Coreless Motor and Propeller (8x20mm) (Pack of 4)
Coreless Motor and Propeller (8x20mm) (Pack of 4)
The Coreless Motor and Propeller (8x20mm) is a compact and efficient motor system designed for use in small-scale unmanned aerial vehicles (UAVs), robotics, and other IoT applications. This pack of 4 includes four individual motor and propeller units, each consisting of a coreless motor and a closely matched propeller. The system is optimized for high performance, low power consumption, and reliability.
The Coreless Motor and Propeller system is designed to provide efficient and reliable propulsion for small-scale UAVs, drones, and other IoT devices. The coreless motor uses a unique design that eliminates the traditional iron core, resulting in a lighter and more efficient motor. The motor is paired with a carefully matched propeller, which is designed to optimize airflow and thrust.

Coreless Motor and Propeller (8x20mm) DocumentationOverviewThe Coreless Motor and Propeller (8x20mm) is a compact and lightweight motor designed for small-scale applications, particularly in robotics, drones, and IoT projects. This pack of four motors comes with propellers, making it an ideal solution for quadcopters, hexacopters, and other multi-rotor systems.Key SpecificationsMotor Size: 8mm x 20mm
Propeller Size: 8mm x 20mm
Voltage: 3-6V
Current: 0.5-1.5A
Speed: 12000-18000 RPM
Torque: 0.5-1.5 gf.cm
Bearings: Coreless design, low friction
Weight: 2.5g (motor only), 5g (motor with propeller)Connectivity and ControlThe motor can be controlled using a PWM (Pulse Width Modulation) signal, allowing for precise speed control. The motor wires are typically connected to a microcontroller or a dedicated motor driver IC.Code Examples### Example 1: Basic PWM Control using ArduinoThis example demonstrates how to control the motor speed using an Arduino board and the built-in `analogWrite()` function.```c++
const int motorPin = 9; // Pin 9 for motor controlvoid setup() {
pinMode(motorPin, OUTPUT);
}void loop() {
// Set motor speed to 50% (medium speed)
analogWrite(motorPin, 128);
delay(1000);// Set motor speed to 25% (low speed)
analogWrite(motorPin, 64);
delay(1000);// Set motor speed to 75% (high speed)
analogWrite(motorPin, 192);
delay(1000);// Turn off the motor
analogWrite(motorPin, 0);
delay(1000);
}
```### Example 2: Quadcopter Control using ESP32 and PWMThis example demonstrates how to control four Coreless Motors and Propellers using an ESP32 board and the `ledc` library for PWM control.```c++
#include <WiFi.h>
#include <esp32_pwm.h>// Define motor pins
const int motor1Pin = 18;
const int motor2Pin = 19;
const int motor3Pin = 21;
const int motor4Pin = 22;void setup() {
// Initialize motor pins as outputs
pinMode(motor1Pin, OUTPUT);
pinMode(motor2Pin, OUTPUT);
pinMode(motor3Pin, OUTPUT);
pinMode(motor4Pin, OUTPUT);// Initialize PWM channels
ledcSetup(0, 50, 16); // Channel 0, freq 50Hz, 16-bit resolution
ledcSetup(1, 50, 16);
ledcSetup(2, 50, 16);
ledcSetup(3, 50, 16);// Attach motor pins to PWM channels
ledcAttachPin(motor1Pin, 0);
ledcAttachPin(motor2Pin, 1);
ledcAttachPin(motor3Pin, 2);
ledcAttachPin(motor4Pin, 3);
}void loop() {
// Set motor speeds to stabilize the quadcopter
ledcWrite(0, 128); // Motor 1: 50% speed
ledcWrite(1, 128); // Motor 2: 50% speed
ledcWrite(2, 128); // Motor 3: 50% speed
ledcWrite(3, 128); // Motor 4: 50% speeddelay(100);
}
