Integrated motor-drive system that delivers IE5+ ultra-premium efficiency, precise variable speed control, and a drop-in design to most low voltage motors—maximizing energy savings and simplifying installation for HVAC, pumping, and industrial applications.

ABB’s ERH solution features a lightweight, IES5 efficient external rotor that bolts directly onto the fan hub, creating a compact, easy-to-install, maintenance-free direct drive system for superior airflow control in fan applications.

ABB’s LFH direct drive solution for high-volume, low-speed (HVLS) fans eliminates mechanical wear components like gearboxes and couplings, delivering ultra-efficient, quiet, and maintenance-free operation with maximum airflow and energy savings.
