For sale is a Pacific Scientific Brushless Servo Motor R45GCNA R2 NS NV 00. I tested it by connecting a source of 12VDC to various pairs of leads. That made the shaft change positions. No further testing was done. If you do not like this item for any reason, within 7 days of receipt, you can return it to me for a refund of your winning bid.
