Title: A CONTROLLER FOR AN INDUCTIVE LOAD HAVING ONE OR MORE INDUCTIVE WINDINGS
Abstract:
A controller for an inductive load in the form of a DC electric motor which has an inductive winding. Controller includes a first input for drawing a DC load current in a first period from a first energy source in the form of a bank of batteries. The first input supplies a first DC charging current to batteries during a second period. A second input draws a second DC charging current during the second period from a second energy source in the form of a DC power source. A control module issues control signals. A first drive circuit and a second drive circuit, both operate in a first state and a second state during the first period and the second period respectively wherein, in the first state, drive circuits are connected with the first input and are responsive to the control signals for receiving load current and selectively energising windings to create torque in motor.
