Approximate calculation of required motor terminal voltage for a specified motor speed (up to 3000rpm)
Ukl = 1,2 (EMC*n/1000 + I* (Rph + RL) (Volts)
where:
Ukl
Required motor voltage (V rms)
EMF
Back-EMF of motor (V rms)/1000 rpm
Rph
Resistance of motor (between terminals) (
Ω
)
RL
Line resistance of motor cable (
Ω
)
I
Motor-current (A rms)
