SPIDER Automation | GT2205 2300KV CW Brushless Outrunner Motor | N52 Magnets for 5-Inch FPV Multirotor Propulsion
Description
The GT2205 2300KV CW Brushless DC Outrunner Motor is designed for compatible FPV racing drones, multirotor aircraft and compact brushless propulsion systems using 5-inch propellers. It features a 2300KV speed constant and curved N52 high-temperature magnets. The motor is specified for 3S–4S LiPo battery configurations, with a 40–60A ESC range identified in the supplied configuration information.
Its mechanical assembly incorporates quality bearings, a strong retaining C-clip and a 4mm shaft. The motor has a listed weight of approximately 35g and an internal resistance of 65mΩ. The source specifies maximum efficiency above 81% and a 30A maximum-efficiency current. These values are useful for propulsion-system evaluation, but actual current draw and efficiency depend on the selected battery voltage, propeller load and operating conditions.
This is the CW (clockwise) rotation version. The package includes four socket-head cap (Allen) mounting bolts. A separate compatible propeller adapter may be required depending on the propeller mounting arrangement. The source also identifies limited exposed cooling fins, making airflow and thermal management important considerations during high-load operation.
Motor Configuration & Electromagnetic Design
The GT2205 motor combines a 2300KV speed constant with curved N52 high-temperature magnets. The magnet geometry is described as thin, wide and curved, forming part of the motor’s electromagnetic design. Its speed constant is a nominal no-load reference and should not be interpreted as a guaranteed loaded operating speed.

Mechanical Construction & Shaft Retention
The motor uses a compact mechanical assembly with quality bearings and a retaining C-clip. The C-clip helps retain the shaft assembly during operation, while the bearing arrangement supports smooth rotation. Its approximately 35g weight makes it suitable for multirotor designs where propulsion component mass is an important consideration.

Electrical Compatibility & Propulsion Configuration
The GT2205 2300KV motor is specified for 3S–4S LiPo battery systems. The supplied configuration information identifies a 40–60A ESC range and 5-inch propellers. These are system-selection references rather than a guarantee that every ESC or propeller within those categories will be suitable. Actual current demand must be evaluated with the intended battery and propeller combination.
- Battery Compatibility: Specified for 3S and 4S LiPo battery configurations.
- ESC Range: A 40–60A ESC is identified in the source configuration information.
- Propeller Size Reference: 5-inch propeller configuration.
- Maximum-Efficiency Current: 30A listed at the maximum-efficiency operating point.
- Internal Resistance: 65mΩ source-listed motor resistance.
- Maximum Efficiency: Greater than 81% as stated in the source specifications.
- Propulsion Matching: Battery voltage, ESC capability and propeller loading should be evaluated together before operation.
Thermal Management & Cooling Considerations
The supplied description identifies limited exposed cooling fins as a potential limitation of the motor’s self-cooling arrangement. For this reason, airflow and operating temperature should be considered when selecting the motor’s propeller, ESC and installation position. High-load operation should be evaluated under the actual aircraft configuration rather than relying on the motor’s speed constant or efficiency figure alone.
- Limited Exposed Cooling Fins: The source notes a lack of prominent exposed fins for heat dissipation.
- Airflow Consideration: Allow suitable airflow around the motor during operation.
- Load Matching: Select a propeller that keeps motor current and temperature within verified operating limits.
- Thermal Monitoring: Check motor temperature during initial testing and after changes to battery voltage or propeller configuration.
- Installation Clearance: Avoid mounting arrangements that unnecessarily obstruct airflow around the motor.

Installation & Operating Recommendations
- Verify Battery Voltage: Use a compatible 3S–4S LiPo configuration and confirm that the selected battery, ESC and motor are suitable for the intended operating conditions.
- Select a Suitable ESC: The source recommends a 40–60A ESC range. Verify the ESC’s voltage rating, current capability and cooling requirements before installation.
- Match the Propeller: Use a compatible 5-inch propeller configuration and evaluate actual current draw under load before regular operation.
- Check Adapter Compatibility: Confirm that the separate propeller adapter matches the motor’s 4mm shaft and the selected propeller hub.
- Confirm Rotation Direction: This is the CW version. Verify the required motor direction and propeller orientation for the aircraft layout.
- Secure Motor Mounting: Use the included four Allen bolts with compatible frame mounting points. Confirm screw length and clearance before tightening.
- Check Shaft Retention: Inspect the C-clip and shaft assembly for correct seating before operation.
- Allow Adequate Airflow: Avoid installations that obstruct airflow around the motor, particularly because the source notes limited exposed cooling fins.
- Monitor Temperature and Current: Check motor temperature and current draw during initial testing, especially when changing propeller size or battery configuration.
- Test Before Flight: Verify rotation, mounting security and ESC response in a controlled test environment before installing the aircraft’s propellers for flight.
