Calculations direct current
Performance: P = V X I
Performance: P = I² x R
Power output: P = V² / R
Mechanical 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
Active power factor: cos φ = P / S
Reactive power factor: sin φ = Q / S
Calculations three-phase current
Apparent power: S = V x I x √3
Active power: P = V x I x cos φ x √3
Reactiv power: Q = V x I x sin φ x √3
Active power factor: cos φ = P / S
Reactive power factor: sin φ = Q / S
Calculations cable cross-section
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 Δu x V)
Three-phase: A = (√3 x I x L x cosφ) / (K x Δv x V)
Calculations Torque
Torque: Md = 9550 x P / n
Calculations Slip
Slip: S = (Ns - N) / Ns * 100%
