Calculations direct current
  • Active power: P = V x I
  • Active power: P = I² x R
  • Active power: P = V² / R
  • Mecanical power: P = W / t
Calculations alternating current
  • Apparent power: S = V x I
  • Active power: P = V x I x cos φ
  • Reactive power: Q = V x I x sin φ
  • Aktive power factor: cos φ = P / S
  • Reactive power factor: sin φ = Q / S
Calculations three-phase
  • Apparent power: S = V x I x √3
  • Active power: P = V x I x cos φ x √3
  • Reactive power: Q = V x I x sin φ x √3
  • Active power factor: cos φ = P / S
  • Reactive power factor: sin φ = Q / S
Cable cross-section calculations
  • Direct-current: A = (2 x I x L) / (K x Δv x V)
  • Single-phase: A = (2 x I x L x cosφ) / (K x Δv x V)
  • Three-phase: A = (√3 x I x L x cosφ) / (K x Δv x V)
Torque calculations
  • Torque: Md = 9550 x P / n
Slip calculations
  • Slip: S = (Ns - N) / Ns x 100%
Energy saving calculator
  • Energy Saving Calculator
Ohm's law
  • Voltage: V = I x R
