Product Description

AM3073-0Q21-0000 is a synchronous motor. It is part of the AM3000 servo motor series from Beckhoff. The motor supports feedback via a multi turn encoder with EnDat interface. EnDat is a digital communication interface specifically designed for absolute encoders. It provides a means for transmitting position and status information between the encoder and a control system, such as the servo drive required to control and manage AM3000 Beckhoff motors. The AM3073-0Q21-0000 motor has a 188 millimeter flange for mounting. Supported mounting positions are IM B5, IM V1, and IM V3. The motor shaft can rotate at speeds of up to 6000 RPM. Beckhoff has designed the unit to accept maximum 480 Volts mains input. It can also operate at 400 Volts AC. Performance ratings for 480 Volts include 3500 RPM, 22 Nm and 7.71 kilowatts.

Performance ratings for 400 Volts include 3000 RPM, 25.2 Nm and 7.92 kilowatts. Peak output torque and current values for the AM3073-0Q21-0000 motor are 168 Nm and 122.6 Amps. Torque constant for the servo motor is 1.69 Nm/A. Voltage constant for the motor is 109.2 mVmin. Specifications for the motor winding include 0.24 Ohms resistance and 3.8 millihenry inductance. Moment of inertia of the rotor on the servo motor is 92 kg cm2. Rating for static friction torque is 0.24 Nm. Weight of the motor is 26.7 kilograms approximately. The permitted axial force is 500 N and the permitted radial force is 1300 N. A holding brake on the motor provides added operational safety. It requires 24 Volts DC to release the motor shaft. During operation the brake draws 1.48 Amps. Typical backlash of the brake is 0.2.
