EC Motor: Nidec Motor Corporation
Nidec Motor Corporation (NMC) has launched the U.S. MOTORS® brand 3-10 hp electronically commutated (EC) motor with an IE4 (Super Premium efficiency) rating integrated with a tuned VFD. The product is available for variable torque pumps, fans, blowers, farm vents, and hydronic pumps. This motor is a member of the ACCU-SERIES line of variable speed products.
The company says the new product is the only integrated EC motor in the marketplace that is rated IE4. The new integrated motor and drive was designed with ferrite magnets rather than rare earths for more consistent pricing and cost structure. The Brushless Permanent Magnet Motor (BPM) and drive have an integrated user interface to streamline setup. Nidec officials claim the product is simpler than a modular approach, and it reduces costs and lead-time by eliminating cabling between motor and separate control. It also reduces electromagnetic interference (EMI) and corona, which can result in power loss and interfere with performance.
The motor is designed to mount in all standard NEMA or IEC mechanicals/constructions, has an IP54 rating, and can replace an induction motor and off the shelf drive. No customer connection is required.
