Motor Torque-Speed Calculator

Calculate motor torque T = P/(2πN/60), speed in RPM from frequency and pole pairs n = 60f/p (synchronous speed). Slip s = (n_s - n)/n_s for induction motors. Torque-speed curve analysis for motor selection.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)

How It Works

Calculate motor torque T = P/(2πN/60), speed in RPM from frequency and pole pairs n = 60f/p (synchronous speed). Slip s = (n_s - n)/n_s for induction motors. Torque-speed curve analysis for motor selection

Each component has a specific meaning:

  • Frequency — The frequency recorded for the patient or scenario being assessed.
  • Pole pairs n = 60f/p — The pole pairs n = 60f/p recorded for the patient or scenario being assessed.

Note: Interpret the motor torque-speed result against the clinical thresholds and context described above.

How to Use

Enter the frequency, pole pairs n = 60f/p for the patient or scenario you are assessing. Calculate motor torque T = P/(2πN/60), speed in RPM from frequency and pole pairs n = 60f/p (synchronous speed). Slip s = (n_s - n)/n_s for induction motors. Torque-speed curve analysis for motor selection. Use the motor torque-speed result to inform your clinical assessment.
