Mistakes I Still See Other Teams Make
Here's the thing: most motor purchases go one of two ways. Someone picks the cheapest quote, or someone reorders the same motor that's been running for ten years. Both approaches burn money.
This checklist is for anyone who specifies, procures, or approves industrial motors. I've been on the buying side for 6 years, managing a motor-and-spares budget of roughly $45,000 a year. In that time, I've approved about 140 motor-related POs and tracked every one in our cost system. These 7 steps cut our motor-related spend by 18% without hurting reliability. You can apply them as-is.
Step 1: Write the Application Profile Before You Look at Prices
The most common error is pulling the old part number and reordering without checking what the motor actually does. We had a pump motor fail twice in a year. The floor guys said "just order another ABB motor." When we audited the application, it turned out the motor was oversized by 40%—it ran below its efficient band, and the bearings took the abuse.
Before you even request a quote, write down:
- Duty cycle: continuous, intermittent, or short-time?
- Starting torque: direct-on-line, soft-start, or VFD?
- Environment: washdown, dust, hazardous area classification?
- Power supply: voltage, phase, frequency at the install location
Checkpoint: if you can't write a one-paragraph application profile, you aren't ready to order.
Step 2: Compare Efficiency Classes, Not Just the Sticker Price
The second thing that companies get wrong: prioritizing the purchase price over efficiency class. An ABB IE3 motor—or NEMA Premium, as it's labeled in the U.S.—costs more upfront than an old IE1-class motor. But if the motor runs 4,000+ hours a year, the payback is usually under a year.
Real numbers from our site. We replaced 14 motors in 2023. The IE3 versions cost $450 more each—$6,300 total. Our energy monitoring showed consumption dropped by 6,400 kWh per motor per year. At $0.12/kWh, that's $770 per motor, per year. Payback: 7 months. When I compared our 2022 and 2023 line-item data side by side—same equipment, different efficiency class—I finally saw how much we'd been leaving on the table.
By the way: the "ABB Baldor motor" listings you'll see from U.S. distributors are the same engineering. ABB acquired Baldor in 2011 and kept the brand on certain lines. What matters is the spec sheet, not the badge.
Checkpoint: calculate annual energy cost for each option using your actual run hours and your blended electricity rate. Not a national average.
Step 3: Calculate Total Cost of Ownership, Not Just the Quote
People assume the lowest quote means the vendor is more efficient. What they don't see is which costs are hidden or deferred. I compared five vendors for 48 motors a couple of years back. The low quote was $37,000. The one I approved was $41,200. Here's what the cheap vendor's quote excluded: freight on 48 motors (motor freight isn't cheap), a $150 account setup fee, and the shaft grounding rings we'd specified. That vendor also quoted the base 12-month warranty; our standard is 36 months. We paid the $4,200 difference to get the warranty we needed.
Since then, I built a TCO spreadsheet, and every motor purchase gets line items for delivery, installation support, warranty escalation, commissioning spares, and disposal of the old unit. (Should mention: a "free setup" offer from another vendor once cost us $450 more in third-party billing. Free usually means it's buried somewhere.)
Put it in writing: your PO should list every TCO line item, not just the unit price.
Step 4: Ask Whether You Even Need a Motor
This sounds basic, but I'm serious. We audited a sample of our motor requests and found about 7% were better solved with a different motion product.
- Need precise positioning of a small load? A NEMA 17 stepper motor costs $20–80 and gives repeatable position control. Putting a 5 HP induction motor on a two-axis positioning rig is a waste of money and floor space.
- Need short linear strokes under constant load? Small electric actuators often beat a motor-plus-gearbox-plus-pneumatic-cylinder setup on total installed cost. No air lines, no filters, fewer failure points.
- Need constant-speed drive only? A standard AC motor is fine. A VFD pays for itself only when you actually need speed control or soft starting.
The reverse happens too. We had an engineer try to force a NEMA 17 stepper into a 20:1 speed-range continuous-duty application. That motor didn't last a full shift. Use the right tool.
Checkpoint: document why you chose the motor category before you specify a part number.
Step 5: Specify Bearings Explicitly
Every now and then an engineer asks me, "What's a ball bearing got to do with buying a motor?" Fair question. A ball bearing is the component that lets the rotor spin with low friction while supporting the shaft load. In an industrial motor, bearings are the single most common failure point. I went through our work orders last year: 23 motor failures in 4 years, 19 of them bearing-related.
- Bearing grade and type—ABEC/REC class matters for high-speed runs
- Regreasable vs. sealed: for continuous duty, you want regreasable bearings with a grease port
- Shielded vs. sealed: depends on contamination in the environment
- OEM fitting: standard ABB motors are fine in clean service; their severe-duty lines carry higher-grade bearings. If your plant is dusty or humid, pay for the upgrade.
Checkpoint: bearing spec written into the PO, not left to "whatever the factory puts in."
Step 6: Evaluate Lead Time Against Your Downtime Cost
A vendor quoted me $3,200 on an ABB motor but couldn't ship for 14 weeks. A different vendor had the same motor at $3,550 with 3-day delivery. If I'd gone with the cheap quote, our line would've sat down for an extra 11 weeks. Our downtime is roughly $8,000 a day. The math wasn't close.
The "local is always faster" thinking comes from an era before modern logistics. Today, a well-organized remote vendor can beat a local one on price and lead time. But I also check whether they actually stock the unit or ship it from a central warehouse. "14 weeks" from a distributor without stock is just a delayed surprise.
In Q2 2024, when we switched vendors for a critical line, we also put support clauses into the contract—response time, after-hours coverage, restocking terms. It costs nothing to ask for them.
The real check: what does your plant lose per day of downtime? If you don't know that number, find out. It changes procurement decisions fast.
Step 7: Save Everything Before You Approve the PO
This step is the one most people skip, and it's the one I'm most insistent about. When a motor arrives, you should have on file:
- The full datasheet, or a link to it
- Bearing part numbers—so nobody has to disassemble the motor to identify them later
- Seal type and part number
- Wiring diagram, including VFD settings if it's on a drive
- Purchase date, warranty expiry, vendor service contact
We created a folder per motor line in our ERP. When maintenance needs a replacement bearing, they find it in two minutes instead of wrenching the motor apart on the floor. Five minutes of filing on purchase day saves hours of downtime later.
Sign-off checkpoint: add "documentation saved" to your PO workflow.
Mistakes I Still See Other Teams Make
- Buying an "ABB motor" from a non-authorized seller at a tempting price. If the seller isn't authorized, the warranty is typically void—and the unit may be gray-market or reconditioned. ABB's distributor locator takes 20 seconds to check.
- Forgetting the shaft grounding ring on VFD-fed motors. VFDs create shaft voltages that slowly destroy bearings. A grounding ring costs $30–60. A bearing replacement, $200–800. You do the math.
- Ordering by frame size alone. NEMA 182T and IEC 132M don't necessarily line up—shaft dimensions, foot mounting, terminal box position all differ. Specify the ABB motor type, frame, and electrical data together.
- Ignoring the insulation class on the nameplate. If the plant runs hot—near a furnace, outdoor summer install—upgrading from Class F to Class H insulation is cheap insurance.
Prices as of January 2025; verify current rates before ordering. This is a procurement checklist, not engineering guidance—have a qualified engineer confirm the application before you approve.
