With the changes to efficiency motor minimum energy performance levels stipluated in AS1359.2004, SEW-EURODRIVE offers innovative
high energy-efficient motors. Unlike conventional AC motors with aluminum die-cast rotor, they use a copper die-cast rotor
with a high conductance and lower losses.
Not only do the new energy-efficient motors significantly reduce the heat losses in the rotor, but they also limit additional
losses, raising the efficiency level of the motor. With the copper rotor technology the motor frame size for the power is
kept the same, and there is also the advantage of improved control characteristics when used with frequency inverters due
to a stiffer speed-torque characteristic curve.
Similar to the standard motors, the DTE and DVE motors can be combined with all gear units from the proven SEW-EURODRIVE modular
system that are matching and suitable with respect to power and torque while maintaining power and size to form gearmotors.
Naturally, the energy-efficient motors and gearmotors can be supplied in all mounting positions and design types and with
all options known from the standard series.
