Product Description

The AM8122-0F20-0000 is an advanced servo motor manufactured by Beckhoff. This motor's "permanent magnet-excited" nature ensures a high power density and efficiency, as the rotor's magnetic field is inherently present and does not need to be induced by an external current. Its Nominal Voltage (24…48 V DC) specifies the direct current voltage range at which the motor is designed to operate optimally. The Standstill Torque equals 0.80 Nm, and the Rated Torque is 0.80 Nm. Torque is the rotational force the motor can exert. The standstill torque represents the maximum torque the engine can produce from a stationary position, which is crucial for applications requiring high initial acceleration. The Peak Torque of this servo motor is 4.06 Nm. This signifies the maximum instantaneous torque the motor can generate for brief durations, often required for overcoming transient loads or achieving rapid acceleration bursts.

The Rated Speed of this device is 2000 min⁻¹. This is the rotational speed at which the motor continuously delivers its rated power and torque. It influences the mechanical output speed and the system's overall performance. Its Rated Power is 0.17 kW, which indicates the electrical power the motor consumes to deliver its rated torque and acceleration. It directly impacts the motor's size, cooling requirements, and efficiency. The Standstill Current is 4.0 A, and the Peak Current is 22.4 A. The standstill current is drawn when the motor is at rest but energized, and the peak current is the maximum allowable instantaneous current. These parameters are critical for sizing the motor's power supply and protection circuits.

The Torque Constant of this module is 0.20 Nm/A. This fundamental parameter defines the relationship between the motor's torque output and the current flowing through its windings. A higher torque constant implies a greater torque output for a given current, improving responsiveness and controllability. The Rotor Moment of Inertia of the AM8122-0F20-0000 is 0.253 kgcm². This represents the rotor's resistance to changes in its rotational motion. A lower moment of inertia allows for faster acceleration and deceleration, enhancing the motor's dynamic performance. The Motor Feedback (resolver, single-turn absolute encoder, OCT, EnDat 3, 19-bit, SIL 3-capable) refers to the sensors integrated into the motor to provide precise information about its position, speed, and potentially other parameters.
