120 Brushless Motor for Electric Paramotor: The 15kW Inrunner That Powers Silent Flight
A 120 brushless motor for electric paramotor applications is a large-format brushless DC inrunner — typically in the Φ120mm diameter class — designed to deliver 15kW of continuous power, 12N·m of peak torque, and up to 40kg+ of static thrust with the right propeller. It replaces the traditional 2-stroke gasoline engine in a paramotor (powered paraglider) frame, offering silent, emission-free, low-maintenance flight. The X-TEAM 12095 Inrunner (130KV, IP57 waterproof) is purpose-built for this role — and also spans electric surfboards, underwater thrusters, and heavy-lift UAVs.
If you are building an electric paramotor (ePPG), selecting a commercial propulsion system, or sourcing OEM motors for ePPG production, this article covers every specification, engineering consideration, and real-world application insight you need.
What Makes a 120-Size Brushless Motor Right for Paramotors?
Electric paramotors demand a specific combination of attributes that smaller drone motors simply cannot provide:
- Sustained high power: A paramotor pilot with gear typically weighs 90–130 kg total takeoff mass. Achieving a safe 1.2:1 thrust-to-weight ratio requires 12–18 kW of propeller power — right in the 120-class motor’s sweet spot.
- Low KV for large props: Paramotor propellers run 34–50 inches in diameter at 3,000–5,500 RPM. The 130KV winding of the X-TEAM 12095 on 14S–20S (52V–74V) spins directly in that range — no gearbox needed.
- Robust thermal management: 15kW continuous generates serious heat. The 12095’s IP57-rated sealed construction with integrated water-cooling jacket keeps stator temperatures stable even during extended climb-outs.
- Ingress protection: Paramotors fly in mist, light rain, and coastal humidity. IP57 means protection against dust and temporary water immersion — critical for real-world reliability.

12095 vs. 12090: What’s the Difference?
Shoppers comparing 120 brushless motor paramotor options will encounter both 12090 and 12095 form factors on the market. Here is the practical distinction:
| Feature | X-TEAM 12095 (Inrunner) | Typical 12090 (Outrunner) |
|---|---|---|
| Rotor Type | Inner rotor — compact, higher RPM capable, easier to seal | Outer rotor — larger rotating mass, higher inertia |
| Stator Length | 95 mm (longer stator = more torque capacity) | 90 mm |
| Weight | 3.6 kg | 2.8 – 3.5 kg (varies by brand) |
| KV Options | 130KV standard; custom KV available | 50KV, 80KV, 130KV (varies) |
| Waterproof Rating | IP57 (factory rated & tested) | Often unrated or IPX4 |
| Sealing | Inrunner naturally easier to seal; no rotating can exposure | Outrunner can requires gap sealing |
| Cooling | Internal water jacket — consistent thermal performance | Air-cooled or optional water jacket |
| Paramotor Suitability | Excellent — compact, sealed, direct-drive compatible | Good — but heavier rotating mass and sealing challenges |
The 12095’s inrunner architecture gives it an edge for paramotor use: the sealed stator housing simplifies dust and moisture protection, and the longer 95mm stator provides additional continuous torque capacity compared to 90mm-class competitors — a meaningful difference during sustained climbs at full throttle.
KV Selection for Electric Paramotors: 130KV on 14S–20S
KV selection is the most critical decision when matching a 120 brushless motor to a paramotor. The formula is straightforward:
Propeller RPM = KV × Battery Voltage × 0.85 (accounting for ~85% efficiency under load)
| Battery (Series Cells) | Nominal Voltage | Estimated RPM @ 130KV | Typical Prop Size |
|---|---|---|---|
| 14S LiPo | 51.8V | ~5,720 RPM | 34″–38″ 2-blade |
| 16S LiPo | 59.2V | ~6,540 RPM | 34″–40″ 2-blade |
| 18S LiPo | 66.6V | ~7,360 RPM | 36″–42″ 2- or 3-blade |
| 20S LiPo | 74.0V | ~8,180 RPM | 36″–46″ 2- or 3-blade |
For a typical 100–110 kg paramotor setup: 16S (59.2V) with a 36-inch carbon propeller is a well-proven combination. At 130KV, this delivers approximately 25–35 kg of static thrust — well above the 1.2:1 thrust-to-weight minimum for safe flight. The 150KV variant (available on request) shifts the RPM band higher for lighter pilots or 14S configurations who prefer a smaller-diameter prop.

