Record The 3 Phase Induction Motor Name Plate Details

Unless you have a unique application your motor will be rated for single phase or three phase input power.

Record the 3 phase induction motor name plate details. Anushree rajendrarao helonde mr. Mahesh mankar identifying three phase induction motor equivalent circuit parameters from nameplate data by different analytical methods published in international journal of trend in scientific research and development ijtsrd issn. The motor is able to supply a shaft output of at least 15 kw if connected to the mains supply as indicated. 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. Figure 1 typical induction motor nameplate information. The rated output of the motor is 15 kw i e. This name plate shows a frame size 326t.

Details of full name plate main part of ip insulation class etc etc. The frame size provides a standard for details such as the location of mounting holes a height of the shaft above the mounting plate etc. The nameplate for a two pole 15 kw motor may have the following important data. Manufacturer s type and frame designation nema defines standard frame sizes.

Rpm speed the rpm listed on the nameplate is the shaft speed for the motor.
