Product Description:
The AM8041-0D20-0000 belongs to AM servitor’s larger motor classes, boasting a base length of 132 mm, a flange size of 87 mm, and a weight of 2.8 kilograms. Although it’s nowhere as big as other heavy-duty motors on the market, its compact construction makes it the best choice for driving loads in relatively small systems. During operation, the AM8041-0D20-0000 requires a terminal voltage of at least 400 Vrms to achieve nameplate values. The nameplate values of this motor are 3000 min^-1, 2.3 Nm, 0.72 kW, and 1.6 A. With its impressive OCT absolute encoder, the rotor’s angular position can precisely be determined during operation, including the number of elapsed revolutions.
The AM8041-0D20-0000 has a smooth shaft, which accommodates the highest number and type of loads. Depending on the design of the system, the machine may be installed at different mounting positions. Specifically, the AM8041-0D20-0000 supports the following flange variations: IM V1, IM V3, and IM B5. The first two flange installment variations put the motor in a vertical position, while the last one puts the motor in a horizontal orientation. IM V1 puts the drive side facing upwards, while IM V3 type of installation makes the drive shaft face downward.
At most, the AM8041-0D20-0000 can achieve a peak speed of 9000 rpm, a peak voltage supply of 480 V, a peak current of 8.3 A, and a peak torque of 9.67 Nm. For equivalent-circuit analyses, the motor may be modeled in terms of its winding resistance and reactance. The AM8041-0D20-0000’s datasheet provides the values for the machine’s phase-phase resistance and inductance. Specifically, at 1 kHz and 20 degrees C, the winding resistance is 22.5 ohms, while the winding inductance is 83.1 mH.