ESC and Battery Pairing for the 12095
A 15kW motor demands an ESC and battery system that can deliver without voltage sag or thermal shutdown. Here is the recommended pairing:
| Component | Minimum Specification | Recommended Specification |
|---|---|---|
| ESC | 300A continuous, 22S-compatible | 400A+ continuous, 24S-compatible, with active cooling |
| Battery | 14S 20Ah LiPo (approx. 1 kWh) | 16S–18S 25–30Ah LiPo or Li-Ion (approx. 1.5–2 kWh) |
| Flight Time (cruise @ 40% throttle) | ~15–20 minutes (1 kWh pack) | ~25–35 minutes (2 kWh pack) |
| BMS / Monitoring | Per-cell voltage telemetry | Full CAN bus BMS with current, temperature, SoC telemetry |
Critical note: The 12095 can pull up to 300A peak. A hobby-grade 200A ESC will fail under sustained paramotor loads. Always overspec the ESC by at least 30% above the motor’s rated maximum, and ensure active cooling (fan or liquid) for the controller as well.
Applications Beyond Paramotors
One of the advantages of the X-TEAM 12095 platform is its versatility across multiple high-power electric mobility applications. The same motor architecture that powers a silent paramotor also drives:
- Electric surfboards & eFoils: Direct-drive water propulsion — the IP57 rating handles salt spray and temporary submersion. This is the motor’s primary production application, with thousands of units deployed globally.
- Underwater thrusters & ROVs: The sealed inrunner design, combined with water cooling, makes it ideal for sustained underwater operation.
- Electric jet boats: High torque at low-to-mid RPM delivers strong acceleration without gear reduction.
- Heavy-lift UAVs & eVTOL prototypes: The 15kW power class supports multi-rotor configurations for payloads up to 50–80 kg.
This cross-application pedigree means the 12095 benefits from engineering refinements driven by high-volume surfboard production — translating to better reliability, tighter tolerances, and more competitive pricing for paramotor builders.
Frequently Asked Questions
Can a 120 brushless motor really replace a gas paramotor engine?
Yes — and in many ways it is superior. A typical 2-stroke paramotor engine produces 15–20 kW but at ~80% efficiency from fuel to thrust, with significant noise (90–100 dB), vibration, and maintenance requirements. The X-TEAM 12095 at 15 kW electric delivers comparable real-world thrust with zero emissions, ~70 dB noise levels, no fuel mixing, no pull-starting, and dramatically lower vibration — which reduces fatigue on both the pilot and the airframe. The tradeoff is flight time: a 2 kWh battery pack provides 25–35 minutes vs. 2+ hours from gasoline. But for training, recreational flights, and noise-restricted areas, electric is the clear winner.
What propeller size works best with a 130KV 12095 on a paramotor?
For 16S (59.2V) operation, a 34–38 inch 2-blade carbon fiber propeller with 10–14 inch pitch is the most common configuration. This delivers 25–35 kg of static thrust depending on prop design and battery voltage sag. At 18S–20S, you can step up to 40–46 inch props for higher thrust at the cost of higher current draw. Always verify propeller balance — vibration at 5,000+ RPM with a 36-inch prop is extremely dangerous if not perfectly balanced.
Is the 12095 waterproof enough for paramotor use?
Yes. The IP57 rating means the motor is protected against dust ingress (level 5) and temporary immersion in water up to 1 meter depth for 30 minutes (level 7). For paramotor use — where the motor may encounter rain, mist, morning dew, or coastal humidity — IP57 provides ample protection. It is not rated for permanent underwater operation (that would require IP68), but it exceeds what any gas paramotor engine offers in terms of environmental sealing.
How much does a complete 120 brushless motor paramotor system weigh?
A typical electric paramotor power system built around the X-TEAM 12095 weighs approximately:
- Motor: 3.6 kg
- ESC + wiring: 1.5–2.0 kg
- Battery (16S 25Ah LiPo): ~10–12 kg
- Propeller + mount + frame adapter: ~1.5–2.0 kg
- Total power system: ~17–20 kg
Adding the harness, cage, and wing, a complete ready-to-fly electric paramotor typically weighs 25–30 kg — comparable to a gas paramotor (22–28 kg with fuel). The battery weight is the main penalty, but it is steadily improving with newer high-energy-density Li-Ion cell formats.
Can I get the 12095 with a different KV or custom shaft?
Yes. X-TEAM offers full OEM customization on the 12095 platform: custom KV windings (any value within the 22V–85V operating range), modified shaft dimensions (diameter, length, keyway), custom connectors and cable lengths, sensored Hall-effect variants for precision control, and private-label branding.
