency and energy usage.

Q: Does AKM53K-ACCNEF-00’s static friction of 0.058 Nm impact startup?

A: Yes, low static friction reduces resistance at startup. This improves low-speed control and responsiveness.
