The STEVAL-IHM032V1 evaluation board (STEVAL-IHM032V1) is an advanced three-phase motor control kit developed by STMicroelectronics. The design of the STEVAL-IHM032V1 is suitable for the control of small fractional horsepower permanent magnet synchronous (PMSM) or brushless DC (BLDC) motors. This advanced design can be used to enable users with high efficiency, low system cost, and smaller size motors, all with minimal development efforts.

The STEVAL-IHM032V1 is an open and powerful solution for Motor Control applications such as Variable Speed Fan, Small Water Pump, Home Appliance such as Vacuum Cleaners, Home Appliance Conversion, Home & Building Motors, HVAC control systems, Toggle Motor Control, and few Industrial Automation & Robotics. Its advanced power stage, high-performance protection circuitry, and flexible I/O, helps developers to build better motor controllers and also reduce development time.

The STEVAL-IHM032V1 provides a wide range of integrated features which includes three-phase motor power stage, an SML motor current sensor, a STM32F303 microcontroller, and a very low-cost board. Also the board provides an additional microcontroller for the micro-controller interfacing, which is dedicated to interface control commands.

The STEVAL-IHM032V1 board supports both sensorless and sensor-based PMSM algorithms such as Field Oriented Control (FOC) and Vector Control methods. The board also supports a range of motor control applications including speed control, torque control, current control, position control, and multiple motor control. The board has a rich set of features and peripherals, including an external EEPROM for custom data storage, USB and CAN interface, and a six-channel low-saturation comparator ideal for overcurrent sensing.

The STEVAL-IHM032V1 also supports the most advanced STM32Cube Motor Control software library - allowing developers to customize and optimize their motor control algorithms. Along with providing a wide range of features, the STEVAL-IHM032V1 comes with a range of important motor control development tools enabling quick initial design, rapid prototyping, and efficient system integration.

The working principle of the STEVAL-IHM032V1 is based on a three-phase operation with each phase energized with a fixed voltage level. The voltage levels in each phase is determined by the output control signals from the microcontroller. This way, the board can provide the required voltage levels to drive the motor. The board also features a built-in addressable motor control system based on the MCU, allowing designers to easily extend the motor control functions. The MCU can also be used to monitor the motor control parameters such as current, voltage, and temperature. The board also features protection circuitry which will prevent the motor from overcurrents or undervoltage.

The STEVAL-IHM032V1 is a very powerful and flexible solution for motor control applications with minimal development efforts. The comprehensive features, along with the wide range of development tools, allow users to easily customize the board and optimize algorithms performance. Its easy to use design and low cost makes it an ideal solution for home, building or industrial automation and robotics.
