The TMC223-EVAL is an evaluation board demonstrating the capabilities and features of Trinamic's TMC 223 two-phase stepper motor controller. Through its position mode, the TMC 223 offers closed-loop operation with optimal smoothness and precise positioning of the motors. It also offers microstepping and adjustable speed profiles.

The TMC223-EVAL is equipped with multiple connectors to interact with a number of other components. Connectors on the board include USB, CAN, and I2C, as well as 3-pin motor outputs for connection to stepper motors. The board also includes various adjustable components, such as a potentiometer for setting the current level and a voltage regulator for setting the motor supply voltage.

Application Field of TMC223-EVAL:

TMC223-EVAL evaluation board is optimized for applications in industry, automation, laboratory equipment, medical devices and robotics. In particular, it is suited for speed and position- calibrated stepper motor control, such as in 3D printing technology.

Working Principle of TMC223-EVAL:

The TMC223-EVAL is based on Trinamic's TMC 223 two-phase stepper motor controller. The controller monitors the position of the motor in either absolute or relative coordinates, and then commands the motor to move in position-mode. This mode ensures smooth motion control and precise positioning of the motor.

The TMC223-EVAL board also offers microstepping, meaning the motor can be moved in smaller steps than the controller's native resolution. This is useful for applications such as 3D printing, or for better motor accuracy in smooth controlling applications. In addition, the board comes with adjustable speed profiles, enabling control of the speed of each motor.

The TMC223-EVAL includes an on-board circuit board and software for controlling the motors from a personal computer. The PC software allows users to configure the controller's parameters, including acceleration, speed, and position mode.

Conclusion:

The TMC223-EVAL evaluation board is designed to demonstrate the capabilities of Trinamic's TMC 223 two-phase stepper motor controller. It is offered with various adjustable components, such as a potentiometer for setting the current level and a voltage regulator for setting the motor supply voltage. With its position mode, the TMC 223 offers closed-loop operation with optimal smoothness and precise positioning of the motors. In addition, the board comes with microstepping and adjustable speed profiles. Its application field includes industry, automation, laboratory equipment, medical devices and robotics.
