Product Description

The AM8022-0D21-0000 is one of Beckhoff’s top-selling products, manufactured under the AM servo motor family line. The AM8022-0D21-0000 particularly excels for highly accurate applications, requiring the rotor to be stationary at precise periods and durations. This three-phase synchronous motor employs Beckhoff’s latest one-cable technology, allowing the rotor’s position to be accurately determined, along with the number of completed revolutions. For applications requiring the rotor to be stationary at precise instants, the AM8022-0D21-0000 employs a suitable blocking brake that does the job well. The holding brake can hold the rotor in place at a maximum torque of 2 Nm at the highest permissible winding temperature of 120 degrees Celsius.

During operation, the AM8022-0D21-0000 tolerates an ambient temperature of 5 to 40 degrees Celsius. Whenever transporting the AM8022-0D21-0000, however, the applicable ambient temperature range is between -25 and 70 degrees Celsius. For storage purposes, the recommended temperature range is -25 to 55 degrees Celsius. For both storage and transport, however, the motor must not be subjected to adverse temperature changes or fluctuations. At most, the machine can tolerate 20 Kelvin or Celsius of temperature drop or rise, provided the steady-state temperature falls within the applicable thermal range. To facilitate cooling, the AM8022-0D21-0000 employs air convection since it does not come with any surface-mounted fans.

During locked-rotor conditions, the AM8022-0D21-0000 achieves the following standstill values: 0.8 Nm and 1.5 A. At most, however, the machine may safely draw a peak current of 7.7 amperes and transmit a maximum torque of 4.18 Nm. For every one ampere increase at its input side, the corresponding torque increase on its output side is 0.53 Nm. The increase in the machine’s output torque is approximated using the AM8022-0D21-0000’s torque constant, which is 0.53 Nm/A. At a terminal supply voltage of 400 V, the AM8022-0D21-0000 has a nominal operating speed of 8000 rpm.
