DRV8305: Need suggestion for off the shelf Driver Kit + BLDC for large current operation

Anuraag Mohan18

Part Number: DRV8305

HI,

I am working on a hands-on demo showing the current waveforms in BLDC operation and need an off the shelf solution for this. I am looking for a motor driver eval kit + a BLDC motor. The BLDC should be carrying currents as large as 10-20A so that I can pick it up and display easily with current probes.

I came across the following reference design that works with the Electrocraft (RP34-313V24-100) motor.

However, this design PCB needs to be fabbed and assembled. Is there a suitable recommendation for an already built and assembled demo kit that can meet my requirements.

Thanks

Hi Anuraag,

Would this work: www.ti.com/.../DRV8305-Q1EVM ?

Thank you. This looks great. So can I just get a BLDC motor in the following link with operating voltage < 45VDC and max continuous current < 25A and plug it with this board.

Alternatively, can you share the motor details shown in Fig. 17 of the 830Q1 Eval Module User's guide (link below):

Hi Anuraag,

Yes, you should be able to use the motor you selected. Please note the motor you selected has a large stall current. It is important to limit the current during stall. This can be done using the VDS setting in the SPI registers.
