The MRB Planetary Gearbox Motor typically has two terminals for electrical connections. These are:
Pin Name | Description |
---|---|
V+ | Positive terminal for power input |
V- | Negative terminal for power input (ground) |
For models with an encoder, additional pins may be present:
Pin Name | Description |
---|---|
A | Encoder output channel A |
B | Encoder output channel B |
Vcc | Power supply for the encoder (e.g., 5V) |
GND | Ground for the encoder |
Below is an example of how to control the MRB Planetary Gearbox Motor with an Arduino UNO using a motor driver (e.g., L298N):
// Example code to control MRB Planetary Gearbox Motor with Arduino UNO
// Motor driver connections:
// IN1 -> Pin 9, IN2 -> Pin 10, ENA -> Pin 3 (PWM)
#define IN1 9 // Motor driver input 1
#define IN2 10 // Motor driver input 2
#define ENA 3 // Motor driver enable pin (PWM)
void setup() {
pinMode(IN1, OUTPUT); // Set IN1 as output
pinMode(IN2, OUTPUT); // Set IN2 as output
pinMode(ENA, OUTPUT); // Set ENA as output
}
void loop() {
// Rotate motor forward
digitalWrite(IN1, HIGH); // Set IN1 high
digitalWrite(IN2, LOW); // Set IN2 low
analogWrite(ENA, 128); // Set speed (0-255)
delay(2000); // Run for 2 seconds
// Rotate motor backward
digitalWrite(IN1, LOW); // Set IN1 low
digitalWrite(IN2, HIGH); // Set IN2 high
analogWrite(ENA, 128); // Set speed (0-255)
delay(2000); // Run for 2 seconds
// Stop motor
digitalWrite(IN1, LOW); // Set IN1 low
digitalWrite(IN2, LOW); // Set IN2 low
analogWrite(ENA, 0); // Set speed to 0
delay(2000); // Wait for 2 seconds
}

Q: Can the MRB Planetary Gearbox Motor be used with a battery?
A: Yes, the motor can be powered by a DC battery, provided the voltage and current ratings match the motor's requirements.
Q: How do I select the right gear ratio?
A: Choose a gear ratio based on the required torque and speed for your application. Higher gear ratios provide more torque but reduce speed.
Q: Can I use the motor without an encoder?
A: Yes, the motor can operate without an encoder, but you will lose speed and position feedback.
Q: What is the lifespan of the gearbox?
A: The lifespan depends on operating conditions, load, and maintenance. Proper alignment and avoiding excessive loads can extend its life.
