Electric motor efficiency system
Power Efficiency’s E-Save Technology provides energy savings in constant-speed motor applications and “cruise control” for a range of variable-load motors in government and commercial buildings. The system is suited for equipment such as escalators, and motor-generator sets on elevators and conveyors. The motor efficiency system can be included in new equipment or retrofitted. Using algorithms to monitor the motors and provide them with the optimal amount of power required to perform a given mechanical task, the motor efficiency system reduces energy use without changing the speed of the motor. E-Save Technology has been installed on escalators at the U.S. Capitol Visitor Center.
