THOR 2318 Brushless Gear Motor

The MAXYNOS THOR 2318 is the most compact and lightweight member of the THOR Series — a high-efficiency 23 mm Brushless DC Outrunner Motor integrated with a 24 mm precision planetary gearbox. Engineered for applications where space, power, and performance must coexist, this motor delivers exceptional torque and control in a remarkably small footprint.

Available in two kV ratings, the 1250 kV version is optimized for speed and responsiveness, while the 625 kV (87 W) configuration provides stronger torque output and superior efficiency under sustained load. The THOR 2318 is also offered in three gear ratios — 1:19, 1:27, and 1:51 — giving designers the flexibility to fine-tune speed and torque for their specific robotic or automation systems.

Despite its miniature size, this motor is built with an outrunner rotor design, ensuring smooth operation, high torque density, and excellent heat dissipation. The metal planetary gearbox provides precise motion control, low noise, and impressive durability.
With a total weight of just 70 g (1:19 & 1:27) and 77 g (1:51), the THOR 2318 is the perfect choice for compact robots, smart devices, and advanced automation mechanisms that require power without compromise.

Planetary Gearbox – Exact Reduction Ratio:

  • Gear ratio 19:1 → Exact reduction ratio 19.20:1
  • Gear ratio 27:1 → Exact reduction ratio 26.85:1
  • Gear ratio 51:1 → Exact reduction ratio 50.89:1

Planetary Gear Motor Weight:

  • THOR 2318 gear ratio 19:1 weight = 70 g
  • THOR 2318 gear ratio 27:1 weight = 70 g
  • THOR 2318 gear ratio 51:1 weight = 77 g

Planetary Gearbox Speed (RPM) Calculations:

  • Motor Speed (RPM) = (Motor KV value) × (Applied Voltage) → Example: 1250KV Motor speed at 14V → 1000 × 14 = 17,500 RPM
  • Gearbox Speed (RPM) = Motor speed ÷ Exact reduction ratio → Example: Gear speed (RPM) at Ratio 27:1 & 14 Volts → 17,500 ÷ 26.85 = 651 RPM

Inside THOR 2318

THOR 2318 comes equipped with a premium planetary gearbox, providing smooth acceleration, minimal backlash, and enhanced load handling — making it the ideal choice for robotics, RC vehicles, and smart automation projects.

THOR series offers an exceptional size-to-power ratio, peak torque output, and rugged reliability — engineered for creators, builders, and professionals who demand nothing but the best.

High Power Outrunner

Next-Generation Brushless Motor Technology Replaces traditional brushed motors with a more efficient, longer-lasting solution. Offers reduced maintenance, lower heat, and higher reliability over time.
High-Torque OutRunner Design: Featuring an external rotor that spins around the stator, this motor generates significantly higher torque at lower speeds. This design improves thermal stability and energy efficiency, eliminating the need for bulky gearing and simplifying your project's design.

Motor Dimensions in mm

Motor Connection Guide

Connecting your brushless motor to the ESC is simple: both components have three wires.

  • The middle wire of the motor must always connect to the middle wire of the ESC. Do not change this connection.
  • You can swap the left and right wires if you want to reverse the motor’s rotation direction.

Note: Only one motor can be connected to one ESC. Therefore, each motor requires a dedicated ESC.

FAQs
