MRL elevator
MRL elevators utilize a gearless Permanent Magnet Synchronous Motor PMSM with 5.5 to 18 kW power output. The motor is installed directly in the hoistway overhead, eliminating the need for a separate machine room. Travel speeds range from 0.5 to 4 m/s with adjustable stopping accuracy of ±3 mm. Cabin capacity spans 450 to 2000 kg for 6 to 26 passengers, designed with a 1.25 safety factor. The control system employs inverter drives with regenerative energy recovery and 95% overall efficiency. Energy consumption complies with ISO 25745-1 Class A++ standards, using 30% less energy than conventional models. All components are certified per EN 81-20/50, ASME A17.1, and ISO 22201-1 standards.
The compact structure integrates the motor directly with the traction sheave and 2:1 or 1:1 suspension systems. The cabin is constructed from lightweight aluminum panels with 40 dB acoustic insulation and Class A fire-resistant coating. Safety systems include electromagnetic safety brakes, overspeed governors, and 3D laser sensors. Automatic doors feature 120W synchronous motors and 5 mm obstacle detection capabilities. Guide rails use KP100 steel with 150 Brinell hardness and 80-micron hot-dip galvanized coating. Installation and maintenance employ IoT monitoring systems and predictive mainten
