Man my head is starting to spin! No wonder people just go with steppers and call it a day. Maybe my vision is clouded by ignorance but it doesn't seem like it should be that hard to pick up a brushless DC motor, a suitable amp and make it work. Obviously it would be easier to just buy a sorted motor/driver, but then it would be easier to buy a sorted CNC machine as well.
So getting back to the motor amp combination for a second someone have a look at hese for a minute and tell me what you think. This is the motor I am using: http://www.servodynamics.com/Drawing/23S-IE.pdf I am using the IG23CS-64-IE2000-S Servo dynamics recommends the 1224-BLS driver for this motor. The 1224BL is the comparable amp: http://www.servodynamics.com/Specs/1224bl_spec.pdf And here are the amps I was looking at using: http://www.a-m-c.com/download/datasheet/bd30a8.pdf Servo dynamics says I am fine driving with either sinusoidal or trapezoidal. The AMC is trapezoidal. Obviously need to add a filter card, but otherwise it looks to be in the ballpark.
