We are using conservative figures, but EC motors are usually 70 percent more energy efficient than a single PSC motor. They also meet the U.S. Department of Energy's standards for energy efficiency. Those three advantages — versatility, programmability and efficiency — make EC motors an ideal...
ECM (electronically commutated motor) motors are one of the advancements the HVAC industry has made in furnaces within the last few years. One of the goals of HVAC research is to find ways to increase the energy efficiency of systems to benefit homeowners, businessowners, and the environment as...
An automatic torque correction method of an ECM motor used for replacing a PSC motor. The method comprises: Step 1) obtaining, through calculation, torque data corresponding to a high-gear rotation speed group and a low-gear rotation speed group, and storing the torque data in a micro-...
