Product Description:
The AM8111-0F00-0000 Servo Motor is developed by Beckhoff. It is a servo module that can hold small torques at standstill, burst higher torques briefly and is relatively energy efficient.
The AM8111-0F00-0000 servo motor bearings are designed to last at least 30,000 hours of operation under rated conditions, ensuring reliability and long service intervals. It can momentarily produce 0.68 Newton-meters which is useful for quick bursts of power during acceleration or sudden load changes. If it is used above 1000 meters elevation or at temperatures over 40°C, its performance such as current and torque must be reduced to prevent overheating or damage. It draws 2.85 A RMS current to maintain its standstill torque when it is holding position without rotation. The inductance is 1.5 millihenries between the motor phases. For every RPM of shaft speed 5 millivolts RMS are generated between phases. Every ampere of RMS current produces 0.07 Nm of torque which indicates its electrical to mechanical torque conversion efficiency. It is built specifically for operation at a maximum nominal supply voltage of 50 VAC.
The AM Synchronous Servo Motors series module has a resistance of 2.30 ohm at 20°C. It comes in the climatic category of 3K3 according to EN 60721 which suggests it is intended for indoor industrial uses and occasional condensation but not severe weather exposure. It is well suitable for humid environments but not direct exposure to water. It has a 10000 revolutions per minute maximum safe shaft speed which is quite high which means it can handle fast rotations. It is rated for environments between +5°C and +40°C at altitudes up to 1000 meters above sea level.
Frequently Asked Questions about AM8111-0F00-0000:
Q: How does the torque constant of 0.07 Nm/A impact motor control precision?
A: The torque constant helps in achieving predictable torque output per ampere of current. This ensures stable and accurate servo control in dynamic applications.
Q: Why is the 8.6 A peak current capacity important for the AM8111-0F00-0000 servo motor?
A: The peak current enables the motor to handle sudden load spikes or acceleration needs. It enhances responsiveness without compromising motor safety.
Q: What role does the 1.5 mH winding inductance play in servo performance?
A: Inductance helps reduce current ripple and improves signal filtering. It ensures smoother current transitions for more efficient operation.
Q: How does 2.30 Ω winding resistance influence power loss in AM8111-0F00-0000?
A: Higher resistance slightly increases power loss in the form of heat. It also affects thermal management and efficiency at high loads.
Q: What happens if the AM8111-0F00-0000 operates at voltages higher than 50 VAC?
A: Operating beyond rated voltage risks insulation damage and reduced service life. The servo system may also face instability or overcurrent faults.
