Product Description

The AM8032-1E20-0000 achieves relatively higher standstill values, high operating speeds, and low operational losses. With its brushless design, the AM8032-1E20-0000 achieves high mechanical efficiency because fewer mechanical losses are generated without a physical contact between the machine’s stator and rotor. When excited by a terminal voltage of 400 VAC, the AM8032-1E20-0000 achieves nominal working conditions. At this excitation voltage, the machine’s rotor reaches a rotational speed of 6000 rpm. At lower excitation voltages, the machine’s working speed also decreases. For instance, at 115 VAC supply, the machine’s working speed goes down to 1400 rpm.

As mentioned earlier, the AM8032-1E20-0000 has relatively higher standstill values compared to other AM servomotors by Beckhoff. At locked-rotor operation, the AM8032-1E20-0000’s standstill current reaches an RMS value of 2.95 amperes. At this standstill current, the machine’s equivalent output torque is 2.37 Nm. Without any surface-mounted fans, the AM8032-1E20-0000 preserves its standard rotor moment of inertia, weight, and frame length. Specifically, the AM8032-1E20-0000 has a rotor inertia of 0.85 Nm/A, a weight of 2.4 kg, and a frame length of 0.154 m. The AM8032-1E20-0000 has a built-in multi-turn OCT encoder that facilitates monitoring of the rotor’s angular and linear position during operation.

Although the AM8032-1E20-0000 achieves a nominal speed of 6000 rpm, the machine’s working speed may further be increased up to a peak speed of 10,000 rpm. One way to achieve this speed is to increase the machine’s excitation voltage while reducing the output torque. Naturally, AC motors’ torque and speed have an inverse relationship. To facilitate temperature equalization, the AM8032-1E20-0000 employs natural air convection. Since it is a relatively small and light motor, it is not necessary to install additional fans for surface cooling.
