Š Measures to protect motors against surge voltages
In a system in which a 400V-class general-purpose motor is operated with a voltage PMW inverter
that uses an ultra high-speed switching device (such as an IGBT), surge voltages may be produced
and deteriorate the insulation of motor coils, depending on the cable length, wiring method, cable
constant, and so on. Here are some examples of measures against surge voltages.
(1) Use motors with a high dielectric strength.
(2) To suppress surge voltages, install an AC reactor (an input reactor may be used instead. For the
application, contact your Toshiba dealer) or a surge suppression filter on the output side of the
inverter.
