Freight elevators can’t operate without an electric motor. In the past, it was difficult to get ahold of a replacement electric motor without buying large quantities in bulk. This forced you to spend more money and stock up on motors that you don’t actually need. Fortunately, technological advancements have made it possible for manufacturers like ARC Systems to sell single units and small quantities of elevator replacement motors. No more spending money on excess motors–you’ll get exactly what you need. Here’s everything you need to know about replacement motors for freight elevators.
What Is A Freight Elevator?
A freight elevator is an elevator that transports goods through a multi-story building. You can ride in the elevator along with the freight, but most people load the freight in the elevator and transport it with no accompaniment. Freight elevators are commonly found in malls, warehouses, supply facilities and other businesses that transport a lot of goods.
In a house, a freight elevator is called a dumbwaiter. Dumbwaiters are increasingly rare, but some old houses still have working dumbwaiters that transport food and other goods between floors. Traditional freight elevators operated with a pulley system. Today, many freight elevators use electric motors and other technological advancements. They can’t operate without their motor, so when the motor breaks, you need precision-engineered replacement electric motors as soon as possible.
How Is It Possible To Manufacture Single Motors?
Before advancements in 3D printing, it took companies weeks of effort and thousands of dollars to produce a single gate elevator replacement motor. As a result, these businesses couldn’t make a profit by selling one motor at a time. They forced companies to buy large quantities at once so they could recoup their time and investment into the project. This was understandable, but it still created a hassle for people who needed replacement electric motors for high-performance applications.
Luckily, new technology like 3D printing and CNC machines has made it much cheaper and easier to produce freight elevator replacement motors. This also makes it easier for customers to buy motors directly from the United States instead of outsourcing to other countries. At ARC Systems, we carry a stock of freight elevator motors that replace the major types of motors. Simply browse our selection, place an order and wait for your motor to arrive.
What About Replacement Electric Motors Made To Special Requirements?
Laser printing and 3D printing also make it possible to build replacement motors exactly to your specifications. If your motor is a little unusual and you’re having trouble finding the perfect replacement, talk to ARC Systems about building a custom motor. We’ve built motors for garages, hotels, warehouses, real estate and other major businesses, so we have a lot of experience in the industry.
Couldn’t You Just Buy A Discount Motor?
Now that it’s cheaper than ever to buy replacement motors, you might have wondered if you can just buy a cheap motor and be done with it. However, there’s a difference between a bargain motor made from cheap materials and a high-quality motor made with some of the world’s most advanced 3D printers. A poor freight motor won’t last long–and in a worst-case scenario, it could cause a workplace accident.
When you need to get custom engineered replacement electric motors, contact ARC Systems to see what we can do for you. We sell custom motors as well as premade motors that replace most of the major models. If you have specific needs, we can build motors that are waterproof, fireproof, explosion-proof and suitable for full water submersion.
What About Obsolete Motors?
Since we can make custom motors, we also craft obsolete motors that manufacturers don’t produce anymore. Contact us today to see what we can do for your business.
What are the selection criteria for choosing an electric motor ?
Electric motors make it possible to perform different types of movement: fast, precise, continuous, with or without gear shifting, etc. All of these applications require their own motor technology.
First, you must choose between three main groups of electric motor :
1. The AC asynchronous motor (single-phase or three-phase)
2. The synchronous motor: DC motor (direct current), brushless, etc.
3. The stepper motor
In order to choose between these three groups, it is necessary to determine the type of application required as this will influence your choice:
If you want your motor to run continuously and with few gear changes, you should choose an asynchronous motor.
For dynamic applications, it is essential to have a synchronous motor.
Lastly, if you require precise positioning you should choose a stepper motor.
Depending on the movement you require, you will also need to determine the technical specifications and size of the motor:
To determine the technical specifications, it will be necessary to determine the power, torque and speed of the motor.
In order to determine the size, you must know how much space the motor will take up and how it is mounted (i.e.how it will be fixed in the system).
When choosing the dimensions and solidity of the motor you must also take into account the industrial environment that the motor will operate in:
There is a format adapted for every type of environment (explosive, damp, corrosive, high temperature, etc.)
For harsh environments there are motors with reinforced, waterproof, shock-resistant or dirt-resistant casings.
Finally, in recent years, energy efficiency has become an important factor to take into account when choosing a motor:
An electric motor that uses less energy will have a low energy impact, which will reduce its energy cost.
What are the energy efficiency standards for electric motor ?
Manufacturers are increasingly contemplating the question of energy efficiency. A greener and more environmentally friendly economy is one of the objectives of the 2015 United Nations Climate Change Conference which many States committed to. But it is above all in order to limit consumption and for savings that industry has been acquiring more energy-efficient equipment in recent years.
According to a study by the European Commission, motors account for 65% of industrial energy consumption in Europe. Taking action when it comes to motors is therefore an important step in order to reduce CO2 emissions. The Commission even predicts that it is possible to improve the energy efficiency of European-made motors by 20 to 30% by 2020. The result would be 63 million tonnes less CO2 in the atmosphere and 135 billion kWh saved.
If you also want to integrate energy-efficient motors and get savings while contributing to the planet, you will first need to look at the energy efficiency standards for motors in your country or geographical area. But be careful, these standards do not apply to all motors, only to asynchronous AC electric motors.
The International Electrotechnical Commission (IEC) has defined energy efficiency classes for electric motors placed on the market, known as the IE code, which are summarized in the international IEC standard
The IEC has identified four levels of energy efficiency that define a motor’s energy performance:
IE1 refers to STANDARD efficiency
IE2 refers to HIGH efficiency
IE3 refers to PREMIUM efficiency
IE4, still under study, promises SUPER PREMIUM efficiency
The IEC has also implemented the IEC 60034-2-1:2014 standard for testing electric motors. Many countries use national test standards, while also referring to the international IEC 60034-2-1 standard.
The EU has already adopted several directives aimed at reducing the energy consumption of motors, including the obligation for manufacturers to place energy-efficient motors on the market:
ClassIE2 has therefore been mandatory for all motors since 2011
ClassIE3 has been mandatory since January 2015 for motors with a power of 7.5 to 375 kW (or IE2 if these motors have a frequency inverter)
Class IE3 has been mandatory since January 2017 for motors with a power of 0.75 to 375 kW (or IE2 if these motors have a frequency inverter)
In the United States
In the United States, the standards defined by the American association NEMA (National Electrical Manufacturers Association) are in force. Since 2007, the minimum level required has been set at IE2.
The same classification applies to Australia and New Zealand.
Japan has harmonized its national regulations with IEC efficiency classes and included IE2 and IE3 electric motors in its Top Runner program in 2014. Introduced in 1999, the Top Runner program forces Japanese manufacturers to constantly offer new models on the market that are more energy efficient than previous generations, thus forcing emulation and energy innovation.
India has had a comparative efficiency label since 2009 and a national standard at an IE2 level since 2012.
