Whereas SCIMs cannot turn a shaft faster than allowed by the power line frequency, universal motors can run at much higher speeds. This makes them useful for appliances such as blenders, vacuum cleaners, and hair dryers where high speed and light weight are desirable. They are also commonly used in portable power tools, such as drills, sanders, circular and jig saws, where the motor's characteristics work well. Many vacuum cleaner and weed trimmer motors exceed 10,000 rpm, while many similar miniature grinders exceed 30,000 rpm.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What attributes make universal motors desireable for consumer applications like hair dryers?
Ah, so.. high speed and light weight

In the 1950s after PRC was established by CPC, the government invested heavily in the city to build a series of state-owned heavy industries, as part of the national plan of rapid industrialization, converting it into a heavy industry production centre of East China. Overenthusiastic in building a "world-class" industrial city, the government also made many disastrous mistakes during development, such as spending hundreds of millions of yuan to mine for non-existent coal, resulting in negative economic growth in the late 1960s. From 1960s to 1980s there were Five Pillar Industries, namely, electronics, cars, petrochemical, iron and steel, and power, each with big state-owned firms. After the Reform and Opening recovering market economy, the state-owned enterprises found themselves incapable of competing with efficient multinational firms and local private firms, hence were either mired in heavy debt or forced into bankruptcy or privatization and this resulted in large numbers of layoff workers who were technically not unemployed but effectively jobless.

Ah, so.. "world-class"

After Congress passed the Communications Assistance for Law Enforcement Act (CALEA, 1994), the Health Insurance Portability and Accountability Act (HIPAA, 1996), and the Economic Espionage Act (EEA, 1996), the FBI followed suit and underwent a technological upgrade in 1998, just as it did with its CART team in 1991. Computer Investigations and Infrastructure Threat Assessment Center (CITAC) and the National Infrastructure Protection Center (NIPC) were created to deal with the increase in Internet-related problems, such as computer viruses, worms, and other malicious programs that threatened US operations. With these developments, the FBI increased its electronic surveillance in public safety and national security investigations, adapting to the telecommunications advancements that changed the nature of such problems.

Ah, so..
