ClearPath Servo Motors

Well after so many requests for information on ClearPath servos for the PM I contacted Teknic and spoke with a engineer to figure out which servo's best fit the PM727 CNC conversion. This is what she came up with. Please note I choose to bump up to a bigger motor on each Axis. Thanks for watching , please subscribe, thumbs up if you like the video, and most importantly , Be Safe!

Z Axis:

For this axis, you have the option to choose between two different motors depending on your preference for more torque or more speed. I'll list the specifications I used to run the simulation. Then I'll list the two motor options and what specs they are able to achieve as well as the differences between them.

5mm lead, 20 mm diameter ball screw
120 lbs load weight
Range of move length 0.01-15in

For this axis, you could choose between a CPM-SDSK-3421S-RLN or a CPM-SDSK-3421P-RLN. The difference between the two motors is the windings.

CPM-SDSK-3421S-RLN: https://www.teknic.com/model-info/CPM...
This "S" winding is designed for higher torque at lower speeds. However, with this motor, you could still achieve almost 200 ipm.
CPM-SDSK-3421P-RLN: https://www.teknic.com/model-info/CPM...
This "P" winding will give you a bit more speed, but at the cost of torque. While the motor has plenty of design margin in terms of torque for your application, there is less available than with the "S" winding. However, this motor will be able to give you a speed of close to 350ipm

Either motor will be able to achieve the specs that you are looking for in your application. However, depending on which model you choose, you'll have either more speed or more design margin regarding torque.

X and Y Axis:

For these axes, I am recommending the CPM-SDSK-3411S-RLN. Again, if you would like more design margin in terms of torque, you could move up one size. Additionally, some people prefer to keep the motors on all axes the same, but this is a personal preference (if you decide to do this, you would use the larger motor on all three axes). Just to summarize, the specs that I ran this simulation with were as follows:

5mm lead, 20 mm diameter ball screw
50-100 lbs load weight
Range of longest move: 10-15in

All three simulations were run using a 75VDC power supply.
Choose ClearPath IPC5 500watt
