The new generation of high-efficiency IE5+ synchronous motors (photo) combine the benefits of this company’s modular system of gear units, motors and variable frequency drives (VFDs) with the possibility of reducing system variants through constant torque over a wide speed range. Their ventilated variant (F-Design) features high overload capacity while effectively dissipating heat for logistics, packaging and post and parcel applications. NORDAC ON/ON+ VFDs were designed for the special requirements of horizontal conveyor technology and use with IE5+ motors. They are characterized by an integrated Ethernet interface, full pluggability, and a compact design. These VFDs ensure smooth operation with precise control of speed, positioning, and synchronization. The new DuoDrive integrated gear unit/motor concept combines a high-efficiency IE5+ motor with a single- stage helical gear unit in one, compact housing. — NORD Gear Corp., Waunakee, Wis.
