Product Description:
As a permanent magnet-excited three-phase synchronous motor, the AM8053-0GH1-0000 servo motor is from Beckhoff and part of the AM series of synchronous servo drives. In this configuration, a stator-driven rotating magnetic field generated by three-phase AC excitation is magnetically coupled to permanent magnets embedded in the rotor. With zero slip in steady state, the highly synchronized torque response is achieved by the magnetic contact between the stator and rotor. Due to the synchronous operation and low rotor losses, this design provides a higher torque-to-inertia ratio, better dynamic response and higher electromechanical efficiency. This motor is suitable for automation applications that require minimum mechanical backlash, fast acceleration-deceleration cycles and high-resolution position feedback because of these combined features.
The 11.4 Nm standstill torque is the basis of the motor’s static performance and is crucial for keeping the angular position when the speed is zero. The maximum static torque to withstand external disturbances when the motor is not rotating is called the “standstill torque”. When mechanical holding force has to be maintained without using electromechanical brakes, like in position-critical systems or vertically mounted axes, this is particularly important. High standstill torque indicates a strong magnetic field density and well-optimized winding shape, which allows for steady electromagnetic clamping forces. By ensuring the motor can counterbalance resistive loads or external torques with minimal position drift, these features improve system reliability and reduce the need for auxiliary restraint devices in load-sensitive applications.
The thermal regulation of the AM8053-0GH1-0000 is done by passive convection cooling, a non-mechanical method that relies solely on the natural buoyancy-driven airflow around the motor’s outer surface. During operation, the heat generated in the stator windings and core is dissipated through the motor housing and into the surrounding air by surface-area-enhanced radiation and thermal conduction. In sterile or contaminant-sensitive industrial environments, the absence of active cooling components like fans or liquid-based circuits reduces acoustic emissions, eliminates moving parts that can break, and is especially beneficial. However, environmental factors like heat gradients, space constraints and ambient airflow will affect the efficiency of convection cooling. The motor’s working envelope, which is 5 to 40°C, shows the boundary conditions under which the motor can maintain thermal equilibrium without exceeding material thermal limits. This ensures operational life and integrity of the insulation and magnetic materials under continuous load.
Frequently Asked Questions about AM8053-0GH1-0000:
Q: What type of motor is the AM8053-0GH1-0000?
A: It is a permanent magnet-excited three-phase synchronous motor. This means it uses permanent magnets on the rotor and requires a three-phase AC power supply for operation, which allows for precise control and high efficiency in industrial applications.
Q: What is the standstill torque of this motor?
A: The motor delivers a standstill torque of 11.4 Nm. Standstill torque is critical in applications where holding force is needed without movement, such as in positioning systems or when loads need to be held in place.
Q: What kind of cooling does it use?
A: It uses convection cooling. This means the motor is designed to dissipate heat passively through its surface without the need for additional fans or liquid cooling, making it suitable for clean and quiet environments.
Q: What is the rated speed and what does it mean?
A: The rated speed is 2000 min⁻¹ (or RPM), which represents the speed at which the motor operates most efficiently under load. This speed allows the motor to maintain high performance in automation systems requiring precise motion control.
Q: What is the motor’s peak torque?
A: The peak torque is 53.1 Nm. This is the maximum torque the motor can deliver for short periods, allowing it to handle dynamic loads and quick acceleration without damage, especially during startup or when resisting sudden mechanical forces.
