Ultra-high resolution motor without
speed penalty
Animatics Corporation has augmented its SmartMotor line with a special, ultra-high resolution encoder option that operates at unprecedented speeds.

Servomotors have Controller, Amplifier, Encoder
The Animatics 2300/3400 series IP65 SmartMotors have the Controller, Amplifier and Encoder built into true Brushless DC servomotors, making it possible to eliminate the NEMA cabinet and excess cables
Now, sizes 23 and 34 are available with the "-VRE" option which stands for "Variable Resolution Encoder".
The SmartMotor can be programmed to increase its resolution to as much as 256,000 counts per revolution.
What is even more astounding is the speed at which the motor still operates.
The maximum resolution of 256,000 counts can be retained, even at speeds in excess of 5,000 rpm.
Most high resolution encoder products are speed limited because the data can not be transmitted back to the controller fast enough.
Because with the SmartMotor, the controller is inside the motor, this data transfer problem is gone, along with any concerns about signal integrity in electrically noisy, industrial environments because there simply are no cables.
This technology creates new opportunities for machine builders.
Systems can be built with very fast slew rates, but still allow motion to stop and position to sub-micron levels, such as one would do with Hard Disk Certification Equipment.
The machine designer no longer needs to choose between high resolution and high speed.
