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) ()

RL Line resistance of motor cable ()

I Motor-current (A rms)
