| Abstract |
A standard configuration of an Adjustable Speed Drive (ASD) consists of two separate units: an AC
motor, which runs with fixed speed when it is supplied from a constant frequency grid voltage and a
frequency converter, which is used to provide the motor with variable voltage-variable frequency
needed to adjust the speed of the motor. The integrated motor drive concept is a result of merging the
two units in order to achieve the following benefits [1]-[3]: reducing the design and the
commissioning time in complex industrial equipments, no need for a cabinet to host the frequency
converter, no need for shielded cables to reduce RFI, no need for cables for the speed transducers or
for other sensors for industrial process control (e.g. pressure). This solution is currently available up to
7.5 kW being not used in the medium and high power range due to a low-density integration of the
converter caused by the large size of the passive components (electrolytic capacitors and iron chokes)
and vibration of the converter enclosure. |
