Can I start with a BLDC motor controller? Where can I find more info about these?
Regarding your question, I suggest you use KV family or DSC especially MC56F84xxx or MC56F827xx, they focus on the motor control and energy conversion.
This is the KV link:
Kinetis V Series: Real-time Motor Control & Power Conversion MCUs based on ARM Cortex-M0+/M4/M7|NXP
This is the DSC link:
Digital Signal Controllers|NXP
We have developed the motor control library for example PID, clark/park conversion, SVPWM...for both DSC and Cortex-M4/M0/M7
The KV58 has two eFlexPWM and FTM modules, which can generate multiple group PWM signals, can interface with hall, encoder, resolver sensors.
Hope it can help you
Hello XiangJun Rong,
Thanks for your mail.
These are choices I see in selecting the development board. Can you help me in solving queries for the same?
Is it possible to implement Sensorless FOC in the below development boards?
KEA128BLDCRD: 3-phase Sensorless BLDC Motor Control Reference Design Based on Kinetis KEA128 MCUs
Do you want to control a BLDC or PMSM? although the BLDC and PMSM are similar from structure, they use totally different methods to control.
I want to use a BLDC motor as I have some experience working with it and please let me the know the accessories such as motor and debugger.
As you know that the PMSM/ACIM uses FOC algorithms to control, if you use BLDC motor, it is simple to control.
Regarding the KEA128BLDCRD solution, it seems that the solution is only for reference design, you can not order the power stage board and BLDC motor, but I am not sure. Another drawback of the solution is that the KEA only supports sensorless solution, the KEA128 FTM can not connect encoder which is position sensor.
I think the above link is okay. You can establish the tower system with the boards:
Power stage board and BLDC motor:TWR-MC-LV3PH Low-Voltage 3-Phase Motor Control module with a BLDC motor
Flank boards:TWR-ELEV primary/secondary boards
Controller boards:TWR-K60N512, TWR-56F8257, TWR-K40X256, TWR-KV46F150M, TWR-KV31F120M, TWR-KV10Z32 and TWR-KV11Z75M, one of them is okay.
communication boards:TWR-SER board for Freemaster tools
Hi XiangJun Rong,
Thanks for the solution. But why can’t I use KEA128BLDCRD? Why can’t I order that demoboard?
I am also working on developing a motor control ESC using NXP eval boards.
I use the FRDM-KV31F MCU board and the FRDM-MC-LVPMSM with Kinetis Motor Suite(KMS) to drive the drone motor. (www.nxp.com/kms)
The drone motors is a BLDC motor (a subset of PMSM motor types) that is driven with KMS with an FOC method. KMS allows users of all experience levels to tune and drive a motor.
You might consider this path in your design decision.
Hi Philip Drake,
Appreciate your response.
What is the application that you're the drone for?
What are the specifications of the motor that suits the evaluation board? Do we need to have 4 of these for developing a prototype?
I have checked the website, you can order the KEA128BLDCRD board from the website:
3-phase Sensorless BLDC Motor Control RD|NXP
If you control a BLDC, it is okay to use KEA128 with sensorless or hall sensor.
