SPIDER Automation | 615 Magnetic Micro Coreless Motor & 55mm Propeller Combo | 3.7V Brushed Micro Quadcopters
Description
The SPIDER Automation 615 Magnetic Micro Coreless Motor and 55mm Propeller Combo Set is a miniature brushed DC propulsion package for compact multirotors, indoor micro quadcopters and lightweight aircraft platforms. The 615 motor uses a magnetic coreless construction with a high-speed, low-torque operating profile. It is specified for a 3.7V DC rated supply and a 1S single-cell battery configuration.
Each motor has a compact 6mm diameter and 15mm body length, with a 1mm output shaft. The supplied specifications list motor speeds of 41,000 RPM and 60,000 RPM, along with a rated load current of 580mA. These values should be considered alongside propeller loading, battery capability and the electrical limits of the brushed motor driver when configuring the propulsion system.
The package includes four motors in a balanced rotation arrangement—two clockwise (CW) and two counter-clockwise (CCW)—plus two 55mm plastic propeller blades in red and black. Motor direction is identified by wire colour: red and blue wires for CW rotation, and black and white wires for CCW rotation. The supplied propellers are specified for 615, 720 and 8520 coreless motors.
Key Features
- Magnetic Coreless Motor Construction: Miniature brushed DC motor design intended for compact, lightweight propulsion applications.
- High Rotational Speed: Listed motor speed ratings include 41,000 RPM and 60,000 RPM.
- 1S Battery Operation: Designed for a 3.7V single-cell battery supply.
- High-Speed, Low-Torque Profile: Intended for small propeller-based propulsion systems where motor and propeller matching is important.
- Low-Noise Operation: The motor is described as supporting comparatively quieter operation.
- Low-Resistance Design: Specified as a low-resistance motor configuration.
- Four-Motor Rotation Set: Includes two CW and two CCW motors for a four-motor multirotor layout.
- Colour-Coded Motor Wiring: Red/blue wire combination identifies CW rotation, while black/white identifies CCW rotation.
- 55mm Propeller Blades: Supplied blades are specified for 615, 720 and 8520 coreless motors.
- Compact Mechanical Dimensions: 6mm motor diameter, 15mm body length and 1mm shaft diameter.
Motor Rotation & Wiring Identification
The four motors are supplied in two rotation directions to support a conventional four-motor multirotor configuration. The supplied wire-colour identification is:
- Clockwise (CW) Motor: Red and blue wires.
- Counter-Clockwise (CCW) Motor: Black and white wires.
Use the rotation identification when assigning motors to the corresponding positions on the flight-control system. Confirm the actual direction of rotation during a low-power motor test before installing the propellers. Do not rely on wire colours alone if the motor wiring has been modified or replaced.
55mm Propeller Design & Compatibility
The supplied 55mm (approximately 2.2-inch) propeller blades are made from plastic and feature a smooth surface intended to reduce aerodynamic surface resistance during rotation. The source describes the material as high-tenacity, with impact-resistant characteristics for normal operating use.
The propellers are specified for compatibility with 615, 720 and 8520 coreless motors. The set includes one red blade and one black blade. The exact blade rotation markings and hub bore dimensions are not provided, so verify the fit and correct blade orientation before operation.

Connection & Operating Recommendations
- Supply Voltage: Use a compatible 3.7V single-cell battery system. Do not exceed the motor’s rated voltage without verified electrical specifications.
- Motor Driver Selection: Use a brushed motor driver or flight controller with outputs suitable for the motor voltage and current requirements.
- Rotation Identification: Identify CW motors by their red and blue wires and CCW motors by their black and white wires, as specified for this set.
- Propeller Installation: Confirm the propeller hub fits the 1mm motor shaft securely before operation.
- Blade Orientation: Confirm the correct propeller orientation for each motor position. The red and black colours alone do not establish CW or CCW blade direction.
- Current Verification: Check actual current draw under propeller load and ensure the battery, wiring and motor driver can support the required current.
- Initial Motor Testing: Test motor rotation and response with propellers removed before completing the multirotor assembly.
- Mechanical Inspection: Check shaft alignment, motor mounting and propeller condition before operation.
- Temperature Limits: Keep operation within the specified -20°C to 60°C temperature range.
- Propeller Safety: Keep hands and loose objects clear of rotating blades during testing and operation.
