The EXA Series’ Mid-Torque Option
EXA-4030 Brushless Servo Motor: Genuine Energize Lab Hardware
The EXA-4030 is genuine Energize Lab hardware — “EXA-4030” and the Energize Lab logo are machined directly into a precision metal housing, visible across all 3 product photos. It sits between the compact EXA-4015 and the higher-torque EXA-4060 in Energize Lab’s precision EXA Series, all sharing the same machined-metal build quality.
At 30kg stall torque — double the EXA-4015’s rating — in a housing just slightly larger (38.5×21×32mm vs. 29×16.5×24.5mm) and heavier (65g vs. 35g), the EXA-4030 targets demanding robotic arm joints and mid-load actuation where the smaller EXA-4015 wouldn’t have enough torque. Its 50 RPM no-load speed, slower than the EXA-4015’s 60 RPM, reflects the same speed-for-torque tradeoff seen across Energize Lab’s other servo lines.
| Spec | EXA-4015 | EXA-4030 (this product) |
|---|---|---|
| Stall Torque | 15kg | 30kg |
| Dimensions | 29×16.5×24.5mm | 38.5×21×32mm |
| Weight | 35g | 65g |
| No-Load Speed | 60 RPM | 50 RPM |
| Stall Current | 1.2A | 4A |

What It Is, and Where It Goes
The EXA-4030 is a compact brushless smart servo motor — a self-contained rotary actuator with its own control electronics, built for mid-load joints inside a larger robotic or automation system.

From the Same Manufacturer Behind Eilik
The EXA-4030 is genuine Energize Lab hardware from its precision EXA Series — a different, brushless-motor product line from the cored-motor EM and EH servos used in Energize Lab’s consumer robots. It is not confirmed to be the servo inside Eilik or Panxer; what it shares with them is the same manufacturer and the same TTL control protocol.

The Company Behind This Hardware
Energize Lab hasn’t published an EXA-4030-specific demo — this is precision/industrial hardware, not consumer content. Honestly labeled: these are official Energize Lab videos of Eilik and Panxer, its consumer robots, included here only to show Energize Lab is a real, established manufacturer — not as a claim that this exact part is used inside them.
