Reduced losses due to air movement. Keyed and clamped to prevent movement on the shaft. Rotor - Die cast aluminum with steel laminations. Phase insulation included for inverter duty . Windings - More copper and larger conductors increase cross sectional area of the stator.
Lower resistance reduces losses due to current flow.
These motors also have the CSA C390 logo verifying compliance with the Canadian Standards. This includes procedures for segregating and smoothing stray load loss test values in order to minimize random test errors. 1.25 S.F. Ask for Assistance.
