MCF8316AEVM: Motor efficiency does not meet expectations

?? ?
Prodigy 60 points
Part Number: MCF8316AEVM
Other Parts Discussed in Thread: MCF8316A

Tool/software:

Hello.
I'm having a new problem with testing motors.


In this graph you can see that our motor efficiency is only 68%, but when we use other driver boards we can reach 80%, so we think that this result is because we didn't debug accurately with motor studio.
So here are few questions that I would like to ask:
1. how can I improve the motor efficiency (no problems with the test equipment and motor)?
2. what are the factors that are causing my load speed to not reach the desired speed (I'm using closed loop)?
3. How do I adjust the dead time?
4. What is the size of the sampling resistor on the driver board?
5. What parameters can we change on Motor Studio?
Please try to tell me with pictures what should be done.

I would appreciate if you could get back to me as soon as possible.

    Hi ,

    Thanks for posting your question.

    I want to clarify with you about the device, are you reading as MCF8316A or MCF8316C? In any case, efficiency with MCF devices are best unless parameters are not configured well. 

    The parameters are how are you measuring R, L?  Are you using speed mode?

    Is it possible to share the JSON file and also motor R, L, KE  values?

    Answer to your questions

    1. how can I improve the motor efficiency (no problems with the test equipment and motor)?

    Let us get proper motor parameters, this minimizes angle error (Sensorless FOC) there by improving the efficiency.

    Gate driver slew rate, keep it maximum 200 V/us


    2. what are the factors that are causing my load speed to not reach the desired speed (I'm using closed loop)? Current Limit (ILIMIT) setting in FAULT_CONFIG1 which is for torque need to be adjusted until motor can reach rated speed. 


    3. How do I adjust the dead time? Integrated FET and dead time is taken care 


    4. What is the size of the sampling resistor on the driver board? This is internal to the device.


    5. What parameters can we change on Motor Studio?

    Please share the JSON, we will make changes and send with details.

    Thanks and Best Regards

    Hello.
    Thanks for your reply, I am reading MCF8316A. I am using MPET for parameter measurement and the measured parameters are shown below.


    The motor parameters R = 0.425, L = 0.64mH, ke = 28, and the speed mode I am using is Controlled by Duty Cycle of SPEED Input Pin. Below is the configuration file I am using. I checked my registry and The slew rate is 200V/us.

    What should I do to increase the efficiency of my motor?
    Maybe I need a more detailed step-by-step procedure, please use pictures to guide me which parameters to change. I would be grateful if you could reply as soon as possible.

    Thanks for your reply, but please help me quickly, I'm in a hurry and there is a big time difference between us, which causes me to not be able to consecutively talk to you, I sincerely hope that each of our conversations will be efficient, and I'd appreciate it if you'd reply as soon as possible!

    Hi,

    Sorry for late reply, this we week we are on holiday and hence please expect slow reply. 

    I made few changes to the JSON, highlights

    1. Changed open loop configuration (auto hand off to manual hand off)- This will not impact efficiency but helps for successful MPET

    2. Changed MPET configuration - This will help for successful MPET

    How to run MPET

    1. Load the JSON (provided here below)

    2. Goto MPET Tab

    3. Select Measure R, L,KE only . Do NOT select MECH

    4. After MPET is successful then enable MECH measurement.

    After MPET is successful , first disable Speed Loop and test only in current loop to understand the efficiency

    Then enable speed loop and continue testing.

    You can post current waveform here

    Thank you for your reply, I have a couple of unanswered questions right now :
    1. as you can see in the picture below, when unloaded I can reach the desired speed, but when I add a load my motor can't reach the desired speed, I'm using a motor studio and it's in closed loop mode.


    2. In closed loop i want it to accelerate quickly to my desired speed but it is very slow, I want to reach 3600rpm at least 14s, i want to shorten this process.
    Can you guide me to solve this problem, if this problem can't be solved maybe I will lose this customer forever so please help me.
    I am not familiar with motor studio yet, can you try to guide me with specific steps using pictures?
    We have an appointment with the client coming up soon, so I hope we have a very productive conversation!

    Hello,

    Please try the following general tips to try to increase both the max speed when under load and acceleration.

    For max speed:

    What is your motors rated max current? If it is above 0.125A, increase ILIMIT so that it is close to, but not over, your motors max rated peak current:

    For acceleration:

    Increase CL_ACC and spin the motor. If a loss of sync fault occurs, decrease CL_ACC.

    Regards,

    Joshua

    Hi,

    Did you try the suggestion provided in below thread? 

    Also, can you confirm moving to MCF8316C ?

    What is the rating of the motor? You can increase ILIMIT until max rating of the motor, please try and let us know.

    Can you share the waveform?

    Thanks and Best Regards
