  • Mechanical Speed = Electrical Speed * 2 / Stator Poles
  • Fundamental Frequency = Mechanical Speed * Stator Poles / 60

Convert between mechanical speed (RPM), electrical speed (eRPM), and fundamental frequency (Hz) for electrical motors with this versatile tool.

Enter the number of stator poles and one other value to calculate the other properties. This calculator helps align motor speed and frequency with application requirements, making it invaluable for motor setup and design.
