Vpwm
Purpose: to measure on pulse width modulated signals, like motor drive inverter outputs
Principle: readings show the effective voltage based on the average value of samples over a whole number of periods
of the fundamental frequency
Accuracy: as V
rms
for sinewave signals
V/Hz
Purpose: to show the measured Vpwm value (see Vpwm) divided by the fundamental frequency on Variable AC Motor
Speed drives.
Accuracy: % Vrms + % Hz
Note
AC motors are designed for use with a rotating magnetic field
of constant strength. This strength depends on the applied
voltage (Vpwm) divided by the fundamental frequency of the
applied voltage (Hz). The nominal Volt and Hz values are
shown on the motor type plate.
