Test the circuit. The DC motor should now be spinning if all components are securely connected. Rotating or adjusting the potentiometer should change the speed of the motor with either limit being the motors fastest speed, and the slowest speed the potentiometer can provide. If the motor is not running, check all the connections to make sure the circuit is securely connected. If the motor still doesn't run, check that the battery is not dead by connecting it directly to the motor and replace or recharge if dead.
In this method, the field winding is excited by a constant voltage but the armature winding is supplied with different voltages through switching devices. The speed of the motor will be proportional to the armature voltage.
*Avoid using high voltages and currents as this can damage the components and be dangerous to work with.*
Finally connect the source pin of the mosfet to the other pin of the dc motor. Now just plug in the 9V battery and we are done.
Initialize the BUTTON & DC_MOTOR in the main application, start the DC Motor, read an analog potentiometer with ADC. And use that reading to control the motor speed in the main loop of the system. Read the buttons and use it to flip the direction of motor rotation. Repeat!
Therefore, the MOSFET we select must support a gate input voltage of 5V to provide a maximum output within its limit.
We can use an H-Bridge circuit to do this. The H-Bridge circuit derives its name from the four transistors that look like an “H.
Once the entire resistance is removed, the full line voltage is connected across the motors, hence the motor runs at a higher speed.
Prepare the power supply. If using a power pack, install the batteries so the + and - sides are facing the correct directions in the housing. If it can be done, keep the power supply off for now.
A DC motor has some significant advantages, and one of them is the simplicity of its control system. Here, we’ll tell you how a DC motor controller works and how you can use it.
We’ll have to do this step just to have the TIM_HAL files added to our project by CubeMX. And also it gives us a startup configuration for the PWM channel of that specific timer module as we’ll see hereafter. This is the best way to keep the code generic and portable to any STM32 microcontroller.
In a DC series motor, the flux can be varied in different ways like diverting the field current, tapping the field current at different points in the field winding and paralleling the field coils. Let us discuss them in detail.
However, in case the PWM frequency is too high, the MCU may have problems with generating PWM signals of the required value. In addition, the very high frequency may lead to the malfunction of the gate driver and transistor switches as they may not be compatible with it.
After inserting the components we need to create the board outline and start arranging the components. The two capacitors should be placed as near as possible to the 555 Timer, while the other components can be placed wherever we want, but still in a logical arrangement according to the circuit schematic.
