SPIDER Automation | 2312 920KV CW Brushless Outrunner Motor | 220W Drone & Multirotor Propulsion
Description
The 2312 920KV CW Brushless DC Outrunner Motor is a compact propulsion motor designed for compatible drones, quadcopters and multirotor aircraft. It features a 12N14P motor configuration with 14 poles, a 920KV speed constant and a listed maximum power rating of 220W. The motor is specified for 2S–4S LiPo battery systems and is intended for integration into appropriately designed brushless propulsion assemblies.
Its mechanical construction combines a CNC-machined aluminium outer housing, Japanese EZO bearings and balanced magnets. The compact body measures 27.7 × 27.7 × 26mm, with a listed motor weight of 50g. These characteristics make it suitable for installations where motor dimensions, mounting arrangement and propulsion-system weight are important design considerations.
This product is the clockwise (CW) rotation version. A set of socket-head cap (Allen) bolts is included for motor fitting, while the propeller adapter is excluded. The adapter must be purchased separately and matched to the motor shaft and selected propeller.
Motor Configuration & Electromagnetic Design
The motor uses a 12N14P configuration, identifying a 12-slot stator and 14-pole rotor arrangement. Its 920KV rating describes the motor’s nominal rotational speed constant in RPM per volt under no-load reference conditions. Actual operating speed varies with supply voltage, propeller loading and operating conditions.
- 12N14P Framework: Uses a 12-slot, 14-pole motor configuration.
- 14-Pole Rotor: The source explicitly identifies 14 poles in the motor assembly.
- 920KV Rating: Provides a nominal speed constant of 920 RPM per volt under no-load reference conditions.
- Balanced Magnets: The source identifies a balanced magnet assembly as a motor design feature.
- 180-Degree Magnet Feature: The source lists 180-degree magnets; the exact magnet geometry or measurement reference is not further defined.
- 450mA No-Load Current: Listed current consumption without the normal propeller load.
- 14A Maximum-Efficiency Current: Specified maximum-efficiency current value for motor performance reference.
Mechanical Construction & Bearing Assembly
The motor features a CNC-machined aluminium outer housing and Japanese EZO bearings. The aluminium construction provides the motor’s external mechanical enclosure, while the bearing assembly supports smooth shaft rotation. Its compact dimensions allow integration into suitable multirotor frames with compatible motor mounting provisions.
- CNC-Machined Aluminium Housing: Precision-machined aluminium outer construction.
- Japanese EZO Bearings: Bearing assembly identified for smooth motor operation.
- Compact Motor Body: 27.7mm length and width with a 26mm height.
- Lightweight Construction: Listed motor weight of 50g.
- Motor Mounting Hardware: A set of socket-head cap (Allen) bolts is included for fitting.
- Propeller Adapter Excluded: A separate compatible propeller adapter is required for propeller installation.
Electrical Compatibility & Propulsion Configuration
The motor is specified for 2S–4S LiPo battery configurations and has a listed maximum power rating of 220W. Battery selection, ESC capacity and propeller loading must be evaluated together. The 14A maximum-efficiency current value should not be interpreted as a confirmed maximum operating or continuous current rating.
- Battery Compatibility: Listed for compatible 2S, 3S and 4S LiPo systems.
- Maximum Power Rating: 220W as stated in the source specifications.
- No-Load Current: 450mA listed without propeller load.
- Maximum-Efficiency Current: 14A listed for the maximum-efficiency operating point.
- ESC Matching: Requires a compatible brushless ESC selected according to battery voltage, motor current demand and propeller load.
- Propeller Selection: Propeller diameter, pitch and loading should be matched to the motor’s electrical and mechanical operating limits.
Rotation Direction & Propeller Adapter Requirements
This model is the CW (clockwise) rotation version. Rotation direction must be considered when configuring a multirotor propulsion system, particularly when matching motors with the required propeller orientation. The propeller adapter is not included, so the correct adapter must be sourced separately.
- Motor Rotation: CW – clockwise version.
- Propeller Adapter: Not included in the package.
- Adapter Compatibility: Confirm shaft dimensions and adapter interface before purchasing a separate propeller adapter.
- Propeller Matching: Select a propeller compatible with the adapter, motor operating limits and intended aircraft configuration.

Installation & Operating Recommendations
- Verify Battery Configuration: Use a compatible 2S–4S LiPo system and confirm the selected battery voltage against the motor and ESC requirements.
- Match the ESC: Select a brushless ESC with suitable voltage and current capability for the actual propeller load. Do not use the 14A maximum-efficiency current as a confirmed maximum-current rating.
- Check Propeller Adapter Fitment: The adapter is not included. Confirm the motor shaft dimensions and adapter interface before ordering a replacement.
- Confirm CW Rotation: Install this motor in a position that requires clockwise rotation and match it with the correct propeller orientation.
- Verify Frame Mounting: Check motor mounting-hole spacing, screw length and frame clearance before installation; these details are not provided in the supplied specifications.
- Secure Mounting Bolts: Use the included Allen bolts with suitable mounting points and ensure that the screws do not interfere with internal motor components.
- Check Propeller Clearance: Ensure adequate clearance from the frame, wiring and adjacent propellers.
- Inspect Before Operation: Check the motor, bearings, mounting hardware and propeller adapter for looseness or mechanical damage.
- Perform a Controlled Test: Verify motor rotation and electrical operation at low throttle before proceeding to normal aircraft operation.
- Monitor Operating Conditions: Evaluate current draw and motor temperature with the selected propeller and battery configuration before extended operation.
