Description

The Surpass Hobby 3650 ROCKET motor is engineered for high-torque applications requiring durability and consistent power delivery. Its sensorless design simplifies integration and enhances long-term reliability by eliminating hall sensor failure points, making it suitable for rugged use in RC cars, boats, and heavy-lift multirotor drones.

Built with a precision-balanced rotor and high-grade materials, the motor ensures smooth operation at high RPMs, minimizing vibration for improved performance and component longevity. The robust housing and multi-mounting system (compatible with M3 or M4 screws) provide a universal fit for 1/8th scale platforms and other custom builds.

Key Features

  • Waterproof & Durable: Sealed construction protects internal components from moisture, dust, and debris.
  • High-Efficiency Windings: High-purity copper windings reduce resistance for optimal power conversion and thermal management.
  • Precision-Balanced Rotor: Dynamically balanced for ultra-smooth rotation, reducing vibration and maximizing reliability at high speeds.
  • Oversized ABEC Bearings: High-RPM bearings ensure smooth shaft rotation and extended motor life under heavy loads.
  • Versatile Mounting: Universal multi-mount system accommodates M3 or M4 screws for flexible installation in various frames.
  • Gold-Plated Shaft: 3.175mm shaft with gold plating offers superior corrosion resistance and reliable power transfer.

Applications

  • High-power 1/8th scale RC buggies, truggies, and short-course trucks.
  • Large-scale RC boat and marine propulsion systems.
  • Heavy-lift multirotor drones and UAVs requiring high-torque, waterproof motors.
  • Custom ground vehicle and robotics platforms needing robust, sensorless brushless power.

Frequently Asked Questions

What is the maximum voltage and current for this Surpass Hobby 3650 motor?

This motor is rated for a maximum working voltage of less than 24V and a continuous current of 38 amps. It is suitable for 4S to 6S LiPo battery configurations commonly used in high-performance RC applications. Always ensure your Electronic Speed Controller (ESC) is rated to match or exceed these current specifications.

Is this a sensored or sensorless brushless motor?

This is a sensorless brushless motor. It operates without internal hall sensors, which simplifies wiring and increases durability in harsh environments. Sensorless motors are compatible with most modern sensorless ESCs and provide smooth operation from mid to high RPMs.

What is the shaft diameter and is it compatible with standard pinions?

The motor features a 3.175mm (1/8 inch) diameter gold-plated output shaft. This is a standard size for 1/8th scale RC vehicle pinions and many drone prop adapters. Ensure any pinion or adapter you use is specifically bored for a 3.175mm shaft for a secure fit.

Can this waterproof motor be used in marine or wet conditions?

Yes, the motor is constructed with a waterproof seal, making it suitable for use in RC boats, amphibious vehicles, or drones operating in rain, snow, or muddy conditions. The sealing protects the internal bearings and windings from water ingress and corrosion.
