What is gearless motor for elevator?

Gearless elevator motors can be smaller than geared elevator motors because they do not have gears. The gearless motors can be smaller than 1⁄2 of the geared motor. This makes the gearless motors more effective when it comes to the use of electricity. By making the engine smaller, the other parts would also be smaller.

What is a geared elevator?

Geared Traction Elevators have a gearbox that is attached to the motor, which drives the wheel that moves the ropes. Geared traction elevators are capable of travel speeds up to 500 feet per minute. The maximum travel distance for a geared traction elevator is around 250 feet.

How does a gearless traction elevator work?

Some traction lifts also have gears between the motor and sheave (geared lift), others will just connect the motor directly to the sheave (gearless lift). The cables/ropes are usually a multi-strand steel material for security, meaning that if one of the strands breaks, the cable still holds the lift car up.

What is gearless?

: traction without reduction gears (as in a high-speed electric elevator drive in which the driving sheave is mounted directly on the armature shaft)

What is geared traction machine?

As the name implies, the geared traction elevator machine utilizes a reduction gear with a high-speed motor to drive the traction sheave. In some materials-handling applications, geared machines are used for speeds of 600 fpm or more (3.0 mps) with excellent results. …

Is a traction elevator gearless?

Traction elevators are the most common type of elevator. They can be geared or gearless and both model types are driven by alternating current (AC) or direct current (DC) electrical motors.

What are the two types of traction elevator?

Geared and Gearless Traction elevators can be separated into three different categories:

• Traction Elevator.
• Geared Traction Elevator.
• Gearless Traction Elevator.
• Roped Hydraulic Elevator.
• Conventional Hydraulic Elevator.
• Hole-less Hydraulic Elevator.

What is MRL gearless lift?

MRLs save space by placing the compact, gearless machine directly in the elevator shaft. There is no need for a roof top machine room, which potentially lowers building construction costs. Gearless machines and counterweight configuration of MRLs increases energy efficiency and provides a smooth, quiet ride.

What are the two types of elevator system?

There are four main types of elevators: hydraulic, traction, machine-room-less, and vacuum.

• Geared and Gearless Traction Elevator. Geared and Gearless Traction elevators can be separated into three different categories:
• Hydraulic Elevator.
• Machine-Room-Less (MRL) Elevator.
• Vacuum (Air Driven) Home Elevator.
