1 kW at 2000 rpm — what the ratings mean on the line
The 1FL6062-1AC61-0AB1 is a Siemens SIMOTICS S-1FL6 servo motor rated 1 kW at 2000 rpm rated speed, with a stall torque M0 of 6 Nm and a rated torque MN of 4.78 Nm. That 4.78 Nm is what the motor delivers continuously at rated speed — the 6 Nm stall figure is available at zero speed for acceleration or holding, but the thermal limit at speed settles at the lower number. Operating voltage is 400 V three-phase AC, which matches the standard European industrial mains. The motor is designed to pair with SINAMICS V70 and V90 servo drives — the encoder interface is an incremental TTL with 2500 increments per revolution, giving position feedback resolution adequate for most conveyor, pick-and-place, and packaging machine axes.
IP65 with holding brake — washdown-ready, holds position unpowered
IP65 degree of protection means the motor body is sealed against dust ingress and low-pressure water jets from any direction — suitable for food processing lines, washdown areas, or outdoor installations under cover. The sealing ring at the shaft face is the critical wet-end barrier; if the seal is damaged during installation, the IP rating is lost. The integrated holding brake locks the rotor when the drive is de-energized, preventing the load from drifting on a vertical axis or during a power loss. The brake is spring-applied, electrically released — it engages automatically when power is removed, so no separate control signal is needed for fail-safe hold. Shaft height is 65 mm with a feather key and tolerance N, which is the standard fit for most coupling and pulley interfaces in this frame size. The key transmits torque from the shaft to the load; tolerance N means the key sits with a normal clearance fit, not an interference fit.
This is a spare part — the description explicitly flags it as such, which means it is stocked and sold as a replacement unit for existing machines, not as a new-build OEM component. The form factor and electrical interface match the original S-1FL6 series motors already in the field. Sourced through independent distribution channels; no minimum order quantity is assumed unless specified at RFQ.
