Product Description:

The F2.SM.013-3410 is a three-phase synchronous servo motor built by KEB for the SM Synchronous Servo Motors series. The unit combines a permanent-magnet rotor with feedback from a 2-pole resolver to support closed-loop torque and speed control for positioning axes, feeders, and similar automation tasks. Separate cooling channels remove heat from the stator so the motor can deliver continuous output without exceeding insulation limits. A terminal box connection simplifies field wiring inside machine frames and keeps the external connections accessible where cable routing space is limited.

The motor’s continuous mechanical output reaches 9.7 kW, supplying enough shaft power for mid-range gantries and tool spindles. Its nominal operating velocity is 3000 rpm, allowing direct coupling to standard gear ratios while keeping servo response high. At that speed, the motor can deliver a continuous torque of 31.0 Nm while drawing a phase current of 20.6 A, so the inverter must be matched to the steady electrical demand. For vertical or suspended loads, the integrated electromagnetic brake secures the shaft with a holding capacity of 72 Nm. This holding torque helps prevent back-driving whenever the drive is disabled.

A short-term stall torque of 50 Nm supports acceleration peaks before thermal saturation occurs. The stator windings are designed for a line potential of 400 V, matching common industrial bus voltages and helping limit cable current. Electrical behavior is influenced by a winding inductance of 3.6 mH, which moderates current rise, and a winding resistance of 0.23 Ω, which contributes to copper losses at rated load. The brake is energized by 24 VDC at 1.67 A, and resolver feedback supports commutation and speed monitoring with compatible KEB inverters. This arrangement allows the motor to operate without a separate encoder assembly.
