Abstract
An electric motor coil can be configured according to the specific needs of each case, in order to be able to alter the torque/speed ratio the motor offers at any given moment. To this end, each winding of the coil involved in the motor is divided into a specific number of wires of the same section and length, so that these wires are grouped and insulated from each other, defining a specific number of groups, which are linked to a switching device based on a plurality of input probes and output probes to which the wires are connected. These sensors slide over the surface of a rotating drum which includes several circuits with various connection configurations for the different wires from a series of input and output terminals over which the sensors are capable of sliding.
Claims8
A configurable coil electric motor, which is of the type whose windings are divided into a certain number of wires of the same cross-section and length that are grouped and insulated from each other, with the ends of said groups of wires connected to input pairs and output pairs, characterized in that the input and output pairs are connected to a switching device, involving a frame in which a motorized shaft is integrated, controlling the angular displacement of a rotating drum whose surface is divided into as many transverse sectors as there are connection configurations provided for the wires of the motor coils, with the particularity that each of the sectors of the rotating drum includes an independent electrical circuit, in which a series of input contact terminals and a series of output contact terminals are established, connected via an intermediate connection circuit, terminals on which a series of probes or brushes linked to the frame are capable of coming into contact, to which the input pairs and the output pairs, each intermediate connection circuit defining selective connection of the wires of each winding according to different series/parallel configurations and combinations thereof.
The configurable electric coil motor, according to any of the previous claims, where the input and output sensors and are obtained from plates of electrically conductive material, which are arranged tangentially to the drum and are linked to a transverse rocker shaft, acting as a rocker, so that its end opposite that in contact with the terminals of the drum circuits is linked to at least one spring linked at its other end to a transverse bar provided in the frame, which causes said rocker plate to tend at all times towards the position of contact against the terminals of the drum.
