The EH Series’ High-Torque Flagship
EH-30 TTL Smart Servo Motor: Genuine Energize Lab Hardware
The EH-30 is the largest and strongest member of Energize Lab’s EH Series, and the most clearly branded product photo set of any Energize Lab servo xBoom carries — all 3 images show the Energize Lab logo and “EH-30” molded directly into the black housing. At 30kg of stall torque, it delivers ten times the smaller EH-3’s rating, in the same 48 × 26 × 36mm footprint Energize Lab also uses for its EM-10 (a different series, distinct part).
Notably, the EH-30 draws a maximum of 2A at stall — less than the EM-10’s ~3A — while producing three times the torque (30kg vs. 10kg) in the same-sized housing, according to each product’s own published figures. TTL serial control keeps it consistent with the rest of Energize Lab’s servo lineup, though at 12V input it isn’t a direct electrical swap for the smaller 8V EH-3.
| Spec | EH-30 (this product) | EH-3 |
|---|---|---|
| Stall Torque | 30kg | 3kg |
| Dimensions | 48×26×36mm | 28.5×12×20mm |
| Weight | 70g | 11g |
| No-Load Speed | 50 RPM | 120 RPM |
| Voltage / Current | 12V / 2A | 8V / 1A |

What It Is, and Where It Goes
The EH-30 is a high-torque smart servo motor — a self-contained rotary actuator with its own control electronics, sized for the heaviest joints in a robotic assembly, not a standalone product on its own.

The Flagship of a Genuine Energize Lab Series
The EH-30 is the highest-torque member of Energize Lab’s EH Series, sharing its TTL control interface with the smaller EH-3. It is not the specific servo Energize Lab has shown inside Eilik — that direct confirmation exists for the EM-3, a different series — but it comes from the same manufacturer, whose ecosystem also includes Panxer, the larger, more mechanically demanding robot Eilik itself has been shown driving.
