Overview Product Description E-Plus® motors are the industry’s first high efficiency, energy-saving motors, originally designed to meet the 1992 EPAct (Energy Policy Act of 1992) standards. With the expansion of the efficiency standards in EISA07 (Energy Independence and Security Act of 2007), E-Plus® motors now consist of motors previously exempt from the efficiency standards. In addition to their high efficiency, they carry the protection of the Speed Engineered® design and are warranted to offer the best performance available to inverter duty applications. E-Plus® 3 motors are designed to meet the higher efficiency requirements of EISA07, offering even heartier energy-efficient performance and savings. All E-Plus® 3 motors are Speed Engineered® rated for compatible inverter duty applications. Both E-Plus® and E-Plus® 3 motors are available in a variety of application configurations including: variable or constant torque loads, PWM, sensorless or sensored vector and with limited or broad speed ranges. Speed Engineered® motors are rated for 4:1 speed ratio at constant torque or 6:1 at variable torque.
