ShareEFFICIENCY CHARACTERISTICS OF SPEED-MODULATED DRIVES AT PREDICTED TORQUE CONDITIONS FOR AIR-TO-AIR HEAT PUMPS.
Author(s) : RICE C. K.
Summary
EXAMPLES OF SYSTEM (MOTOR PLUS INVERTER DRIVE) EFFICIENCIES OF TWO BROAD TYPES OF ADJUSTABLE SPEED CONTROL ARE COMPARED FOR PREDICTED COMPRESSOR AND INDOOR BLOWER LOAD PROFILES. THE 2 CLASSIFICATIONS ARE INVERTER-DRIVEN INDUCTION MOTORS AND PERMANENT-MAGNET ELECTRONICALLY COMMUTATED MOTORS. REFERENCE SINE-WAVE-DRIVEN INDUCTION MOTOR EFFICIENCIES ARE ALSO GIVEN.
