Part Number: MCF8329A
Other Parts Discussed in Thread: MCT8329A

Tool/software:

Hello，

The customer uses MCF8329A to control a brushless motor with a power of 300W and a 48V voltage drive. There are the following questions that need to be consulted. Please help analyze or provide good suggestions.

Question 1: Which startup method is better? Currently using IPD.

Question 2: Always reporting faults during acceleration phase after startup.

Question 3: How to debug on load startup?

Question 4: When driving a brushless motor, is it better to use the ladder control chip MCT8329 or MCF8329? Which is more suitable?

Thanks！

    Could you list the faults you are observing?

    Could you provide more details on the load? Are we seeing faults during startup?

    Both devices can be used to drive a brushless motor. MCT8329A has a trapezoidal control integrated into the motor and MCF8329A has an FOC control.

    MCT8329A can be used in applications where there is a high speed requirement whereas MCF8329A is ideal for silent and efficient operation but is limited in maximum speed it can drive compared to the MCT8329A
