Motor ratings and what they mean for the axis
The 1FL2306-2AC11-1MB0: Rated power is 1 kW at 2000 rpm with a continuous torque of 4.78 Nm — the holding brake holds 5 Nm at standstill, so the brake rating exceeds the motor's continuous torque by about 5 %, enough to keep a vertical load from drifting when power is removed. Supply voltage is 400 V three-phase AC, standard for European industrial mains. The 65 mm shaft height and shaft key with tolerance N mean it fits the common mounting pattern for this frame size. The 21-bit absolute encoder (AM21bit) gives 2,097,152 positions per revolution — enough resolution for positioning applications that need sub-arcminute accuracy without a separate encoder cable.
Matching drive and integration
This motor is part of the 1FL2 servomotor family designed to pair with the SINAMICS S200 drive series — the motor and drive share a common feedback interface and tuning parameter set, so commissioning is a matter of entering the motor code into the drive. IP65 with oil seal means the motor body and shaft seal withstand washdown and coolant splash — suitable for machine-tool spindles, packaging lines, and food-grade conveyors where the motor is in the wet zone. The angular connector exits at 90° to the motor axis, saving axial space in tight enclosures. With holding brake, the motor holds position when the drive is disabled — no external brake relay needed for vertical-axis safety.
Lifecycle and compliance
RoHS compliant since January 2018; REACH candidate-list information is published by Siemens. No UL or CSA listing is stated in the record — confirm with the factory if UL recognition is required for the installation. Product class C means this is manufactured to order — not a stocked shelf item. Lead time and quantity pricing are confirmed at RFQ against the BOM.
