HOW E-SAVE TECHNOLOGY WORKS
How E-Save Technology® Works
Electric motors operate efficiently when they are heavily loaded – meaning they efficiently translate electricity into work. But when motors are lightly loaded, they become very inefficient and waste electricity. This is where E-Save Technology comes in.
E-Save Technology saves energy on variably or lightly loaded motors that operating at a constant speed (full normal RPM). The technology does this by sensing the load on an AC induction motor by examining the phase lag between current and voltage.
When the actual workload of a motor is lower than its rating, the sensing circuits reduce the energy (voltage and current) being fed to the motor to the precise level the motor needs. This reduces motor energy consumption.
When the power factor increases with additional load, energy being fed to the motor increases instantly. As a result, the motor maintains its rated speed and torque under variable loads.
The motor efficiency controller enables AC induction motors serving constant speed/variable load applications to operate at peak efficiency at all times. Savings on energy costs are typically 20-40% because most motors work well below rated levels much of the time.
Motor Temperature & Motor Life
Motor life expectancy is directly dependent on operating temperature. Every 10°C rise in operating temperature reduces motor winding insulation life by one-half. Higher operating temperatures reduce bearing life as well, which can considerably shorten motor life expectancy.
