SD 500™ Severe Duty AC Traction Drive
Magnetek designed the SD500 specifically
for use in higher performance electric
or hybrid cars, buses, delivery vehicles
and mining equipment.
Magnetek's
SD500, Severe Duty AC Traction Drive
design is based on a proven line of
state-of-the-art industrial controllers.
The drive can be connected to either a
permanent magnet or induction AC motor.
This combination of AC motor and
controller is the best choice for high
system efficiency at a wide range of
motor speeds. It also can be used on the
series or parallel hybrid scheme that
includes a generator. Magnetek has been
successfully providing SD500 traction
drives for commercial applications since
1997.
