Countries with high energy behind the mechanical and electrical equipment (products) out of a catalog, "high energy behind the mechanical and electrical equipment (products) out of the directory (the first)," the leading energy-saving motors, on December 4, 2009 release of execution. A total of nine categories 272 equipment (products) out, including the electric motor 27, welding and resistance furnace 13 subsidized energy-saving motors, four transformers and voltage regulators, 50 boilers, fans 15 two energy-saving motors, pumps 123 items, compressor 33, diesel 5, two other devices. 2 "high energy behind Electrical Equipment (product) out of the directory (second batch)", executed since October 1, 2012. A total of 12 categories 135 equipment (products) out, including an electric motor, industrial boilers 8, 61 appliances, transformers 1, a welding machine 34 energy-saving motors, 20 forging equipment, heat treatment equipment 2 refrigeration equipment 1, a valve, pump 2, 3 other equipment. 3, the Ministry will prepare release of "high energy behind the mechanical and electrical equipment (products) out of the directory (the third)," in the 2014 second quarter, third quarter, the organization of key users of high energy behind the mechanical and electrical equipment for supervision and inspection. Ultra-efficient motor improvement in every aspect of the energy loss: 1. Optimized design reduces mechanical losses △ Po-quality ball bearings to reduce friction and vibration reduction locking end bearing clearance fan and fan cover design for optimum cooling and??? quieter operation? smaller fan produces a smaller loss? lower operating temperature so that a smaller motor fan 2. The optimized design can be used to reduce the stator copper loss △ PCu1? more winding? Improved groove Design? ISR (Inverter Spike Resistant) magnet wire to provide up to 100 times the voltage peak resistance? stator ends of straps on both ends? low temperature (<80 ° C)? F class insulation system? allowed The maximum temperature limit, run every 10 ° C lower temperature insulation life can redouble 3. Optimized design reduces the rotor copper loss △ PCu2 and mechanical losses? Improved rotor insulation? high-pressure die cast aluminum rotor? The design reduces rotor balancing iron loss △ PFe1? thinner silicon steel laminations? improved characteristics of the steel in order to achieve lower losses and provide the same performance? optimized gap leading energy-saving motors, Dresdner Cheung motor (certified), energy-saving motors from Mianyang Zhengzhou Dresdner Cheung Motor Manufacturing Limited.
