THOR 3548 Brushless Gear Motor

The MAXYNOS THOR 3548 (Titan High-power Outer Rotor) series is a premium line of Planetary Gearbox Brushless DC Motors engineered for superior performance, where the Output Rotor placed outside the motor core to obtain highest torque and provide the maximum limit of power consumption, efficiency and the best size to power ratio.

Key Features:

  • High-efficiency 35mm diameter Brushless DC Outrunner Motor integrated with a 36 mm planetary gearbox
  • Available in two KV configurations, the 900KV (1000 W) 18 volts model provides faster rotational speed and and high torque, while the 790KV (840 W) 20 volts version is optimized for high torque and greater energy efficiency.
  • Equipped with 3.5mm bullet connectors and 8mm D-shape shaft provides a secure, non-slip fit for gears, pulleys, and sprockets, ensuring maximum torque transfer.
  • Featuring an outrunner rotor design that places the rotor outside the motor core, it delivers exceptional torque output, stable operation, and superior thermal balance. 
  • All-metal planetary gearbox is available in three gear ratios (14:1, 19:1, and 51:1) providing high torque, low backlash, low noise, and outstanding durability where a higher gear ratio results in slower output speed but greater torque, allowing the motor to deliver powerful and precise motion control across various applications.

Planetary Gearbox – Exact Reduction Ratio:

  • Gear ratio 14:1 → Exact reduction ratio 13.73:1
  • Gear ratio 19:1 → Exact reduction ratio 19.20:1
  • Gear ratio 51:1 → Exact reduction ratio 50.89:1

Planetary Gear Motor Weight:

  • THOR 3548 gear ratio 14:1 weight = 349 g
  • THOR 3548 gear ratio 19:1 weight = 350 g
  • THOR 3548 gear ratio 51:1 weight = 389 g

Planetary Gearbox Speed (RPM) Calculations:

  • Motor Speed (RPM) = Motor KV value × Applied Voltage → Example: 900KV Motor speed at 14V → 900 × 14 = 12,600 RPM
  • Gearbox Speed (RPM) = Motor speed ÷ Exact reduction ratio → Example: (Gear speed (RPM) at Ratio 19:1 & 14 Volts) → 12,600 ÷ 19.2 = 656 RPM

Motor Connection Guide

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

  • Connect each of the three motor wires to the three ESC output wires — left, middle, and right.
  • 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.

FAQs

Do you ship your products Worldwide?

Yes. We ship worldwide and process most orders within 24 hours for fast and secure delivery.

What makes the MAXYNOS THOR 3548 motor different from smaller models?

The THOR 3548 offers higher power output (up to 1000W) and torque compared to smaller motors like the 2826 and 2830. It is designed for larger robotics, RC vehicles, and automation projects that need more strength and load capacity.

What gearbox ratios are available for the THOR 3548?

The THOR 3548 comes in three gearbox ratios: 14:1 (13.73 exact), 19:1 (19.20 exact), and 51:1 (50.89 exact). This flexibility allows you to select the right balance between speed and torque for your project.

Which ESC is recommended for the THOR 3548?

For safe operation, we recommend the Maxynos 45A ESC or higher. This ensures the motor performs reliably at its rated voltage and current levels, whether you choose the 900KV or 790KV version.

What applications is the THOR 3548 best suited for?

This motor is ideal for heavier robotics projects, RC aircraft, electric vehicles, and advanced automation systems. Its planetary gearbox provides smooth acceleration and precise handling under demanding loads.

What is the weight of the THOR 3548 motor?

The weight depends on the gearbox ratio. The 14:1 version weighs 349 g, the 19:1 version weighs 350 g, and the 51:1 version weighs 389 g. This makes it a powerful yet compact choice for high-performance builds.
