RPM = 120 f / poles with strict frequency unit handling.
Theoretical synchronous speed: RPM = 120 × f / poles (60 Hz mains example: 4-pole ≈ 1800 RPM nominal sync).
- Frequency used50 Hz
- Synchronous speed1,500 RPM
AC Motor Synchronous Speed Calculator helps you rpm = 120 f / poles with strict frequency unit handling. It is commonly used by domain specialists, operations teams, learners for synchronous speed, ac motor rpm, pole count.
