The Challenge
• The existing DC Motor Generator controlled systems installed in the lift motors in London's The Economist Building were inefficient, consuming 66kWh/day per lift.
• An increasing number of breakdowns resulted in a higher level of maintenance support needed to keep the unreliable system operational. Also, sourcing replacement parts was an issue.
The Solution
• Three 85A Quattro AC Elevator Drives configured in permanent magnet motor control operating mode were installed.
Results
• Installing Quattro AC Elevator Drives resulted in energy savings of 66% when compared to the previous DC Motor Generator solution.
• Power usage measured by Jackson Lifts was reduced from 66kWh/ day with the previous DC Motor Generator Control to 23kWh/day with Quattro AC.
• Projected energy savings is £1100 per annum per lift.
• The maintenance support required was reduced.
• Elimination of generator decreased noise and
resulted in a cleaner system.
• The new solution ensured less heat and more floor space in the machine room.
• Lift speed increased from 2.5 to 3.5m/second.
New York City, NY
Magnetek Elevator's installation of Quattro AC drives into the 285 Madison Avenue elevator systems has resulted in faster floor-to-floor times, improved responsiveness, and qualification for gold-level LEED certification, along with additional energy-efficiency building credits. Magnetek green elevator drives contribute to more efficient operations, matching the modern, streamlined design of the building. Full structural renovations were completed in early 2015, featuring a convenient direct-to-roof elevator for tenant access to the beautiful rooftop lounge.
SmartRise Engineering
SmartRise Engineering, Inc., a state-of-the-art, non-proprietary elevator control manufacturer, was in need of a suitable drive solution to power the machine room-less (MRL) elevators being modernized in three buildings across the United States. SmartRise chose to update the drives with Magnetek HPV 900 Axial Flux Permanent Magnet AC Motor Drives at each of the sites, which provided considerable performance, serviceability, and cost improvements.
