Product Description:

The E3.SM.500-1YB0 is a synchronous servo motor produced by KEB as part of the SM Synchronous Servo Motors series. Designed for integration with the company’s digital drives, it converts electrical input into precisely regulated rotary motion for positioning, velocity control, and constant-torque tasks in industrial automation cells, conveyor stations, and pick-and-place equipment. The motor’s compact frame, resolver feedback, and sealed housing allow it to replace pneumatic or stepper solutions where tighter speed regulation and higher torque density are required.

Thermal management relies on the motor’s self-cooling aluminum housing, so no external blower or liquid circuit is required. At standstill, the electromagnetic stack delivers a stall torque of 29 Nm, giving adequate holding force for mid-range axes that must resist static loads. The rated mechanical speed is 1500 rpm, which matches standard gear ratios for indexing tables and slow conveyors. A cast end bell and compression glands seal the windings to an IP54 ingress rating, allowing operation in dusty production zones where occasional washdowns are present. The complete assembly weighs 17.4 kg, so it can be integrated on cantilevered mounts without overstressing light machine frames.

Rotor position is reported by a 2-pole resolver SSBH-15-E-5, enabling analog sine-cosine feedback to the controller for high-resolution commutation even during rapid reversals. The front face uses a B5 flange compatible with IFT5, simplifying alignment with IEC gearheads and couplings. Power is transmitted through a shaft supplied with a feather key, providing positive drive engagement while preserving quick serviceability. Motor frame code E3 indicates the stator length and electromagnetic loading used in this model. The unit is supplied without a holding brake to reduce inertia when dynamic stopping is handled by the drive’s regenerative brake chopper.
