The 2/3 pitch copper winding minimises harmonic distortion, and Class H insulation with vacuum pressure impregnation ensures outstanding thermal performance. All units are manufactured to IEEE 115, NEMA MG1, and IEC 60034 standards. SAE bell housing configurations ensure compatibility with all major diesel engine brands. Single-bearing and double-bearing options are available across the full power range.
