Initial release of MotorMate - electric motor calculator and wiring guide.
Electric motor calculator for RPM, poles, FLA current, HP to kW, and capacitors
MotorMate is a complete electric motor calculation and reference toolbox designed for electrical engineers, industrial technicians, maintenance professionals, and apprentices. Whether troubleshooting on the plant floor or sizing equipment in the workshop, MotorMate delivers fast, reliable calculations and technical reference data right at your fingertips. CORE CALCULATORS - Synchronous Speed & RPM: Calculate theoretical motor RPM from line frequency and number of poles. - Pole Count: Determine standard motor pole configurations based on line frequency and measured shaft RPM. - Frequency: Calculate required inverter or line frequency to achieve target synchronous speeds. - Power Conversion: Instantly convert between mechanical horsepower (HP) and kilowatts (kW) with precision. - Full-Load Amps (FLA): Calculate full-load current for single-phase and three-phase AC induction motors based on voltage, power factor, and efficiency. - Capacitor Sizing: Estimate run capacitor and starting capacitor capacitance in microfarads (uF) using line voltage and winding current. MOTOR PROFILES & EQUIPMENT TRACKING - Save motor nameplate details including rated horsepower, voltage, full-load amps, RPM, frame size, and enclosure type. - Keep track of thermal ratings, service factors, wiring configurations, and field service notes. - Tag favorite motors for instant access when performing recurring maintenance or measurements. CALCULATION HISTORY - Automatic logging of calculation results with date and timestamp grouping. - Filter past records by specific motor profile or calculation type. - Save critical calculations and reload inputs directly back into any calculator. TECHNICAL REFERENCE LIBRARY - 18 comprehensive technical reference guides covering essential motor theory and practical field work. - Clear wiring diagrams for single-phase and three-phase motor lead connections. - In-depth guides for motor starters, dual-voltage configurations, nameplate decoding, power factor correction, and troubleshooting common motor faults. BUILT FOR FIELD WORK - Clean, intuitive interface optimized for quick input and high-contrast readability. - Instant calculations update dynamically as you adjust parameters. - Designed for industrial maintenance, HVAC-R technicians, rewind shops, and electrical contractors.
