| 摘要 | An induction motor system comprising an induction motor, equipped with a heat recovery and water pumping apparatus and an apparatus for controlling the electrical efficiency and resulting heat generation of the induction motor. The motor is adapted to be coupled to an AC source for supplying an AC signal. The controlling apparatus includes a switching device, user controls and optional inputs. The switching device is connected in series with the motor and is operative in either a high impedance state wherein significant current flow through the motor is prevented or a low impedance state wherein current flow through the motor is substantially undisturbed. The user controls provide motor operational input signals. The optional inputs provide setpoint and sensed water temperature input signals. The controller means receives the motor operational setpoint and sensed water temperature input signals from the user controls and optional inputs, and switches the switching device between its low and high impedance states in a predetermined sequence for inducing a phase delay in the AC signal. | ||||||
