AM8122-1FH0-0000

Product Description:

Beckhoff manufactures the AM8122-1FH0-0000. Three-phase, permanent magnet-excited power drives the Beckhoff AM8122-1FH0-0000 synchronous servo motor. Permanent magnets built within the rotor by this design constantly interact with a revolving electromagnetic field produced by the stator windings. A very linear torque output with precise positional precision is the end result. Even under dynamic circumstances, three-phase excitation promotes steady motion by minimizing torque ripple and ensuring smoother torque production throughout the whole electrical revolution. By maintaining a steady magnetic field without the energy losses usually associated with field excitation windings, permanent magnets provide an inherent design benefit that enhances thermal stability and energy economy throughout extended industrial operations.

The motor's 0.80 Nm standstill torque is crucial in applications that need a strong holding position before motion starts and in situations with static loads. Even when there is no rotational movement, the static torque performance results from the continuous interaction between the rotor's fixed magnetic field and the stationary stator field, a motor with inadequate static torque would be at danger of positional drift or mechanical slippage under high-friction or load-holding conditions, especially in systems that are vertically oriented or need high accuracy. Additionally, the motor's peak current capacity of 22.4 A shows that it can withstand brief spikes in electrical demand, which are required for sudden load changes or fast acceleration. The system can remain responsive without experiencing heat overload or mechanical fatigue because of its ability to withstand brief electrical stressors.

Under nominal voltage settings, the AM8122-1FH0-0000 reliably balances torque output and rotational velocity while operating at a rated speed of 2000 min⁻¹. Convection cooling provides effective thermal control by enabling passive air movement to remove heat produced inside by resistive and core losses. This thermodynamic characteristic generates a self-sustaining cooling loop without the need for auxiliary equipment by relying on density variations in the surrounding air layers. With a precise value of 0.253 kgcm2, the rotor's moment of inertia allows for quick changes in angular velocity while using little energy. Because they improve system bandwidth and decrease dynamic lag, low inertia values are especially useful in control systems that need frequent acceleration-deceleration cycles. This allows for precise control over motor placement and motion trajectories in high-speed automation settings.
