Product Description

AM8031-1D21-0000 is a AM8000 series servo motor from Beckhoff Automation. An optional holding brake is available on the motor. Its voltage rating is 24 Volts DC, which is the specification for the electrical release signal the brake requires to release the shaft and allow it to rotate. The servo drive used with the motor supplies this release signal. The brake prevents accidental shaft movement, which helps to prevent injury to personnel and damage to equipment. A multi turn encoder is installed for feedback. It is a rotary encoder that tracks the position of the shaft over multiple turns, and unlike single-turn encoders, can record the total number of rotations and provide complete positional feedback. The size of the mounting flange on the motor is 72 millimeters.

Standstill torque rating of the AM8031-1D21-0000 motor is 1.38 Nm and its standstill current is 1.95 Amps. The peak mechanical speed is 10,000 RPM. The peak nominal mains voltage is 480 Volts AC. Peak ratings for motor torque and current are 10.7 Amps and 6.07 Nm. Torque constant for the AC motor is 0.71 Nm/A and the voltage constant is 50 mV/min. Resistance of the motor windings is 12.6 Ohms and the winding inductance is 36 millihenry. At 115 Volts nominal input, the nominal speed is 1400 RPM, the nominal torque is 1.38 Nm and the nominal power output is 0.2 kilowatts. At 230 Volts nominal input, the nominal speed is 3300 RPM, the nominal torque is 1.36 Nm and the nominal power output is 0.47 kilowatts. At 400 Volts nominal input, the nominal speed is 6000 RPM, the nominal torque is 1.33 Nm and the nominal power output is 0.84 kilowatts.
