Bidirectional control is implemented for a motor to increase its operational degree. The motor can rotate in either direction with a current of 1A. A variable duty cycle multivibrator is utilized to achieve the construction and control of the motor's direction. The system includes a potentiometer that, when adjusted, alters the oscillation waveform symmetry. When the motor is halted, sliding the potentiometer to one side will cause the motor to rotate in the corresponding direction.
A schematic for a bidirectional motor control circuit typically includes several key components: a multivibrator circuit, a motor driver, and a potentiometer for user input. The multivibrator generates a pulse-width modulation (PWM) signal, which is essential for controlling the speed and direction of the motor. The duty cycle of this PWM signal can be varied by adjusting the potentiometer, allowing for fine-tuned control over the motor's operation.
The motor driver, often implemented using an H-bridge configuration, enables the motor to rotate in both directions. The H-bridge consists of four switches (transistors or MOSFETs) that can be activated in pairs to reverse the polarity of the voltage applied to the motor. This arrangement allows the motor to be driven forward or backward by changing the state of the switches based on the PWM signal from the multivibrator.
In the circuit, when the potentiometer is centered, the multivibrator produces a symmetrical waveform, resulting in no net movement of the motor. Adjusting the potentiometer to one side increases the duty cycle of the PWM signal, which in turn increases the average voltage supplied to the motor, causing it to rotate in one direction. Conversely, moving the potentiometer to the opposite side decreases the duty cycle, reversing the motor's rotation.
The inclusion of feedback mechanisms, such as limit switches or encoders, can enhance the functionality of this circuit by providing position feedback to the control system, allowing for precise control of the motor's movement. Overall, this bidirectional control circuit is a versatile solution for applications requiring adjustable motor speed and direction.
