  1. Induction motor nameplate

  2. Nameplate Data (continued) • Nominal Efficiency • Average efficiency of many samples • Guaranteed Efficiency • Minimum efficiency when operated at rated nameplate values • Power Factor • Maximum Corrective KVAR Capacitor

  3. Nameplate Data (continued) • Design Letter • Service Factor (S.F.) • Indicates permissible loading at rated nameplate voltage, frequency, etc. (115%) • Insulation Class • Specifies maximum temperature rise above ambient • (Table 5.8)

  4. Nameplate Data (continued) • Frame Number • Determines mounting dimensions • Enclosure • Code Letter • Table 5.9 (kVA/hp) • Determine the expected locked-rotor inrush current
