Evidence boundary

Radwell identifies MDFKAIG100-22 as a Lenze servo motor rated at 13.2 kW, 3510 RPM, and 36 Nm.

Alfa identifies the exact reference as a three-phase, forced-ventilated asynchronous servo motor with an incremental encoder and frame size 100.

System inference: At system level, this unit is the rotary actuator between the servo drive and the machine axis. This placement is an inference from the cited facts.

Unknown: installation fit, feedback wiring, and commissioning limits require separate evidence.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Converts controlled electrical input into rotary shaft motion as a servo motor.
System position: Sits downstream of a servo drive and upstream of the machine axis.
Upstream / inputs: Receives controlled electrical power and motion commands from the servo drive.
Downstream / outputs: Delivers rotary shaft torque to the driven machine.
Limitations: Unknown: installation fit, feedback wiring, and commissioning limits require separate evidence.
