MRL Elevators
Techno Industries introduced this technology about a year ago and have installed it at around forty locations all over in Gujarat. 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. The features of MRL elevators are as follows:
- Minimal Headroom
- Low Running Cost
- Excellent Ride Quality
- Low Noise Levels
- High Duty Cycles
- Low Maintenance Cost
Below is the simple calculation.
| Details | Gear Motor | Gearless Motor |
| Efficiency of motor | 72 % | 85% |
| Efficiency of gear | 58 % | No Gear Box |
| Efficiency | Combined Eff. – 0.72 * 0.58 = 0.42 on | Total Efficiency – 85 % |
In the conclusion for every 100 units of electricity consumed by geared motors, only 42 units of electricity consumed by gearless motors, only 42 units of electricity is converted into mechanical energy and for every 100 units of electricity consumed by gearless motors, 85 units of electricity is converted into mechanical energy. As a result, you get a clear saving of 43 units of electricity. This results in saving 43 % energy savings.
