Brushed Drone Motors

High-Performance Brushed Drone Motors for Student Science & DIY Projects in Bangladesh

Are you building a custom micro drone, a mini quadcopter, or a school science project? Finding the right motor is the most critical step to get your aerial setup off the ground. At Biggan Project (বিজ্ঞান প্রজেক্ট), we offer a comprehensive selection of high-efficiency brushed drone motors tailored specifically for students, hobbyists, and DIY electronics enthusiasts across Bangladesh.

Brushed coreless motors remain the top choice for micro drones and beginner-friendly robotics because of their simple wiring, light weight, high RPM output, and cost-effective price point. Unlike complex brushless motors that require individual Electronic Speed Controllers (ESCs), brushed motors can be driven directly using simple transistor circuits, motor driver ICs, or popular microcontroller platforms like Arduino, ESP32, and STM32.

Whether you need compact 615 motors for indoor micro drones, 720 models for balanced thrust and payload, or powerful 8520 coreless motors for mini quadcopters, Biggan Project provides reliable, pre-tested components to ensure your project flies smoothly without unexpected power loss.

Why Choose Brushed Motors for Your DIY Drone Project?

• Plug-and-Play Simplicity: Requires simple two-wire DC connections (Positive and Negative), eliminating the need for complex multi-phase ESC calibration.
• High Thrust-to-Weight Ratio: Lightweight coreless designs deliver impressive RPM to lift 3D-printed frames, lightweight cardboard chassis, and mini sensors.
• Budget-Friendly for Students: Ideal for academic demonstrations, science fairs, and school competitions where cost efficiency is essential.
• Easy Speed Control: Seamlessly adjust motor speed using Pulse Width Modulation (PWM) from any microcontroller development board.

Selecting the Right Motor Size and Specification

Understanding motor dimensions is key to choosing the right power output for your drone frame:

• 615 Coreless Motor (6mm x 15mm): Best suited for ultra-light indoor micro drones, nano quadcopters, and miniature fan projects.
• 716 / 720 Coreless Motor (7mm x 16mm / 20mm): Offers an ideal balance of speed and lift force for medium-sized school science projects.
• 8520 Coreless Motor (8.5mm x 20mm): Delivers maximum thrust among micro brushed motors, perfect for carrying small wireless cameras, sensor payloads, or heavier frames.

Clockwise (CW) vs. Counter-Clockwise (CCW) Motors

Quadcopters require balanced rotational forces to maintain stability. Standard brushed drone motors come color-coded to indicate direction:

• CW (Clockwise): Typically features red and blue lead wires.
• CCW (Counter-Clockwise): Typically features black and white lead wires.

At Biggan Project (বিজ্ঞান প্রজেক্ট), we supply paired CW and CCW motor sets along with compatible matched propellers to help Bangladeshi students complete their quadcopter builds without directional mismatch errors.

Frequently Asked Questions (FAQ)

Can I control a brushed drone motor directly using an Arduino?

While an Arduino GPIO pin generates the PWM control signal, it cannot supply the high current required by the motor. You should drive the motor through a NPN transistor (like the 2N2222 or TIP120), a MOSFET (like the IRFZ44N), or a dedicated motor driver module (such as the L298N or DRV8833).

What voltage supply is recommended for micro brushed motors?

Most coreless drone motors operate within a 3.7V to 4.2V range, making them perfectly suited for single-cell (1S) Lithium Polymer (LiPo) or Li-ion batteries.

Where can I buy original drone brushed motors in Bangladesh?

You can order genuine, tested coreless drone motors online directly from Biggan Project (বিজ্ঞান প্রজেক্ট), with fast delivery across Dhaka, Chattogram, Rajshahi, Sylhet, and all regions of Bangladesh.
