Gearless traction machines are very low-speed (lower-RPM), large-torque electric motors run both by AC or DC. In this instance, the travel sheave is instantly hooked up to the end with the motor. Gearless traction elevators can reach speeds of up to twenty m/s (four,000 ft/min), A brake is mounted in between the motor and gearbox or involving the motor and travel sheave or at the conclusion of the travel sheave to carry the elevator stationary at a floor. This brake is often an exterior drum style and is actuated by spring pressure and held open electrically; an influence failure will induce the brake to have interaction and forestall the elevator from falling (see inherent safety and safety engineering). But it surely will also be some form of disc type like a number of calipers more than a disc in a single finish on the motor shaft or push sheave and that is used in large speed, superior rise and large capability elevators with machine rooms (an exception would be the Kone MonoSpace's EcoDisc which is not superior speed, substantial increase and huge potential and is particularly machine area fewer nevertheless it works by using exactly the same design as is usually a thinner Edition of a standard gearless traction machine) for braking electrical power, compactness and redundancy (assuming you will find at least two calipers over the disc), or a number of disc brakes using a single caliper at 1 end with the motor shaft or drive sheave which happens to be Employed in machine space much less elevators for compactness, braking electric power, and redundancy (assuming There's two or more brakes).
