Abstract
A highly efficient circulator system is provided, useful for hydronic systems, including both heating and cooling systems. The stand-alone circulator motor is controllable by input from certain sensors, preferably thermal sensors, which provide data enabling the controller of the brushless pump motor to vary its flow output to meet changes in systems loads. The circulator has a ceramic permanent magnet rotor, such as a ferrite, with an electronically, preferably sinusoidally, commutated, electro-magnetic stator controlling the input of electrical power.
