Portescap precision 3 phase motor is about 1.6" long x 0.87" diameter. It has a 3mm diameter x 0.35" long shaft. The 3 leads are:
Phase 1 - Grey
Phase 2 - Violet
Phase 3 - Blue
We believe it operates on 24V, however we do not have the specs or hookup information, so we are not sure. Brand new - worth many times our price!
