Energy costs are a major part of industrial operating budgets. While new motors often offer improved efficiency, a correctly executed rewind can restore or even improve a motor's performance by using modern insulating materials and optimized winding techniques.
Key factors include winding accuracy, insulation quality, rotor balance and bearing condition. A sloppy rewind risks reducing efficiency — but a professional rewind can use superior materials and tighter tolerances for better results.
Compare the total cost of ownership: purchase cost, downtime, installation and disposal for a new motor versus the rewind cost, service lifespan and energy consumption for a refurbished motor. Often, rewinding is the more economical choice for larger motors.
Rewinding retains existing materials and avoids the embodied carbon of manufacturing and shipping a new motor. For businesses committed to net-zero targets, choosing rewinds where possible aligns with circular economy principles.
