⚠️ Rated voltage, RPM, shaft diameter, shaft length and current consumption may vary depending on stock batch. Please verify before precision replacement or engineering use.
How It Works / কীভাবে কাজ করে
The 717 motor is a simple two-wire DC motor.
When DC voltage is applied:
• One polarity rotates the motor in one direction
• Reversing polarity rotates it in the opposite direction
Example:
Red → Positive (+)
Blue → Negative (−)
Reverse the wires if opposite rotation is required.
⚠️ Wire color may vary depending on stock batch.
Coreless Motor Advantage
Compared with conventional iron-core brushed motors, coreless motors are designed with a lightweight rotor structure.
Typical advantages include:
✅ Lightweight construction
✅ Fast acceleration
✅ Quick speed response
✅ Compact size
✅ Suitable for high-speed applications
✅ Good choice for small flying and mobile projects
This is why 717-style motors are commonly found in mini drones and compact RC devices.
Use with Propeller / Drone Project
For mini drone or propeller applications:
• Use a propeller that matches the motor shaft
• Keep the propeller balanced
• Avoid oversized propellers
• Use a suitable battery voltage
• Check motor temperature during operation
• Secure the motor firmly in the frame
Using an oversized propeller can increase motor current and cause overheating.
Motor Driver / Control Note
For simple ON/OFF operation, the motor can be powered from a suitable DC source within its rated voltage.
For microcontroller control, use an appropriate:
• MOSFET driver
• Transistor driver
• Small H-bridge motor driver
• Drone ESC/control board designed for brushed motors
⚠️ Do not connect the motor directly to an Arduino, ESP32 or other microcontroller GPIO pin.
Important Notes / গুরুত্বপূর্ণ নোট
⚠️ Confirm the required operating voltage before use.
⚠️ Do not exceed the motor’s rated voltage.
⚠️ High voltage may cause excessive RPM, heating or permanent motor damage.
⚠️ Motor current increases significantly when the shaft is blocked.
⚠️ Never keep the motor stalled for long periods.
⚠️ Do not bend the motor shaft.
⚠️ Check propeller bore size before installation.
⚠️ Shaft dimensions may vary slightly by stock batch.
⚠️ For drone replacement, match size, voltage, shaft and rotation requirements with the original motor.
⚠️ Product wire color and motor appearance may vary slightly depending on stock batch.
