Electricity Monitoring Software & Meter (option):
supplied with all SunPower™ products for monitoring & analysing real
time energy Savings.
Operational Principles
The inefficiency of an AC induction motors worsens when the workload
of a motor is less than full. When the actual work load of the motor
is lower than the rated load, the sensing circuit reduce the energy
being fed to the motor to the exact ampare level the motor needs. This
has the effect of reducing motor consumption.
SunPower™ Motor Saver controls the AC induction
motor so it always functions at its optimum efficiency. The Motor Saver
reduces excessive energy waste in three-phase AC induction motors. The
controller unit is providing a reduced ampares loss, reduced energy
consumption and improved power factor.
The unit monitors the phase lag of the current and voltage
relationship in a motor that is operating at less than full mechanical
load. The SunPower™ Motor Saver controller cuts back
the ampares to precisely what the motor requires to maintain the same
rated speed and torque under the present load.
Reduces Electric power consumption 10% to 48%.

Through its SunPower™ Motor Saver, Conservelec is
helping companies save electricity on equipment and appliances driven by
three-phase AC induction motors, thus strengthening competitiveness.
Motor Saver reduces energy waste in AC induction motors and makes the
motor function at its optimal efficiency in proportion to load rate.
Motor Saver monitors the phase lag of the current and voltage
relationship in a motor that is operating at less than full mechanical
load. Motor Saver cuts back the voltage to precisely what the motor
requires maintaining the rated speed and torque under the present load,
thus reducing power consumption.
By reducing power consumption, SunPower™ Motor Saver reduces the need of constructing pollution-generating,
resource-consuming power plants and contributes to making clean world.
Motor Saver is an auxiliary equipment designed to control input
voltage of motor while not disturbing the production rate. Continuous
dynamic control is applied to the motor by a microprocessor which calls
Thyristor. Thyristor phase control is used to adjust the motor terminal
voltage in respond to changes of motor loading. Plug N Save uses micro
controller 8 bit at 20 MHz as CPU (central processing unit) to respond
the load change within 1/100 second.
Motor Saver working in 2 continuous action:
Limit the input current and torque to control accelertion and
deceleration of motor, referring to soft start & soft stop.
Automatically adjust voltage supplied to the motor in correspond
to the load changes, this may call Dynamic Optimization to the highest
speed of motor.
