Working Principle

The TMCM-1270-CANOPEN motor driver board employs a closed-loop h-bridge driver architecture, which is optimized to provide a variable speed control mode. The h-bridge driverICs are connected to the motor through a corresponding phase of a three-phase motor, the so-called \'h-bridge power stage\'.

The board also consists of a CANopen controller, which communicates with the higher-level controlling device over the CANopen bus. The CANopen controller is responsible for setting the parameters and running the motor, which are both done independently. Furthermore, the CANopen controller is responsible for issuing the ‘Enable’ command to the h-bridge driver. This command turns the motor on and off.

The motor driver board is also equipped with a temperature sensor, which is used to detect the temperature of the motor and prevent any overheating. Furthermore, the board also includes a voltage and current sensing circuitry, which provides the control system with feedback of the actual motor current.

Conclusion

The TMCM-1270-CANOPEN motor driver board is a compact and high-performance controller designed for controlling DC and Brushless DC motors. Featuring an integrated CANopen bus and a range of features, the driver board is suitable for a wide variety of industrial and consumer applications.
