SIMOTICS S Synchronous Motor 20Nm Nominal Torque 3000rpm Nominal Speed IP65 Protection 22-bit Multi-turn Absolute Encoder with Drive-CLIQ Holding Brake

Product description

The Siemens 1FT7084-5AF71-1FB1 is a SIMOTICS S Synchronous motor from the 1FT7 series. It boasts a nominal torque (M0) of 20Nm (at 100K), a nominal speed (NN) of 3000rpm, and a nominal power (PN) of 4.55kW. This naturally cooled motor is built to IP65 protection standards, features frame size IMB 5 with a conventional flange (1FT6/1FK7 compatible), and a rotatable power connector. It is equipped with an ABSOLUTE ENCODER 22 BITS MULTI TURN (AM-22-DQ) with DRIVE-CLIQ INTERFACE, a shaft with a fitted key, and includes a HOLDING BRAKE with accuracy tolerance N. Vibration severity is grade A.

This motor is ideal for high-performance applications requiring precise and continuous positional feedback, even after power cycles, due to its multi-turn absolute encoder. Applications include complex robotics, automated machinery, and machine tools where precise motion and holding capabilities are essential.

Frequently asked questions

What is the advantage of the multi-turn encoder on the Siemens 1FT7084-5AF71-1FB1 motor?

The AM-22-DQ 22-bit multi-turn absolute encoder allows the motor to track position accurately through multiple revolutions and even after power loss. This is crucial for applications with complex movement paths or where axis reset is undesirable.
