Mini DC Motor and Propeller Set—Pink

Compact, robust, and easy to assemble, this set pairs a 1.5–3 V DC motor with a matching three-blade propeller. Ideal for STEM projects, DIY fans, airflow experiments, and small robotics prototypes, it runs directly from 1 or 2 AA batteries. Perfect for both electronics engineers and hobbyists integrating with Arduino, Raspberry Pi, and other microcontroller platforms.

Key Features ✨

• Ready-to-use set: Mini DC motor + matching three-blade propeller
• Operates from 1 or 2 AA batteries (approx. 1.5–3 V DC)
• Lightweight and impact-resistant propeller made of carbon-reinforced plastic
• Compact form factor for tight enclosures and educational builds
• Easy integration with Arduino and Raspberry Pi using common motor driver modules

Applications 🧪

• DIY fan and airflow demonstrations
• STEM learning kits and classroom projects
• Small robotics and prototyping with electronics components
• Basic motor control experiments (PWM speed control, voltage vs. RPM)

Specifications 🔧

• Propeller (Pink):
  Type: Three-blade
  Diameter: Ø8 cm
  Hub/Shaft diameter: Ø2 mm (fits motor shaft)
  Material: Carbon-reinforced plastic
  Attributes: Lightweight, impact-resistant
• DC Motor:
  Operating voltage: 1.5–3 V DC
  Body size: Length 28 mm, Width 20 mm
  Shaft diameter: Ø2 mm; Shaft length: 8 mm
  Speed: 8,000 RPM @ 1.5 V, 19,000 RPM @ 3 V
  Current draw: 20–300 mA @ 1.5 V, up to 900 mA @ 3 V

Electrical Performance ⚡

• Supply from 1 or 2 AA cells for safe, portable operation
• Observe correct polarity; reverse voltage changes rotation direction
• High startup/stall current possible (up to ~900 mA @ 3 V)—size your driver and power source accordingly

Microcontroller Integration 🔌

• Control via Arduino, Raspberry Pi, or other microcontroller platforms using a suitable motor driver module (e.g., TB6612FNG, L9110, L298N)
• Do not drive the motor directly from GPIO pins; use a driver and a separate battery supply where needed
• For single-transistor drives, include a flyback diode and use PWM for speed control

Package Contents 📦

• 1 × Three-blade propeller (Ø8 cm, Ø2 mm hub, carbon-reinforced, pink)
• 1 × 1.5–3 V DC motor (28 mm × 20 mm, Ø2 mm shaft × 8 mm)

Notes & Safety ⚠️

• Do not exceed 3 V without appropriate testing and thermal considerations
• Keep fingers and loose items away from the spinning propeller
• Balance and secure the propeller firmly to the Ø2 mm shaft to minimize vibration

This compact motor–propeller kit is a great addition to your DIY electronics components toolbox and an excellent choice for teaching fundamentals of voltage, current, and microcontroller-based motor control.
