Workplace, is amongst the drawings Elisha Graves Otis submitted along with his "Hoisting Apparatus" patent dated January 15, 1861. I have colored it in a bit so It is really much easier to understand.

Gearless traction machines are small-speed (lower-RPM), superior-torque electric motors run either by AC or DC. In such a case, the drive sheave is straight hooked up to the top on the motor. Gearless traction elevators can achieve speeds of up to 20 m/s (four,000 ft/min), A brake is mounted concerning the motor and gearbox or between the motor and drive sheave or at the conclusion of the drive sheave to carry the elevator stationary in a floor. This brake is usually an external drum kind and it is actuated by spring power and held open electrically; an influence failure will lead to the brake to interact and stop the elevator from falling (see inherent safety and safety engineering). But it surely can even be some type of disc type like one or more calipers above a disc in a single close in the motor Check Out Your URL shaft or drive sheave which can be Employed in superior velocity, large rise and huge capacity elevators with machine rooms (an exception could be the Kone MonoSpace's EcoDisc which is not significant pace, large increase and large potential and is particularly machine space much less but it surely works by using exactly the same design as is usually a thinner Edition of a traditional gearless traction machine) for braking electrical power, compactness and redundancy (assuming there are actually at the very least two calipers around the disc), or a number of disc brakes by using a single caliper at one lift repair services end with the motor shaft or generate sheave which happens to be Utilized in machine area much less elevators for compactness, braking power, and redundancy (assuming there are two or more brakes).
On the whole, most elevators prior to WWII ended up manually controlled by elevator operators using a rheostat connected to the motor. This rheostat (see photo) was enclosed within a cylindrical container concerning the sizing and shape of a cake.
