AM8074 Servomotor  92 Nm and 129 Nm (standstill torque)

AM8074 | Servomotor 92 Nm and 129 Nm (standstill torque)

The highly dynamic AM8000 servomotors are characterised by high energy efficiency and low costs. The motor series offers overlapping torque ranges across all flange codes, allowing the best suited combination of servo drive and motor to be selected for every application.

The flange code F7 (AM807x) is supplemented by a further motor length: The new types with standstill torques of 92 Nm and 129 Nm (variant with external ventilation) cover the rated torque range from 19.1 to 93 Nm and complete the AM807x size for optimally coordinated, powerful drive solutions. As usual, there is a choice of a low-speed or high-speed winding in addition to the standard windings. Based on the drive axis requirements, the AX5000 servo drive can be selected according to the standstill current, which, for example with the low-speed winding, enables considerable cost savings. The high-speed winding can be used in applications with fast acceleration and/or high rated speed requirements. If necessary, the power density of the motors can be further increased with external axial ventilation.

Due to the high currents, not all coil types are available with One Cable Technology (OCT) via M40 speedtec® plug. For connection a terminal box is used if the current exceeds 40 A. The known options feather key or sealing ring are available for selection. Ready-made connecting cables and specially tailored planetary gears round off the range.
