1 Record The 3 Phase Induction Motor Name Plate Details

The 3 beside phase on the nameplate in figure 1 indicates that this is a 3 phase ac motor the motor operates on 3 phase ac power. Most industrial ac induction motors are rated 3 phase which means that the ac power supply is three separate yet interconnected single phase ac lines with the voltages across the respective windings 120 out of phase with each other. Looking for dayton 1 3 hp general purpose motor 3 phase 1725 nameplate rpm 208 230 460 voltage 48 frame 3n350.
