Controlling DC Motor with BTS7960 ESC

Controlling Speed and Direction of DC Motor using BTS7960 and 20 Ampere Brush ESC

In this tutorial, we will explore how to control the speed and direction of a DC motor using a BTS7960 driver and a 20 ampere brush Electronic Speed Controller (ESC). This setup is commonly used in robotics and other applications where precise control over the motor's speed and direction is required.

Components Needed

• DC Motor
• BTS7960 Driver
• 20 Ampere Brush ESC
• Buck Module (for voltage regulation)
• XT60 Connector (for connecting battery to BTS7960)

Step-by-Step Instructions

First, connect the both enable pins of the BTS7960 driver to VCC. This will allow us to control the motor's speed and direction.

Next, connect an XT60 connector to the battery terminal of the BTS7960 driver. This will provide power to the driver.

Now, connect a buck converter in parallel with the plus and minus terminals of the BTS7960 driver. This will regulate the voltage output to the motor.

Connect the battery to the system and set the output of the buck module to 5 volts.

Now, connect the out minus terminal of the buck module to the ground terminal of the BTS7960 driver. Connect the out plus terminal of the buck module to the VCC terminal of the BTS7960 driver.

Cut off the connector from the ESC (Electronic Speed Controller). This will allow us to connect the motor terminals directly to the BTS7960 driver.

Refer to the pin diagram of the ESC and connect the battery terminal of the ESC to VCC. Connect the ground terminal of the BTS7960 driver to the ground terminal of the ESC.

Now, connect the motor terminals of the ESC to the PWM (Pulse Width Modulation) and LPWM (Low Pulse Width Modulation) pins of the BTS7960 driver. This will allow us to control the speed and direction of the motor.

Connect the motor terminals of the BTS7960 driver to the motor terminal of the ESC.

Finally, connect the signal pin of the ESC to channel 1 of the receiver. This will allow us to control the speed and direction of the motor using a joystick or other controller.

Testing the System

Connect the battery to the system and turn on the transmitter. Check that both the speed and direction of the motor can be controlled by the joystick or other controller.

Congratulations! You have now successfully set up a BTS7960 driver and 20 ampere brush ESC to control the speed and direction of a DC motor.

• Muscle activation and relaxation
• Motor unit recruitment and firing patterns
• Sensory-motor integration and feedback loops
• Cognitive influences on motor performance, such as attention and learning

• Equilibrium-point hypothesis: proposes that movement is controlled by setting the equilibrium point of the muscle-tendon system.
• Servo-control theory: suggests that motor control involves a continuous feedback loop between sensory input and motor output.
• Dynamical systems approach: views motor control as an emergent property of complex, nonlinear interactions within the nervous system.

Introduction

Understanding the BTS7960 ESC

Key Features:

• High-power handling capability
• PWM technology for smooth speed control
• Supports DC motors up to 100A continuous current
• Wide input voltage range (6-24V)
• Compact design with a small footprint

Connecting the BTS7960 ESC to a DC Motor

• Motor wires: Connect the DC motor's positive and negative terminals to the ESC's motor output terminals.
• Power supply: Connect the power supply (e.g., battery) to the ESC's input terminals.
• Control signal: Connect the control signal wire (usually a PWM signal) from your microcontroller or other control device to the ESC's control input terminal.

Configuring the BTS7960 ESC

• Motor type: Select the type of DC motor being used (e.g., brushed, brushless).
• PWM frequency: Set the PWM frequency for smooth speed control.
• Deadband: Adjust the deadband setting to minimize motor vibration.

Controlling the DC Motor

Example Code:

// Arduino example code
const int pwmPin = 9; // PWM output pin

void setup() {
  pinMode(pwmPin, OUTPUT);
}

void loop() {
  // Set motor speed to 50%
  analogWrite(pwmPin, 128); // 128 is the midpoint of 0-255 (50% duty cycle)
  delay(1000);

  // Set motor speed to 100%
  analogWrite(pwmPin, 255);
  delay(1000);
}
