The
DigiRout 1000 Pro has high torque NEMA 34 round frame
DC
Brush
Servomotors available for all axes
(double stack length on the X & Y& Z axes).
The picture above shows the construction of the motor. The
robust large diameter rotor which along
with the rare earth magnets provides an ultra high 1125 oz-in of Peak
torque. The skewed rotor design ensures smooth low speed
motion
without "cogging". The high resolution (500 per rev) incremental
position encoder provides feedback to ensure no loss of postioning.
These high torque digital motors combine
affordability and reliability for the prime movers of the DigiRout.
The G320x drives is a recently revised design taking advantage of the
latest CPLD (Complex Programmable Logic Devices) to process the encoder
and step & direction motion signals along with a
mature proven
power output stage rated for 70 VDC and are made in the USA.
