Motor Rewinding Calculator

Motor Rewinding Calculator is a professional workshop companion engineered for electrical technicians, motor rewinders, repair shops, and electrical engineering students. Design, verify, and document AC induction motor stator windings with precision and speed.

CALCULATE COMPLETE STATOR WINDINGS
Enter core nameplate and stator parameters to instantly determine key electrical and physical winding values:
- Series turns per phase and total coils
- Coils per phase and coil grouping distribution
- Coil pitch and slot span layout recommendations
- Estimated wire length per phase and total conductor requirements
- Phase resistance at 20°C for copper magnet wire
- Voltage-based connection type recommendations (Star or Delta)
- Synchronous motor speed based on pole configuration
- Estimated full-load line current and conductor cross-sectional area
- Parallel strand recommendations for heavy-gauge windings

MANAGE WORKSHOP REWIND PROJECTS
Keep all job documentation organized in one structured workspace:
- Create dedicated rewind projects with asset tags and serial numbers
- Log motor nameplate ratings, manufacturers, models, and customer details
- Attach stator measurements, bore dimensions, core length, and slot depths
- Track repair progress across standard overhaul stages
- Document motor condition with workshop inspection photos and technical notes

TECHNICAL REFERENCE LIBRARY
Access essential technical references directly at your workbench:
- Standard AWG and metric magnet wire gauge tables with bare and insulated diameters
- Winding patterns, concentric versus distributed layouts, and connection diagrams
- Stator diagnostics, insulation class ratings, temperature limits, and surge test guides
- Comprehensive motor troubleshooting glossary and standard electrical formulas

BUILT FOR FIELD WORK AND WORKSHOPS
Engineered with clear high-contrast typography, input validation, and instant recalculation, Motor Rewinding Calculator streamlines your winding diagnostics from initial teardown to final testing.
