Gearless traction machines are low-speed (low-RPM), high-torque electric motors powered either by AC or DC. In this case, the drive sheave is directly attached to the end of the motor. Gearless traction elevators can reach speeds of up to 20 m/s (4,000 ft/min), A brake is mounted between the motor and gearbox or between the motor and drive sheave or at the end of the drive sheave to hold the elevator stationary at a floor. This brake is usually an external drum type and is actuated by spring force and held open electrically; a power failure will cause the brake to engage and prevent the elevator from falling (see inherent safety and safety engineering). But it can also be some form of disc type like 1 or more calipers over a disc in one end of the motor shaft or drive sheave which is used in high speed, high rise and large capacity elevators with machine rooms(an exception is the Kone MonoSpace's EcoDisc which is not high speed, high rise and large capacity and is machine room less but it uses the same design as is a thinner version of a conventional gearless traction machine) for breaking power, compactness and redundancy(assuming there's at least 2 calipers on the disc), or 1 or more disc brakes with a single caliper at one end of the motor shaft or drive sheave which is used in machine room less elevators for compactness, breaking power, and redundancy(assuming there's 2 brakes or more).

What motivates an external drum brake held open electrically?
Answer: spring force

Hyderabad has a tropical wet and dry climate (Koppen Aw) bordering on a hot semi-arid climate (Koppen BSh). The annual mean temperature is 26.6 C (79.9 F); monthly mean temperatures are 2133 C (7091 F). Summers (MarchJune) are hot and humid, with average highs in the mid-to-high 30s Celsius; maximum temperatures often exceed 40 C (104 F) between April and June. The coolest temperatures occur in December and January, when the lowest temperature occasionally dips to 10 C (50 F). May is the hottest month, when daily temperatures range from 26 to 39 C (79102 F); December, the coldest, has temperatures varying from 14.5 to 28 C (5782 F).

Initially sympathetic to Wieser's democratic socialism, Hayek's economic thinking shifted away from socialism and toward the classical liberalism of Carl Menger after reading von Mises' book Socialism. It was sometime after reading Socialism that Hayek began attending von Mises' private seminars, joining several of his university friends, including Fritz Machlup, Alfred Schutz, Felix Kaufmann, and Gottfried Haberler, who were also participating in Hayek's own, more general, private seminar. It was during this time that he also encountered and befriended noted political philosopher Eric Voegelin, with whom he retained a long-standing relationship.

What ideology was Hayek originally in support of?
Answer:
democratic socialism
