Hello,

We are trying to find a Motion Controller chip that's very similar to IRMCK201 and wondering if you can recommend a chip that might be a good replacement. We have our own FPGA that interfaces with the parallel bus of the IRMCK201 and basically looking for a chip that does FOC and behaves much like the IRMCK201.

Thanks,

Mike

Hi @mikehassanpour,

A suitable replacement for IRMCK201 can be IMC302A-F064 or  IMC101T-F048

For more specific requirements please visit our iMOTION product page for more details.

Please let us know if any additional details are required.

 

Thanks,

Krupashankar

Hi Krupashankar,

Thanks for your prompt response to our inquiry! Please see the few questions and comments we have below.

Is there a block diagram of what's in the MCEs'?

The IRMCK201 has a nice block diagram showing the internals of the part.

Our interface is parallel, and our motor parameters are in a look up table. How would that change going to MCE solution?

We have two Resolves to keep up with. One on the motor and one on the axis of elevation and in a similar fashion for the our azimuth motor we have a motor resolver and az axis resolver that we track the two resolvers each with corresponding motion (elevation or rotation). We only elevate or rotate at any given time. One axis at a time.

I think we can keep our current gate drivers and power section, may need to add voltage level translation to the gate drivers etc.

How easy is it to access the internal registers of the MCEs? We need to be able to write to and read from them. Timing is critical in our application, for example our current SVPWM frequency is around 17.6KHz. Is that a programmable feature of the MCE?

Our motor resolvers R/D are 12 bits and aixs R/D are 16 bits and quadrature etc. Are these options available with your MCEs'?

Is there an Infineon FAE we can talk with that serves Massachusetts?

I am sure there are plenty of other things we can ask for, but that's all I can think of at the moment.

Best rehgards,

Mike

Hi @mikehassanpour,

Thanks for sharing the details,
iMOTION controller has an in-built motor control engine which is suitable to work with motors in sensorless mode and with Hall sensor feedback only.
To operate the motor with resolver feedback we propose to use one of our XMC series controllers, based on the execution speed, memory, and peripherals requirement. The link below provides the controllers available.
