Motor friction losses and flow losses: friction losses and flow losses in the past people did not get the attention it deserves, it accounted for about 25% of the total loss of the motor. Friction losses are mainly caused by bearings and seals, may be (1) to minimize the size of the shaft, but the need to meet the output torque and rotor dynamics requirements; (2) the use of efficient bearings; (3) the use of efficient lubrication systems and lubricants; (5) the use of advanced sealing technology, the new seal usage reports if no spring, said shaft by effectively reducing the contact pressure, which allows the axis of rotation of 6000 rpm in order to reduce the loss of nearly 45mm diameter 50 W; flow loss is the energy-saving motor by the cooling fan and the rotor caused by the ventilation slots, for generating an air flow to cool the motor. Flow losses generally account for about 20% of the total losses of the motor. Fluid mechanics and heat transfer analysis of the entire motor complex ye3 energy efficient motors, its complexity analysis even more than the space shuttle parts, fluid mechanics and heat transfer good design will greatly improve the cooling efficiency of the motor and reduce flow loss. State purchase of fuel-efficient cars and high-efficiency motors fiscal subsidies given to the National Development and Reform Commission hearing to implement the State Council "to further intensify its efforts to ensure the realization of the" Eleventh Five-Year "emission reduction targets of the notice" (Guo Fa No. 12 [2010]) spirit, accelerate the promotion of the use of energy efficient products, energy-saving motors Zhengzhou recently, Choi, the National Development and Reform Commission, the Ministry of Industry and Information Technology jointly issued "on the issuance of" energy-saving products that benefit the project "fuel-efficient vehicles (1.6 liters and below passenger car) promote the implementation details of the notice "(hereinafter referred to as the" Notice "), Choi, the National Development and Reform Commission jointly issued the" on the issuance of "energy-saving products that benefit the project" Efficient Motor promote the implementation details of the notice "(hereinafter referred to as the" notice "), was officially launched in fiscal subsidies to promote energy-efficient cars and motors. Two "notice" clearly, the engine displacement of 1.6 liters and below, integrated operating condition of fuel consumption than the current standard of about 20% of gasoline and diesel passenger cars (including hybrid and dual-fuel vehicles) into the "energy-saving products that benefit "in the nationwide promotion, the central fiscal for consumers to buy fuel-efficient cars by 3000 yuan each to give a one-time subsidy payment from the manufacturer to the purchaser at the time of sale; for energy-efficient small and medium three-phase asynchronous motors, high voltage three phase three-phase asynchronous motor and rare earth permanent magnet synchronous motor were given 15-40 yuan / kW, 12 yuan / kW and 40-60 yuan / kWh subsidy. Thus saving motor business, efficient cars, high efficiency motor after becoming efficient lighting products, energy efficient air-conditioning subsidies for another fiscal enjoy energy-efficient products. Fiscal subsidies to promote energy efficient motors, is expected in 1-2 years, so that our high-efficiency motors market share increased from less than 5% to more than 30%, the annual saving of about 35 billion kwh.
