Servo Motor Details
The Z servo motor is a Motor Power Company Penta 5M 60 Volt, 3000 RPM 860 in/oz peak torque. I acquired three of these motors from EBay. I need to install an encoder on it.
I will be driving the servos with gecko 320 drives
I have on order (3) US Digital E2 500 Count encoders, I will need to turn the shaft down to .375 for the encoder. I hope to make some nice alum covers for the encoders as well.
Because I will have no counter weight to offset the weight of the head I'm going to be installing a brake on this servo as well
Here is the Z servo with brake, brake cover & encoder
This is a 24volt brake that is active when no power is applied
X and Y servo motor are Reliance Electro Craft 643's. I also found
these on eBay. I will need to mount encoders on these motors as well
The stepped down back of the motor is a built in tachometer. I have no need for the tach, I will remove the tachometer and mount an encoder in its place. I plan to make a new aluminum cover for the encoder and mount the connectors to the cover as well.
|Here is one of the encoder/connector covers that I made for the X&Y servo motors|
|CB style mic connectors will be used for connections to the servo
motors. I machined off the center flange so the connector can be
inserted from the back, it will require two nuts to hold them in since
the flange is gone.
|Here the connectors are being installed|
