Hello all,
I am looking to build a BLDC motor controller or modify one. The NXP reference boards are insufficient with the power stage current. The motor I have is 3 phase and intended for operation in roughly the 12 to 14 V dc range. The motor power rating is somewhere around 1.2 KW and I think the stall current is around 150 Amps. I am not sure what the average operating current is. Also, I think the design was for operation up to around 4,000 RPM and the motor design is 12 slots with 8 poles.
Any thoughts about using a NXP reference design and modifying the Power Output Stage to handle the motor I have?
I have the S12ZVML MINI-BRD Development Board for 3-phase sensorless BLDC and I have the S32k144 Eval board.
Here are my questions:
Should I try to modify the power stage of the S12ZVML-MINIBRD to drive my motor or should I look at the S32K144 Eval board since I need to modify the power stage anyway or should I do a design from scratch?
If I try to modify the S12ZVML-MINIBRD power stage, what changes need to be made for the sensorless feedback?
Thanks,
David
