Selection Guide & Positioning
-
By Cooling Type:
-
Air-Cooled (HV C / HV M / A-compact PLUS) : Standard choice for most industrial environments; simple maintenance.
-
Water-Jacket-Cooled (HV C Water-Jacket) : Optimal when ambient cooling is poor or when motor footprint must be minimized.
-
Flameproof (HV C Flameproof) : Mandatory for applications in legally defined hazardous zones.
-
-
By Power & Drive Type:
-
HV C Series: Covers medium-to-high power (up to 2.6 MW) and is primarily designed for variable-speed drive (VSD) applications.
-
HV M Series: Covers ultra-high power (up to 5.3 MW) with the largest frame sizes. Suitable for both VSD and direct-on-line (DOL) starting.
-
A-compact PLUS: Fills the 1.5–3.5 MW power band with a 675V design, likely optimized for specific industries like cement or mining.
