Product Description

AM8141-3J21-0000 is a convection-cooled AM8100 series synchronous servo motor with electronic commutation. It is produced by Beckhoff Automation for industrial use. The motor has an aluminum housing which is coated with a power coat. The housing complies with IP65 requirements for robust solid and liquid ingress protection. The flange size is 87 millimeters and the motor length is 179 millimeters. The motor can support input supply ranging from 24 to 48 Volts DC. Performance specifications vary with input voltage. At 24 Volts DC supply, the nominal speed, torque and power are 300 RPM, 2.4 NM and 75 Watts respectively. At 48 Volts DC supply, the nominal speed, torque and power are 1000 RPM, 2.4 NM and 250 Watts respectively. Inductance of the motor windings measured at 1 kilohertz is 3.5 millihenry and the winding resistance is 0.9 Ohms.

Value of the standstill current is 8 Amps and the peak motor current is 36.2 Amps. Value of the standstill torque is 2.4 Nm and the peak motor torque is 9.13 Nm. The torque and voltage constants are 0.3 Nm/A and 21 mVmin. The temperature and humidity recommended for motor transport are -25 to 70 degrees Celsius and 5 to 95% respectively. The temperature and humidity recommended for motor storage are -25 to 70 degrees Celsius and 5 to 95% respectively. Only qualified personnel should perform motor maintenance and cleaning. Bearings used on the AM8141-3J21-0000 should be checked for noise every 2500 hours and should be replaced after 30,000 hours of operation. The motor shaft has a seal that should be lubricated after every 5000 operating hours. Beckhoff recommends using isopropanol or similar liquid for motor cleaning.
