Inverter Control for Energy Saving
(1) Energy saving with speed control
The consumed power of a variable-torque load, such as fans, pumps,
and blowers, is proportional to the cube of its rotation speed.
This means that controlling the rotation speed to adjust the air
volume can lead to energy saving.

(3) To save more energy – the IPM motor control
High efficiency achieved with IPM motors
The IPM motors that have permanent magnets embedded in
their rotors are even more efficient than the high-performance
energy-saving motors.

Smooth replacement from a general-purpose
motor (with the same installation size)
The frame number of the MM-EFS is the same (same size) as
the Mitsubishi general-purpose motors (4-pole SF-JR/SF-HR
series). Replacement is easy as the installation sizes are
compatible.

(4) Check the energy saving e ect at a glance
Energy saving monitor is available. The energy saving effect can
be checked using an operation panel, output terminal (terminal
FM), or network.

(2) Energy saving with Optimum
excitation control
The optimum excitation control achieves the highest motor
efficiency. Further energy saving can be achieved for
applications such as fans and pumps with variable load torque.
