Product Description

The AM8022-0E21-0000 is a high-speed servomotor developed under Beckhoff’s esteemed product line, the AM8 servo motor series. Boasting a standstill torque of 0.8 Nm and a standstill current of 2.44 A, the AM8022-0E21-0000 demonstrates competitive driving capabilities for small and highly precise systems. When allowed to operate at optimal conditions, the AM8022-0E21-0000 can safely reach a ceiling mechanical speed of 12,000 rpm. Depending on the mains voltage, the machine’s output capabilities may vary. In general, for higher values of the supply voltage, the motor’s working speed tends to increase along with the shaft power, while the torque decreases.

At 115 V mains voltage, the AM8022-0E21-0000 exhibits the following nominal characteristics: 4000 rev/m, 0.76 Nm, and 0.32 kW. When the supply voltage is doubled, the machine’s working speed increases to 8000 rpm and the power to 0.59 kW. At this voltage level, however, the machine’s output torque decreases to 0.7 Nm. At the maximum possible supply voltage of 480 V, the AM8022-0E21-0000 achieves a nominal working speed of 9000 rpm and delivers 0.61 kW and 0.65 Nm. Based on the motor’s datasheet, the AM8022-0E21-0000 has a phase-to-phase winding resistance of 5.10 ohms at 20 degrees Celsius.

The AM8022-0E21-0000 features Beckhoff’s original iTec connection technology, along with a high-performing multi-turn motor feedback system. Unlike standard motor encoders, however, the AM8022-0E21-0000’s feedback system employs one-cable technology, which simplifies wiring and control system setup. Aside from the mentioned features, the AM8022-0E21-0000 also incorporates a standard 24 V holding brake, which requires 24 VDC supply and facilitates holding action at a permissible torque of 2 Nm. During operation, the holding brake takes 25 ms to fully release its actuators and 8 ms to initiate application.
