DDSM400 Technical Specifications
El DDSM400 engine It is a model designed to offer excellent performance in applications that require precision y control. It stands out for its architecture direct transmission (Direct Drive), eliminating the need for reducers and offering a efficiency close to 100%.
- Adjustable speed: Operates from 100 RPM (rated torque) to 400 RPM (no load).
- IP54 Protection: This degree of protection makes it resistant to dust and splashes.
- All-in-one integration: Combines PMSM, encoder and servo in one compact body.
- LIN Communication: It allows simultaneous control of multiple motors and access to real-time data such as position, speed and temperature.
As a result, the DDSM400 is ideal for mobile robots, autonomous guided vehicles and other systems that demand precision.
Wired control and JSON
One of the most notable advantages of the DDSM Driver HAT (B) is its ability to receive and send commands in the format JSON. This format simplifies communication between the controller and the host device. Using a simple USB-C cable, you can use debugging software or Python scripts to control your engines.
Example JSON command to change the engine ID:
{"T":10011,"id":1}
In addition, it is possible to obtain real-time information such as engine position, speed o temperature, making the debugging and tuning process much more convenient.
Wireless control with ESP32
If you prefer not to use cables, the ESP32 integrated into the board offers a solution versatile via WiFi. Once powered, the board automatically establishes a Hotspot accessible from any mobile device, tablet or PC.
The web application allows:
- Send JSON commands directly to the controller.
- Monitor data in real time.
- Setting parameters such as engine ID or operating mode.
This is particularly useful for projects that require quick settings in the countryside.
Engine operating modes and configuration
The DDSM400 supports several operating modes that can be adjusted according to the needs of the project:
- Open loop mode: Similar to PWM control in DC motors.
- Current loop mode: Controls the current level for precision adjustments.
- Speed loop mode: Designed to maintain stable speeds.
- Position loop mode: Ideal for precise movements where a absolute control.
These modes are configured via JSON commands. For example, the command to enable the engine uses the following format:
{"T":11002,"id":1}
To switch between modes, simply modify the value of the "mode" parameter within the corresponding command.
Raspberry Pi integration
The DDSM Driver HAT (B) was designed to integrate easily with Raspberry Pi boards. The controller can be powered directly from the same power supply as the Raspberry Pi, simplifying cable and connection management. This is especially advantageous for projects where the space and order are essential, such as on mobile platforms and small robots.
The DDSM Driver HAT (B) and DDSM400 motor are essential tools for any robotics or automation project that requires high precision and flexibility. Thanks to their innovative design, support for multiple communication protocols, and ease of configuration, these devices stand out as a reliable solution for a wide range of applications. If you are looking to optimize your controlled motion projects, this combination is the perfect choice.
