Furthermore, vehicle tire and brake wear were responsible for annual 584.8 tons of coarse particles (PM 10) and 314.4 tons of fine particle matter (PM 2.5) emissions in the city whereas surface wear emissions were responsible for around 313.7 tons of PM 10 and 169.9 tons of PM 2.5 pollutant emissions in the city.

Abstract: This paper discusses cost-optimized interior permanent-magnet (IPM) synchronous machine drive designs and the impact that magnetic saturation and inverter cost have on their performance and design optimization. Cost-optimized designs for IPM machines and combined machine-inverter systems are compared for an automotive starter/alternator application.

This paper presents the design and experimental verification of a 6 kW interior permanent magnet (IPM) synchronous machine intended for an automotive direct-drive starter/alternator application. The machine was designed using a saturable lumped-parameter magnetic circuit model in combination with a Monte Carlo optimization process that minimized the machine-plus-converter cost.

* Two common measures of energy are British thermal units (Btu) and joules. All forms of energy can be expressed in these units. One Btu is the amount of energy needed to raise the temperature of one pound of water from 39 to 40 degrees Fahrenheit. One joule is the amount of energy needed to lift one hundred grams (3.5 ounces) upward by one meter (3.3 feet) while on the surface of the earth.

pub T1 RZK none paper nickel, pore size Metal foams are widely produced by using different techniques such as compaction and replication method. In this study, slurry method also known as replication method has been used to produce SS316L foams. SS316L powders (50wt% and 60wt%) were mixed with the binders and distilled water by using mechanical stirrer.

Capital cost evaluation was carried out using the percentage of delivered equipment cost method and the total capital cost for this pilot plant was estimated as One Thousand, Seven Hundred and Eighty-Two-Ringgit (RM 1,782.00 USD445.50).

Inverter saturation, commonly referred to as "clipping", occurs when the DC power from the PV array exceeds the maximum input level for the inverter. In response to this condition, the inverter typically adjusts DC voltage to reduce the DC power. This is done by increasing voltage above the MPP voltage, thus reducing DC current.

Pursuant to the Energy Policy and Conservation Act of 1975 (EPCA), as amended, the U.S. Department of Energy (DOE) must prescribe energy conservation standards for various consumer products and certain commercial and industrial equipment, including residential furnace fans. EPCA requires DOE to

By using the ferrite PM and SMC material, the material cost and manufacture cost of AFSPMM can be reduced greatly. A 675 W 3600 rpm AFSPMM is designed and analyzed in this paper. The commercial finite element method (FEM) package ANSOFT is used to analyze the motor performance and the d-axis current is set to zero to achieve the optimum torque characteristic.

A cost-effective, compact, efficient, and reliable electric traction drive is a key enabling technology for the electrification of vehicle propulsion systems. Heat dissipation has a significant impact on the power capability of power electronics, which leads to increased device cost and package volume or size. The

Total energy cost per month for inverter = RM154.14 – 30% = RM107.90 That means that you save RM46.24 every month using an inverter aircon And since the price difference between a 2HP inverter and non-inverter is RM780, it will take you 16.96 months to recover the cost.

Therefore, low cost, high reliability and low technological risk will likely remain a primary advantage of this technology for the future. 3.2 Brushless PM motors Brushless PM motors are designed so that, in the stator induce electrical magnetic field acting on the permanent magnets in the rotor [1]. There are several

The impact of regional infrastructure is less ambiguous in its impact on bank credit. Both forms of credit decline as regional transport problems increase, with the two variables comprising the quadratic form, jointly significant at the 5% level in both equations. The impact on supplier credit is to an extent the reverse. Figure 2 shows these
