Success of Energy-Efficient Industrial Motor Leads to Expansion at Advantech
In January 2022, the company announced a multi-milliondollar
investment to expand and scale its facility in Florence,
Alabama due to increasing demand for the MaxEff motor and
related products. The 55,000 sq ft plant was opened in 2019.
" Adventech's demand from the market over the last 24 months
has been remarkable, " said CEO Ron Ballman. " Adventech is
committed to be the leading solutions provider in all segments
of the electric motor market. In March 2022, he announced that
the company was developing an EV version of the MaxEff.
Like other industrial electric motors, Adventech's
MaxEff motor features an induction motor circuit.
Unlike traditional models, however, it has a builtin,
all-in-one induction generator circuit that is
designed to use the same magnetic field, rotor,
and stator to produce more shaft power. With an
expansion of its manufacturing facility at Florence,
Alabama and new sales initiatives, now the
company is aiming to serve more segments of
the electric motor market.
The Maxeff circuit compensates the grid that
feeds it, eliminating wasted energy that can
occur with standard induction motors. Where a
standard motor would require a 200 kVA generator
to start, a comparable Maxeff will start on a
100 kVA generator.
The motor circuit is directly connected to power
and the generator circuit is 1800 phase out.
When the motor is connected direct online, the
motoring circuits come into action which draws
a lower current since it utilizes only 2/3rd of the
winding, limiting higher inrush current. Once the
generator circuit is excited, the motor comes into
a full circuit. At that point, the motor's speed is
increased which does not demand a high Inrush
current and still has higher locked rotor current.
Adventech reports that the motor has undergone
extensive third-party testing which confirms the
performance and validates the data that indicated
that the MaxEff motor not only generated
leading inductive power, but also had higher
torque and RPM's than conventional motors, all
while operating at a power factor of 1.
It couples the motor with its Adventview remote
monitoring system and MaxDrive variable
frequency drive system for maximizing energyefficient
operation. The remote monitoring system
provides vibration, temperature and power
consumption data directly to a smart device.
The drive system operates as any other variable
frequency drive but additionally can return power
from the MaxEff motor back to the facility grid.
