How much does motor rewinding cost? (US ballpark ranges)
Most US shops quote electric motor rewinding cost after inspection, but buyers still need orientation before they call. Typical full-rewind ballparks run from about $250 to $900+ on fractional HP motors, $900 to $9,000+ in the 5 to 50 HP band, and $6,000 to $60,000+ for large industrial or medium-voltage work. Use these bands for budgeting, not as a guarantee. Currency, region, and motor condition change outcomes. Always insist on a written quote after inspection.
- Small motors (fractional to ~5 HP): Many repairs and rewinds fall from the low hundreds to about $1,000+, depending on rewind depth and parts.
- Medium motors (~5 to 50 HP): Common to see roughly $1,000 through several thousand for rewind-level work or major repairs.
- Large industrial (50 HP and up): Often several thousand to tens of thousands for full rewinds, extensive mechanical work, or critical spares with tight schedules. See our industrial motor repair guide for plant-focused service types and shop selection.
Comparing two or three quotes from shops you trust is still the best way to understand fair market price for your motor. Our how to choose a motor repair shop guide lists questions to ask so you compare apples to apples.

| 100 to 200 HP | $800 to $1,500 | $4,000 to $8,000 | $3,500 to $6,000 | +25 to 50% |
| 200 to 500 HP | $1,200 to $3,000 | $7,000 to $20,000 | $6,000 to $15,000 | +25 to 50% |
| 500+ HP | $2,000+ | Quote individually | Quote individually | Negotiated |
Note: High-voltage motors above 4kV require form-wound coil construction and are priced individually regardless of HP. Generator rewinding is priced separately. See the generator rewinding cost guide.
What affects motor repair and rewinding cost
- Motor horsepower
- HP is the primary cost driver. A 5 HP single-phase motor rewind costs $400 to $700. The same job on a 100 HP three-phase motor costs $2,500 to $5,000. Larger motors require more copper wire, more labor hours, and longer cure cycles in the impregnation oven.
- Voltage class
- Motors above 600V (medium voltage) require form-wound coil construction rather than random-wound winding. Form-wound rewinds cost 2 to 4x more than random-wound equivalents at the same HP because coils must be individually formed, insulated, and installed rather than machine-wound.
- Failure type and scope
- Bearing replacement is the least expensive repair ($150 to $1,500 depending on frame size). A full rewind, where all copper winding must be stripped and replaced, costs significantly more. Partial winding repairs (single-phase winding on a two-speed motor, for example) are typically priced between these extremes.
- Emergency vs standard turnaround
- Standard turnaround is 5 to 10 business days for most motors under 200 HP. Emergency turnaround (24 to 72 hours) carries a premium of 25 to 50% above standard rates due to overtime labor, expedited parts sourcing, and priority queue scheduling.
- EASA AR100 compliance
- Shops that follow EASA AR100 rewind standards perform core loss testing before and after stator burnout. This adds time and cost but preserves motor efficiency, the EASA/AEMT Rewind Study found no measurable efficiency loss on motors rewound to these standards. Rewinds from non-EASA-compliant shops may cost less upfront but risk efficiency degradation and early re-failure.
- Freight and logistics
- Motors that cannot be transported locally must be shipped to a repair facility. Freight costs for motors under 500 lbs typically run $150 to $400 for ground shipping. Motors above 500 lbs require flatbed or LTL freight, $300 to $800 or more depending on distance. Many shops in the IQMotorBase directory offer pickup and delivery within their service region.
What affects the cost of motor repair and rewinding?
No two jobs are identical. Qualified shops price from nameplate data, inspection, and scope of work. Understanding the drivers below helps you read a quote and budget realistically, whether you need a minor repair or a full rewind.
Motor size and horsepower (HP / kW)
Larger motors use more copper, insulation, and bench time. Small fractional-HP units may be a few hundred dollars to service; large industrial machines (for example 500 HP and up) routinely reach thousands to tens of thousands for a full rewind. Frame size, core length, and kW rating usually move the number more than brand alone.
Repair vs. rewind scope
Bearing replacement, cleaning, balancing, or targeted electrical work typically costs less than stripping and rewinding with new wire, insulation system, varnish or VPI, and full electrical testing. If you are unsure which path fits, see when to repair or replace a motor and types of repair services.
Condition and hidden damage
Burned slots, damaged laminations, bad fits, or contamination add labor and parts. Reputable shops often quote after tear-down so the estimate matches reality. Ask what happens if additional damage is found.
