AM8033-0F20-0000

Product Description:

The AM8033-0F20-0000 integrates an accurate OCT absolute multi-turn encoder during operation. This feedback system monitors the position of the rotor in terms of its angular displacement with respect to some reference. Absolute encoders achieve a higher degree of accuracy, which makes them perfect for highly accurate systems and applications. Encoders that are of the multi-turn type can also keep track of the rotor’s number of revolutions along with its instantaneous position. OCT encoders by Beckhoff come with only a single cable, combining both the encoder cable and power cable for the motor. With this type of feedback system, this servomotor can control loads and drive other components reliably.

When operated at a speed lower than 100 rpm, the AM8033-0F20-0000 can maintain its standstill values. The standstill torque of this three-phase motor is 3.22 Nm, while its standstill current is 4.1 amperes. The standstill current provides a good estimation of the magnitude of the inrush current experienced during the starting transient period of the motor. This value, in effect, becomes the foundation of the protection devices and system built for the motor itself. To vary the motor’s speed, the excitation voltage or frequency may be changed. Between these options, however, it is more practical to change the excitation voltage rather than the frequency, since the frequency influences the dynamic response of the motor.

The AM8033-0F20-0000s may operate in a voltage range below 480 V but not less than 100 V. At the nominal voltage of 400 V, the machine achieves a steady-state RMS current of 3.6 amperes. At this current draw, the motor supplies 1.7 kilowatts and transmits 2.7 Nm. The corresponding shaft speed at this rated condition approaches 6000 rpm.
