Saving Money by Providing Upkeep to Machinery

By making modernizations and updates to your elevator machinery, you can not only extend the life of your units and parts, but you can also save money on replacement and energy costs. Check out a few updates you can make to your lifts, stair chairs and elevators that can save you cash in the long run.

Replacing the Motor Drive

In the past, motor generator technologies were able to convert AC power to DC power in an effort to supply a DC hoist motor. That was a time when DC motors had better torque control than AC motors. But today’s modern AC digital drives don’t require the need to convert from AC to DC power, bringing with them many advantages, such as:

  • You get a lot more energy savings, as power is only being consumed while the elevator is in use.
  • Regenerative drives can contribute power back to the building.
  • Less heat is generated, translating to less work from your building’s cooling systems.

Old DC drive systems suck up more than 40,000 kWh of electricity every year! By modernizing your inefficient elevator, you can save 72 percent in energy costs.

Replacing the DC Motor

At the same time that you replace the drive, you should undertake conversion of the DC motor. By doing this, you get even more cost savings:

  • Lower your electricity bills with better power factor correction.
  • When you have a higher efficiency system, you use less energy.
  • Heat reduction reduces the amount of cooling needed in your building.

Smart Controllers

Modern digital controllers use statistics and advanced algorithms that can result in much higher performance with much better energy efficiency. That’s because smart controllers continually scan all activity and reassign calls as needed to cut down on wait time and energy consumption. By implementing modern controllers and new hoist motors, you can reduce your electrical usage by 60 percent.

Elevator Upgrades

If your existing elevators are old, you may want to consider updating them. Modernized lifts provide a better customer experience, to be sure, but all that new technology can also help your units last longer, run more smoothly, and detect issues before they become serious. Upgrading now can save you unnecessary downtime and hurried replacements, which saves you money in the long run.


It’s easier to prevent future issues when you keep a detailed operational log of your elevators. You can track how often each cab is used and called, which helps you predict which ones will need repairs or maintenance first. Nipping the problem in the bud on a timeline that works for you keeps you from an emergency situation that leads to hasty, expensive actions.
