Freight Elevator Replacement Motors
Freight elevator replacement motors are needed when the motor that controls the door or gate of an elevator dysfunctions or breaks down. These motors may also be replaced preemptively as part of regular maintenance and periodic equipment updates.
Since these electric motors are performing a critical function, replacements are often needed with some urgency. This is why some motor suppliers and manufacturers stock single units to serve as gate elevator replacement motors.
The maintenance and repair of freight elevators can pose their own challenges to motor replacement. These motors can be more specialized than motors used in passenger elevators, as they typically must accommodate more weight.
Purchasing a single elevator motor directly from an OEM can be a challenge. In most cases, larger motor manufacturers and distributors do not sell single replacement units for elevator repair. Even when single or smaller quantities of motors are available for sale, OEMs may not be able to provide the expedited order fulfillment required for an urgent freight elevator repair.
Some motor manufacturers and suppliers have specifically set out to solve this problem for maintenance professionals and repair technicians. Motor manufacturers will sometimes maintain a stock of gate elevator motors that are readily available for expedited shipment and urgent repair needs.
Additionally, replacement motors for freight elevator doors are sometimes required to enhance the performance or improve the longevity of an automated or electronic lift system. Commercial-off-the-shelf motors may not provide operation that’s as reliable or long-lasting as motors made in smaller quantities from independent motor manufacturers.
If customizations are needed to correct or bypass an issue that’s causing the need for frequent motor repair, a small manufacturer can sometimes offer motor design and modification services for elevator motors.
What Type Of Motor Is Used In An Elevator Lift?
Geared AC motors are sometimes used to power the hydraulic lifts within an elevator system. Newer designs will use 3-phase induction motors and variable frequency drives. In some settings, brushless DC motors with permanent magnets are used. These motors must provide a lot of torque and operate smoothly.
How Much Does An Elevator Motor Cost?
The cost of elevator motors can vary considerably based upon the type of elevator system. The type of motor and degree of customizations required will also factor into the total cost of a replacement motor. When considering the cost of a replacement elevator motor, remember to factor in the quality of the materials and the motor’s design, as this will factor into longevity as well as performance. A low-cost motor may not last as long as one that uses higher quality parts and will therefore need to be replaced or repaired sooner.
What Does An Elevator Drive Do?
An elevator drive describes a system that enables the elevator to operate. There are different types of elevator drive systems, including traction elevators, hydraulic elevators, rack and pinion elevators, and pneumatic vacuum elevators. Motors used in many of these systems are typically low-RPM, high torque motors.
How Long Do Elevator Motors Last?
The lifespan of an elevator motor will depend on a number of factors, including the quality of the components, type of motor, elevator system, and overall maintenance. An individual elevator motor should last at least several years, provided it is manufactured with reliable components, is built properly, and is correctly installed in the application. An elevator system itself, when well-maintained, will typically last between 15 and 20 years. Elevator motors are one of the more major parts of the system that will require intermittent replacement in order to maximize the operation of the overall system.
