This is an open-source low-cost BLDC driver boards in the form of a Arduino shield. It is a part of the *Simple**FOC*** project. The board is the big brother of the *Simple**FOC**Shield* and is designed to drive motors with higher current requirements, up to 30Amps. The board is created with the same philosophy as the *Simple**FOC**Shield* - to be simple to use, low-cost, and open-source and fully compatible with the *Simple**FOC***library. 

Additionally the aim of the board is to serve as a template project for the community to build their own motor drivers. 
- The board is relatively simple and can be easily modified to fit different requirements.

## Temperature characteristics

This board can measure the phase currents up to 30Amps, so it is intended to be used in applications that require current draw up to around 20Amps continuous. For higher currents especially in the range of 15-30Amps the board can get quite hot. Depending on the copper thickness of the PCB chosen when ordering the board the temperature can vary, as well as the cooling conditions. The board can be fitted with a heatsink to improve the thermal performance.

So I've wanted to quantify the temperature characteristics of the board when a continuous current is applied to the motor. The measurements were done with a relatively constant ambient temperature of around 25°C. The board was powered with 24V. The motor was run at very low speed (0.1rad/s) in the open loop and the current (q component) was set to 10, 15 and 20 amps for prolonged periods of time. I've measured the temperature on the top of the board on the DRV8320H gate driver and the BSZ0904NSI mosfets. I've used the PICOLOG TC-08 thermocouple data logger to do the measuring.

Two copper thicknesses were tested
1. Standard 4-layer: 
    - **1oz** (35um) copper thickness on top and bottom layers, 
    - **0.5oz** (17.5um) copper thickness on inner layers

<img src="images/experiment/1oz (1).jpg" height="200px"><img src="images/experiment/1oz (2).jpg" height="200px">

2. Thick 4-layer: 
    - **2oz** (70um) copper thickness on top and bottom layers, 
    - **0.5oz** (35um) copper thickness on inner layers

### Experiment results
Here is the table of the results

Current [A] | Standard 4-layer MOSFETS | Thick 4-layer  MOSFETS | Standard 4-layer DRV8320 |  Thick 4-layer DRV8320 
--- | --- | ---| --- | ---
10 | 57°C| 53°C | 50°C  | 52°C
15 | 78°C | 68°C| 62°C  | 62°C
20 | 125°C  | 100°C | 82°C | 82°C

So the results seem to suggest that, as the **BSZ0904NSI** mosfets are rated for temperatures up to 150°C and the **DRV8320H** gate driver up to 125°C, the board can be used up to 20Amps without additional cooling. 

**However, I would definitely recommend using a heatsink or a thicker copper PCB (2oz top and bottom layers) for currents above 15Amps continuous.**
