Product Brief
E-MAX motor is the special designed permanent magnet synchronous motor based on the IEC norm. E-MAX PMSM will be used for next generation which need more energy saving product. Exceed IE4 variable speed AC motor (IEC60034-30-2-2016).

E-MAX motor is the first generation of DBS EC motor. E-MAX has led to develop the next generation of technology in motor efficiency and performance.
E-MAX motor contain two series:
E-Max commercial
IEC Frame 71 to 90 permanent magnet synchronous motor integrated drive
E-Max Industrial
IEC Frame 71 to 132 permanent magnet synchronous motor

Efficiency class
E-MAX motor has ultra-high efficiency both at full load and light load. The flat efficiency curve can save more energy when the motor drive the fan or pump in HVAC field.
Compare to IE4 motor efficiency class E-MAX

E-Max Commercial series

** System efficiency include the motor and drive efficiency.

E-Max Industrial series

** Efficiency is only motor efficiency.

VFD consideration
PMSM must drive by the VSD. The motor cannot connect to the normal AC power directly. The VSD can be the commercial drive with vector control or PM motor control mode. VSD need to be set up the correct motor parameter (see below table). The detail parameters can be find in the model data sheet.

Power choose consideration
       The power and torque in above model list is the rated power or torque when the motor has not any cooling method (IC410). If the motor cooled by the wheel or the load the motor power can be larger. The detail running range please see detail model data sheet. Below chart is a sample to decide the power at different cooling condition.
