Advantages Of Gear-less Machines Used In Elevators

Features of Gear-less Machines used in Elevators:

A Gear-less Machine adopts a disc brake, which has more advantages than the traditional drum brake. The rate of malfunction is lower, which means it’s safer, and no circumstances of brake getting stuck. The noise of opening and closing brake is lower. The adjustment of clearance between brake force and brake disk is more labour-saving and convenient. Adjustment is hardly ever needed in daily running.

Brake absorption current is one half lower than that of a drum brake. A gear-less machine is built with equipment of pressure decline after brake starts working, which is no longer needed in the control box. The starting torque of a Gear-less Machine is strong, and the current of starting operation is smaller than the similar products. It can match lower power transducer, and save cost. According to strong starting power and low current, the physical volume of a Gear-less Machine is smaller than the similar kind of products.

According to the special design of a Gear-less Machine coil, the low speed starting and braking pulsation is less than similar products. A Gear-less machine does not have a gearbox, thus they do not require any type of oiling. Gear-less machines are considered superior to Geared Machines because they are more efficient and quieter in operation, requires less maintenance and has longer life. Due to the AC drive control, brake wear is virtually non-existent. It saves about 50% of energy consumption,  and thus it consumes less current. Also frequent start-stop motion of the elevator will not cause any negative impact on this system. Gear-less Machines are used where the rise is more and very smooth & high speed operation is desired.

Summing up a Gear-less Machine has the following advantages:
1.No risk of oil contamination.
2.Nearly unlimited floor travel.
3.Has greater efficiency.
4.Has superior speed and performance.
5.Smooth & jerk free ride, high reliability, less noise and has a longer life span.
6.Safer ride when compared to a geared machine.
7.Saves on energy, actual consumption is about 50% that of geared machines.
