Product details

What the 1FK7044-7AF71-1 is

The 1FK7044-7AF71-1...: The 1FK7044-7AF71-1 is a SIMOTICS S 1FK7 High Dynamic synchronous servo motor in the 4.0 Nm, 100K frame size, with a 3000 rpm rated speed and 1.1 kW shaft power under natural cooling. Its B5 flange mounting and power/signal connector outlet rotatable through 270° let a panel builder dress the lead exit into an enclosure regardless of drive-side cable routing — the rotation is what matters at install time, not at order time.

Sourcing posture for an EOL 1FK7 frame

Stock is sourced per RFQ through independent distribution rather than franchised line, with current availability and pricing confirmed at quote time — what maintenance needs is a traceable spare that drops onto the existing SINAMICS drive tuning profile without a re-commission pass.

Frequently asked questions

What does the description on record say for 1FK7044-7AF71-1?

The description lists it as a spare-part SIMOTICS S synchronous servo motor, 1FK7 High Dynamic, 4.0 Nm at 100K, 3000 rpm, 1.1 kW, naturally cooled, IM B5 (V1, V3) flange, with a rotatable power/signal connector plug.

What replaces 1FK7044-7AF71-1 in the SIMOTICS S line?

A pin-compatible alternative would have to match the 1FK7 series, 4.0 Nm torque, 3000 rpm rated speed, 1.1 kW, and natural cooling — outside those four parameters a swap requires drive firmware and encoder feedback review.
