Product Description

AM8552-1J21-0000 is a brushless industrial motor from Beckhoff Automation. It belongs to the AM8500 series. It is a servo motor with a multi turn encoder. The encoder is a sensor that measures motor position and speed. A cable connecting the motor to the servo drive carries feedback from the motor to the servo drive. The drive uses real-time information about motor parameters to adjust its output and minimize the difference between desired and actual motor parameter values. This is closed loop control that uses feedback to ensure accuracy for motor parameters. The cable connecting the motor to the drive also carries motor power supplied by the drive. AM8552-1J21-0000 is an AC motor that requires three-phase AC power. It supports a wide range for input from 100 to 480 Volts AC.

This gives operators the option of operating the motor according to application requirements. Speed rating of the motor is 1000 RPM at 115 Volts, 2200 RPM at 230 Volts, 4000 RPM at 400 Volts and 4500 RPM at 480 Volts. Power output of the AM8552-1J21-0000 motor is 0.83 kilowatts at 115 Volts, 1.73 kilowatts at 230 Volts. 2.89 kilowatts at 400 Volts and 3.16 kilowatts at 480 Volts. The nominal torque is 7.9 Nm at 115 Volts, 7.5 Nm at 230 Volts, 6.9 Nm at 400 Volts, and 6.7 Nm at 480 Volts. The motor connector is an M23 speedtec and the motor requires a single cable for both power and feedback signals. The peak motor speed and input are 9000 RPM and 480 Volts respectively. Moment of inertia for the main rotor is 11.3 kg cm2. Weight of the unit, including the brake, is 7.9 kilograms.
