Evaluation and Demonstration boards and kits have become a common tool to help the development of applications and systems. The STEVAL-IHM021V1 kit is an example of such a tool, used to quickly gain a working understanding of the three-phase brushless DC motor drive functionalities. This kit enables users to focus on building their application while they have all the required elements in the same board.

Overview

The STEVAL-IHM021V1 kit is a three-phase motor driver evaluation and demonstration kit, based on the STSPIN32F0A device which is part of the STSPIN32F0A family. It incorporates both the STSPIN32F0A, used as the analog motor control device, and an STM32F0 microcontroller, used as the digital controller. Both devices are located on the same PCB, together with all the necessary components to make the entire system work.

Features

The STEVAL-IHM021V1 kit offers the following features:

• It is fully optimized to work with U-ISA3V3, the STMCube development environment in order to work with the STSPIN32F0A analog motor driver.
• It allows easy measurement in real time via the PC GUI when connected to the PC through USB.
• It includes all the necessary components for the operation such as the motor, sensors, capacitors and diodes.
• It is compliant with safety requirements, including thermal protection and demagnetizing protection.

Application fields

Using the STEVAL-IHM021V1 kit, it is possible to develop applications, evaluation and demonstration projects. These include a complete motor drive package for near- and mid-field applications, including:

• Sensorless Field Oriented Control (FOC) motor drives
• Field Oriented Control drives with different sensors
• Control of brushless DC motors with sensor feedback
• Control of 3-phase induction motors with sensor feedback

Working principle

The STEVAL-IHM021V1 kit works by connecting the STSPIN32F0A device to an external power supply and the STM32F0 microcontroller to the PC. The STM32F0 microcontroller then sends the necessary commands and data to the STSPIN32F0A device via a serial communication interface. The STSPIN32F0A device then processes the data and applies the appropriate voltage and current to the motor, thus driving it.

The complete system includes a 3-phase brushless DC motor, Hall effect sensors, current and voltage sensing boards, and capacitors, all of which are necessary for the operation of the demo and evaluation board. The 3-phase motor is connected to the electronic boards, while the Hall effect sensors are sensing information about the rotor position and its speed. The current and voltage sensing boards are used for monitoring the voltage and current applied to the motor, while the capacitors are used for buffering.

Conclusion

The STEVAL-IHM021V1 kit offers a cost-effective solution for development and demonstration of 3-phase motor drives. It enables users to quickly understand and evaluate the functionalities of a three-phase brushless motor drive and its associated components, such as Hall effect sensors, current and voltage sensing boards, and capacitors. Additionally, the kit includes a simple user interface which allows easy real-time measurements to be made. This kit is therefore an ideal choice for development and evaluation projects in near- and mid-field applications.
