Resistance Start—Induction Run (RSIR) This motor, also known as a split-phase motor, is used on many small hermetic compressors up through 1/3 HP.
3-Phase Induction Motors - UNLV
www.egr.unlv.edu• The basic idea of an electric motor is to generate two magnetic fields: rotor magnetic field and stator magnetic field and make the stator field rotating. The rotor will constantly be turning to align its magnetic field with that of the stator field. • The 3-phase set of currents, each of equal magnitude and with a phase
Determining Electric Motor Load and Efficiency
www.energy.govparameters taken from hand-held instruments, you can use Equation 1 to calculate the three-phase input power to the loaded motor. You can then quantify the motor ’s part-load by comparing the measured input power under load to the power required when the motor operates at rated capacity. The relationship is shown in Equation 3. Equation 1 ...