Voltage, enclosure, and motor type
High voltage, explosion-proof, washdown, vertical, DC, or custom designs can require different materials, processes, and compliance checks, all reflected in price. Single-phase vs. three-phase and specialty windings also change labor hours.
Labor, parts, testing, and turnaround
Regional labor rates, OEM vs. aftermarket parts, and included tests (megger, surge, hi-pot, balancing) vary by shop. Emergency or rush work often carries a premium. Align expectations up front: what is included, what is extra, and typical lead time.

Frequently asked questions
- How much does it cost to rewind an electric motor?
- There is no single price. Small fractional-HP motors often run from a few hundred dollars up to roughly $1,000+ for a full rewind; medium motors (about 5 to 50 HP) commonly fall in the low thousands to several thousand; large industrial units (50+ HP) can reach tens of thousands. The only reliable number is a written quote after inspection.
- Is rewinding cheaper than buying a new motor?
- Sometimes yes, especially for large or long-lead specialty motors, but not always. Compare the rewind quote to replacement cost, downtime, and efficiency. Use a structured repair vs. replace comparison (such as the IQMotorBase.com guide on when to repair or replace an electric motor) to decide when each option makes economic sense.
- Why do motor repair quotes vary between shops?
- Shops differ in labor rates, material sources, testing included, warranty terms, and how they scope hidden damage. Always compare line items (labor, materials, testing, rush fees) and ask what is included. A practical checklist for vetting shops is available on IQMotorBase.com under how to choose an electric motor repair shop.
- What is usually included in a motor repair or rewind quote?
- A good quote should spell out scope: inspection findings, labor, wire and insulation class, bearings or other parts, varnish or dip, balancing, and electrical tests (e.g. megger, surge, optional load test). Emergency or expedited work is often priced separately.
- How can I get an accurate motor rewind cost estimate?
- Send photos, nameplate data (HP/kW, voltage, frame, RPM), and failure symptoms, but expect the final price after physical inspection. Use IQMotorBase.com to request quotes or browse repair shops by location and contact shops directly.
- What happens to the information I submit in quote requests?
- Contact and motor details are used to route your request and support quote follow-up between you and relevant repair shops. Information is handled for service delivery and communication, not sold as a standalone contact database.
- What is the difference between motor repair cost and motor rewinding cost?
- Motor repair cost is a broad term: it can mean bearings, seals, cleaning, balancing, or partial electrical work. Motor rewinding cost usually refers to stripping the stator (or armature), replacing magnet wire and insulation, re-varnishing or VPI, assembly, and full electrical test. Rewinds are typically the largest line item when burn-down or insulation failure is involved.
- How much does AC motor rewinding cost compared to DC motor repair?
- Both are quoted from inspection. AC induction rewinds are common; pricing scales with copper, slots, and HP. DC motors add commutator, brush rig, and armature work, repairs and rewinds can be labor-heavy. Always compare apples-to-apples scope (armature vs stator only, field coils, mechanical fits) on the written estimate.
- Do shops charge a minimum or bench fee for small motor repair?
- Yes, many US shops apply a minimum labor or bench charge for fractional-HP and small jobs because setup, teardown, and documentation time does not shrink with motor size. That is why small motor repair cost can look high relative to the copper value alone, ask how minimums apply before authorizing work.
- Does emergency or after-hours motor repair cost more?
- Usually yes. Rush diagnostics, overtime labor, expedited materials, and weekend or holiday callouts are often billed at a premium. If uptime is costly, discuss expedite pricing and parallel paths (loaner, spare, swap) up front, see IQMotorBase.com emergency motor repair guidance.
- Is motor rewinding worth it for energy efficiency or upgrading to inverter duty?
- Rewinding can restore reliability, but efficiency rules depend on duty, hours run, utility rates, and incentives. Inverter-duty upgrades, insulation class changes, or VPI may add cost but reduce future failure risk. Compare total cost of ownership against a new premium-efficiency motor using real quotes and payback math.
- Can ChatGPT or an online calculator replace a shop quote for motor rewinding?
- No. AI assistants and calculators are useful for vocabulary, checklists, and ballpark budgeting. They cannot see slot damage, lamination condition, or bearing fits. Use this page’s calculator and tables for orientation, then obtain written quotes after inspection from qualified motor repair shops.
