TMC2224-EVAL-KIT is an evaluation and demonstration board or kit designed to take advantage of STmicroelectronics’ microstepping motor and driver chipsets. It uses the TMC2224 chipset, a four-phase bipolar stepper motor and a DC power supply to control three-phase motors with a rated power up to 5A. The main components of TMC2224-EVAL-KIT are TMC2224 microstepping driver, a two-phase bipolar parallel stepper motor, a host computer with graphical user interface (GUI), and a DC power supply.

The TMC2224-EVAL-KIT offers various features and functions which include temperature protection, current and torque control, microstepping capability, standstill detection for synchronization, and more. It supports micro-stepping from full step to quarter-step, and the current can be set from 0.4 A to 5 A. Its standstill detection feature is useful for synchronization between various devices.The TMC2224-EVAL-KIT also offers an optional host computer with a graphical user interface (GUI) for monitoring and controlling the TMC2224-EVAL-KIT, also allowing step/dir signals and frequency-mode operation. The host computer can be connected through a USB or serial port.

The working principle of the TMC2224-EVAL-KIT is based on the axiom of torque versus current control. Using a two-phase bipolar parallel stepper motor, the board senses direction and angle information from the motor through embedded encoders. This information is analyzed by the board’s internal software and the current is then adjusted accordingly. This allows for more precise and efficient control of the motor’s torque. The board also sends data back to the host computer, ensuring the board is consistently monitoring and controlling the motor.

TMC2224-EVAL-KIT is a versatile product and can be used for a wide range of applications such as industrial automation, robotic control, and medical equipment, as well as being an easy-to-use platform for driver evaluation. By offering microstepping capability, standstill detection, and current and torque control, the TMC2224-EVAL-KIT is an ideal tool for anyone looking to evaluate and optimize their motor’s performance.
