Product description

The Siemens SIMOTICS S synchronous motor, model 1FK7042-2AK71-1RG0, is engineered for precision and efficiency in industrial automation. This motor delivers 0.94kW of rated power, operates on a 600V DC link, and provides a peak torque of 3Nm at a nominal speed of 6000rpm. It features natural cooling and an IMB 5 design (IM V1, IM V3), suitable for various mounting orientations. The motor has a smooth shaft with tolerance N and an IP64 degree of protection.

This unit is equipped with an AM20DQI absolute encoder, offering 20-bit +12-bit multi-turn resolution with the Drive-CLiQ interface.
