Symbol explanation

PM	: Motor shaft output for load (kW)

η: Motor efficiency (normally, approx. 0.85)

: Motor power factor (normally, approx. 0.75)

: Motor rated voltage(V)

: Motor rated current(A), for commercial power

k: Correction factor calculated from current distortion factor (1.05 - 1.1, depending on PWM method)

: Continuous motor capacity (kVA) PC1=KPMnT/ηcos

: Starting current/rated current of motor

: Number of motors in parallel

: Number of simultaneously started motors

: Total inertia (GD2) calculated back to motor shaft (kg m2)

: Load torque

: Motor acceleration time

N : Motor speed
