TIME Elevators introduced this technology and have installed it at many locations all over in India. All of them have been running successfully. The reason we suggest to change is because gearless elevators are more energy efficient.
The reason behind that is geared motors consists of two main components namely, the motor and gear box. Moreover without the gearbox no oiling and greasing is needed which translate into lower maintenance costs. Gearless motors are also known as permanent magnet synchronous motors which provide high torque with a low speed.
