Evaluation and Demonstration Boards and Kits

Evaluation and demonstration boards and kits are a great way to evaluate and demonstrate the capabilities of standard electronic components. In particular, ATSAMD21BLDC24V-STK, or ATSAMD21 BLDC Motor Control kit, is a powerful and versatile tool for engineers and makers to evaluate and control BLDC motor. It operates on a 24V DC voltage, and contains several external components to control and monitor the performance of a BLDC motor.

Application Fields

The ATSAMD21BLDC24V-STK board offers several user-friendly functions for engineers to experiment with BLDC motors. Specifically, it can be used to control and monitor the BLDC motor current and temperature, set the BLDC motor frequency, acquire the motor\'s speed information, detect the over-current condition, etc. Its intuitive graphical user interface makes it easy for users to modify and debug their motor’s settings.

The ATSAMD21BLDC24V-STK board has a wide range of applications. It can be used for various applications including brushless DC motor control, direct current (DC) motor control, and low-frequency AC motor control. Other than that, since the board features drag-and-drop programming, it is easily programmable with Arduino\'s development environment. This makes the board suitable for a range of projects related to robotic systems, automation, intelligent control, etc.

Working Principle

The ATSAMD21BLDC24V-STK board controls the BLDC motor using an 8-bit Advanced Microcontroller Unit (AMU) and a set of external components. To start, the AMU produces a 3-phase electrical signal to the motor’s windings. This then creates an electrical field that turns the motor in a certain direction. Then, the AMU produces electrical pulses to the motor’s windings. These pulses quickly establish a new magnetic field, and the motor rotates in its new direction. As the motor is running, the user may adjust the pulse frequency by setting different duty cycles. The overall effect is a controlled and variable speed BLDC motor.

The ATSAMD21BLDC24V-STK board also uses several external components to monitor the performance of the motor. This includes a set of current sensing components that measure the current taken by the motor. The board also uses a set of thermistors to measure the motor\'s temperature. Additionally, the board contains a Quadrature Decoder Logic (QDL) circuit which calculates the speed of the motor by sensing the frequency of the pulses. This helps the user to also monitor the motor’s speed.

The ATSAMD21BLDC24V-STK board also has a low-leveled driver circuit which is connected to the system’s MCU. This driver circuit helps to in detecting over-current condition and activates a protection circuit which shut off the power supply to the motor. Thus, it helps to prevent the motor from getting damaged.

Conclusion

Overall, the ATSAMD21BLDC24V-STK board is a great tool for creating robust motor control designs. Its intuitive graphical user interface allows users to easily modify and debug the motor’s settings. Additionally, the board includes several external components to measure the performance of the BLDC motor. Its wide range of applications makes it suitable for a range of projects related to robotic systems, automation, intelligent control, etc. In summary, the ATSAMD21BLDC24V-STK board is a great tool for evaluation and demonstration of standard motor control components.
