Hello,

I want the motor to start smoothly, but maybe because it's sensorless, the motor won't start and I get a "Rotor Lock" error code.

Why is this so?
I attached a video.
Please check the video.

Can you solve this problem?

Please reply.

Hi @JasonLEE 

Can you please provide with the latest .mc2 file?

We would like to understand the motor parameter configuration.

Best Regards

Hello @Viswa 

The motor cannot be started and is constantly shaking.

Since then, "GK" and "Rotor Lock" have occurred.

UART works only once out of 10 times.

IPM is very expensive and very unreliable. It's a repeat of popping or not working all the time.

I've been developing it using Infineon products, but it's really serious. There's no progress.

Why isn't Hall Sensor recognized?

This problem occurred when the motor driver was built into the motor. I think it worked well when motor drive was outside.

Can I send Infineon's motor and hardware for help?

Please reply

Hello @JasonLEE 

Before sending the motor and hardware, let us know which board and motor you are using. Was there any modifications to the last board? 
Please send us your latest schematics of the power board and motor datasheet.

Hi @RupakC 

Long time, no see.
How have you been?

I sent you the motor and the motor driver data I am are using before. Do you remember?

If you need more data, I will send it to you.

I attached Google Drive as a message.
Please check.

Only the expensive IM828XCC's IPM is really many damaged. What's really hard is that the motor is different every time it operates.
Sometimes it works well, but sometimes it doesn't even start. I hope it works well every time, but if there is a problem like this every time, it is very difficult to develop and commercialize it.

The price competitiveness is also very bad.
But I want to use the Infineon product.
please help me.
I have been struggling with this hardware for years now.

Hi @JasonLEE ,

I complitly agree with you , infineon needs to focus to solve this unrelible  and unexpected works on its ipms and motor controller ic. Those semiconductors have really problamatic production line i think and this makes them the worst. Since i had to redesigned many of pcb and lots of order from world wide distributers still cannot drive motor smooth and stable yet. I think infineon is only focused for their own eval boards not for custom boards.

Hello, @qwertyqwq35 

I totally agree with you.

I designed the reference design 100% accordingly, but there are so many problems that I haven't solved for years. Also, I've invested a lot of money in PCB redesign, but I still haven't solved the problem. And customized boards are actually not normal. It's not working properly.
And the unit price of IPM is ridiculously expensive. After choosing the Infineon design, I lost a lot of money.

Infineon engineers cannot solve this problem.

It's really frustrating.

Hello @JasonLEE 

Based on the previous threads created, we worked on some issues related to the operation of two motors.

For the smaller motor, we resolved all of the issues and concluded that a bigger motor was needed that could carry more current than 5A.

For the larger motor, in https://community.infineon.com/t5/Motor-Control-ICs/I-have-started-testing-a-new-motor-However-the-R... , the following issues were observed:

1. RPM did not rise
2. IPM exploded.
3. Windings of the motor overheated and the motor became extremely overheated

We worked together and solved the first two issues. For the third problem, we understood that the current drawn by the motor to drive the load was more than the IPM rating so a design change was needed.

For the present issues, can you let us know what changes were made such that new problems are being observed.
