I am now designing a DC motor with a optical encoder assembling at the end of the motor. After I have checked with the specification of the encoder, there are no problems for me to understand how it function and how it works.
Now, I would like to assembly the transmissive encoder onto the end of the motor. Then I have some problems happened:
- For 1 turn motor rotation, encoder will give out 500 signal (because of 500CPR), I don't know how to verify the signal correct or not. I am using a 2 channel encoder and hence the 2 signal will be 90 degree phase shift. However, I really don't know how to use CRO to measure a contiunous high frequency signal.
- If the assembly between encoder and motor has some problems (aliasment, eccentricty, perpendicularity, etc...) I would like to know that can I check the encoder signal to verify the regarding problems happened in my motor assembly?
- I just have a CRO, no other special equipments. And I would like to know which extra equipment is needed for me to test the encoder.
Thanks~
