驱动电机机会几何——随着电池技术的迭代加快，电动车续驶里程的短板制约将日渐消弭，消费者对电动车的比较将更多着眼于它的亮点，诸如动力性能，这其中电机的重要性将愈发凸显。未来四年国内车用驱动电机的需求量有望实现 40%的年复合增速，动力总成系统的累计市场觃模有望达1500 亿元。在早期新能源汽车试点推广阶段，车用驱动电机多是小批量、定制化的产品，其毛利率高值近 30%；而随着规模化量产的推进，新能源汽车驱动电机的毛利率水平将向工业电机趋近，考虑到车用环境的复杂性及所要求的高性能，其毛利率水平应高于工业电机，有望维持在 25%以上。

Since the invention of the first light bulb by Thomas Alva Edison in 1879, the lighting industry has gone through a series of technological advances. The discovery of Geissler tube in the early 19th century led to the development of fluorescent lights. Now, LED lighting, a kind of solid-state lighting, uses a semiconductor to convert electricity into light and can emit light in a specific direction. It is penetrating the market at a very high rate.

Underbars refrigerators are designed for bottled alcoholic beverages and are mostly used in the front-of-the-house bar area. Underbars refrigerators have multiple configurations including one to four doors, drawers, or slide tops. Many manufacturers provide underbars refrigerators in such a way that they can be stacked. The slide tops in the underbars refrigerator help the operator store one type of beverage or product in a small space. The length of underbars refrigerator ranges from 24 to 72 inches,typically increasing in 12-inch increments. The depth of underbars refrigerators ranges from 24 to 34 inches.In this report, Technavio covers the present scenario and growth prospects of the global underbars refrigeration market for 2017-2021. To calculate the market size, we have considered the revenue generated from the Americas, Asia-Pacific (APAC), and Europe, the Middle East, and Africa (EMEA). The report also presents the vendor landscape and a corresponding detailed analysis of vendors operating in the market. 

Transformers need an insulating medium to keep the temperature of the core windings in check as well as act as an arc-quenching medium. Oil is the most widely used type of insulating medium. Transformer oil is used as an insulation and arc-quenching medium in power and distribution transformers. Windings use cellulose insulation that has a strong affinity for oxygen and is immersed in transformer oil to prevent oxidation. Transformer oil is produced by the fractional distillation and subsequent processing of crude oil. It also finds application in circuit breakers and switchgears, which are traditional and use oil as the arc-quenching fluid. The global demand for renovation and expansion of the T&D network is on the rise, mostly triggered by the growing demand for electric power from almost every type of end-user, namely residential, commercial, and industrial sectors.

Ultrasonic cleaning uses ultrasound and an appropriate cleaning solvent to clean items. The water or appropriate solvent used depends on the type of objects being cleaned, where it usually takes between 3-20 minutes. Ultrasonic cleaning is a method used to clean objects such as jewelry, watches, dental and surgical instruments, tools,lenses and other optical parts, coins, fountain pens, firearms, car fuel injectors, golf clubs, fishing reels, window blinds, musical instruments, industrial parts, and electronic equipment.

The global vacuum generators market for industrial robots will be significantly impacted by the growth dynamics in the industrial robot market as well as the developments in the overall manufacturing sector. The market is expected to witness a CAGR of 8.35% during the forecast period.

Lighting in an automobile is considered a critical safety system, as it is vital for illuminating the path ahead of the automobile. The primary use of automotive lighting is to ensure visibility to the driver, improve vehicle conspicuity, and intimate the presence and position of the vehicle to others. Automotive lighting has evolved over the past decade from being a mere functional system to a component that enhances the aesthetics of the vehicle. One such extension is ambient lighting, which is used to illuminate the interiors of the vehicle to provide a soothing and spacious look to the cabin.

In this report, Technavio covers the present scenario and the growth prospects of the global traffic lights market for 2017-2021. To calculate the market size, the study considers the revenue generated from the sales of traffic lights (portable traffic lights and traffic lamps) at the manufacturer level.
