ABB Motors: What I've Learned Ordering Them for 15 Years

I've been the one who orders our ABB motors since 2015. Not the engineer who specs them—the person who actually does the buying. So I've learned a few things the catalog won't tell you. If you've ever had a rush order go sideways, you know that feeling. Let me save you the headache.

The Part Nobody Warns You About

From the outside, buying an ABB motor online looks simple. Find the part number, compare prices, hit order. The reality is a bit messier. The cheapest listing might not include the flange, or the shaft key, or the terminal box position you need. And back-ordered motors can disappear from inventory with no warning.

Back in 2022, I found a price for an ABB motor that was about 20% below our usual distributor. Looked perfect. Same frame size, same kW rating. What I didn't catch was that it was the wrong mounting arrangement. The engineer caught it when the motor arrived—wrong bolt pattern for our gearbox. Return shipping and restocking fee ate up most of the savings. Let's just say the "bargain" ended up costing about $90 more than our regular supplier would have charged.

What 'ABB Motor Online' Actually Means

Here's what you need to know when you're searching for ABB motors online: not every seller is an authorized distributor. Some are brokers. They don't hold inventory—they find a motor after you order it. That's fine if you have lead time. It's a problem if you need the motor in two weeks.

Our company ran into this in 2023. We ordered three ABB induction motors from a site that looked official. Two showed up in four days. The third took six weeks because the broker was waiting on a shipment from overseas. The production line wasn't down, but we had to pay overtime to get another line reconfigured. In my experience, it's worth paying a small premium for a distributor with actual stock.

AC Motor Speed Control Isn't Optional Anymore

If you're still running AC motors at fixed speed, you're probably leaving money on the table. ABB's variable frequency drives (VFDs) are a big part of why people look for ABB motors in the first place. The motor and the drive are designed to work together.

I'm not an engineer, so I'll keep this simple. A VFD controls the motor speed by varying the frequency of the power going to it. That means you can run a conveyor at 80% speed when you don't need full throughput. The energy savings add up. In our facility, we cut motor energy use by about 15% after adding VFDs to three ventilation fans (based on data from our utility meter, 2023).

One thing to watch: not all motors are suitable for VFD operation. Inverter-duty motors have better insulation to handle the voltage spikes VFDs produce. ABB makes this pretty clear in their product documentation, but if you're buying a third-party motor, check the datasheet. The wrong combo could mean motor failure in a year or two.

ABB Servo Motor Repair: When It Makes Sense

Servo motors are a different beast than standard induction motors. They're more expensive, more precise, and when they fail, the repair decision isn't always obvious.

I'll be honest: I've had mixed experience with third-party servo repair shops. ABB servo motor repair is a specialized skill. Some independent shops do great work. Others are basically guessers with a soldering iron. In 2021, we sent a servo motor to a "certified" shop that wasn't actually authorized by ABB. It came back working, but it was misaligned and had a vibration issue. We ended up sending it to ABB's repair center and it cost us double—the initial repair plus the correct one.

Here's my rule of thumb now: if the servo motor is still under the ABB warranty, send it back to ABB. If it's older and out of warranty, a reputable independent shop might be fine—but ask for references from companies in your industry. And get the repair report in writing. If they can't tell you what was wrong and what they replaced, that's a red flag.

What a Stepper Motor Is (And Isn't)

When people search "what stepper motor," they often stumble onto ABB's product pages. ABB doesn't make traditional stepper motors, by the way—they're more known for servo motors and integrated drives. But understanding the difference helps you know which one you need.

A stepper motor moves in discrete steps. You send it a pulse, it rotates a set amount—like 1.8 degrees. It's simple, relatively cheap, and works great for positioning tasks that don't need extreme speed or feedback. Think 3D printers, small CNC machines, camera gimbals.

A servo motor, on the other hand, uses an encoder to continuously monitor its position. It can accelerate faster, hold torque better, and is generally more accurate. It's also more complex to set up. For industrial automation, servo is usually the right answer when you need precise speed or position control.

From my purchasing perspective, the cost difference is significant. Steppers might be a few hundred dollars; servos can be over a thousand depending on the system. If you're an OEM designer reading this, don't spec a servo where a stepper would work. But don't try to make a stepper do a servo's job either—I've seen that fail on a packaging line, and the retrofit cost more than just buying the right motor initially.

My Unpopular Opinion: Don't Always Buy the Cheapest ABB Motor

I recommend ABB motors in most cases, but there are situations where they're overkill. If you're replacing a motor for a non-critical application with low duty cycle—maybe a small pump that runs occasionally—a standard ABB induction motor is fine. But if you're building a high-performance motion control system, investing in a servo or synchronous reluctance motor makes sense.

A lot of buyers search for the lowest price and then complain about reliability. I've learned to look at total cost: the motor, the drive, the installation, and the expected lifespan. I've also learned that ABB's online tool—you can find it through ABB's website—helps narrow down the exact motor for your specs. Using that beats guessing.

According to ABB's published warranty terms, motors have a standard warranty period, but you need to verify the conditions—some warranties are voided if the motor isn't installed by a qualified technician (Source: ABB Motors and Generators documentation, 2025; verify current terms). That's not ABB being difficult. That's every serious manufacturer.

One Last Tip on Ordering

Before you order an ABB motor online, confirm three things with the supplier:

• Stock availability: Is it in stock, or will it be shipped from a warehouse? Get a number.
• Lead time: Ask for a delivery date in writing, not just "a few weeks."
• Return policy: If the motor arrives damaged or is the wrong frame, will they cover return shipping?

I've learned this the hard way. In 2020, a supplier promised "7-10 business days" and it took six weeks. Our electrician had already scheduled installation around that timeframe—which meant paying him for a day of no work. That's the kind of cost that doesn't show up on the invoice.

So here's my honest take: ABB motors are solid. But the buying experience depends on the supplier. Find one that answers the phone, knows the product, and doesn't just read from a catalog. That's worth more than a 5% discount.
