Achieving high efficiency exceeding IE4! Compact and lightweight! Mounting dimensions compatible with general-purpose motors!
The NPM1 series is an IPM motor that achieves significant efficiency improvements by embedding permanent magnets in the rotor, while also offering high responsiveness. ■ High efficiency exceeding IE4 standards The motor alone achieves efficiency exceeding IE4 standards. ■ Energy-saving effects Motor: 200V/3.7kW/60Hz Annual operating time: 4000 hours Electricity rate: 16 yen/kWh Under the above conditions, it is expected to achieve an annual energy-saving effect of 23,690 yen compared to standard efficiency motors. ■ Smaller and lighter compared to general-purpose induction motors. Compared to general-purpose induction motors, it has a volume ratio of 53% and a weight ratio of 62% (Note: compared to 7.5kW, 1800min-1), contributing to the compactness and space-saving of machinery. ■ Compatible with general-purpose induction motors for installation. Customization available. The shaft dimensions and mounting dimensions are the same as those of general-purpose induction motors of the same capacity, allowing for direct replacement. Additionally, we can accommodate mounting requests based on customer needs. ■ Exempt from top-runner systems and various overseas regulations As an IPM motor, it is not subject to energy-saving regulations in various countries like induction machines.
