Abstract

An electric power unit for two-wheel vehicles comprising a batteries housing, from which current is supplied to a DC magnetic motor that is connected to a controller assembly, and a chain transmission driven by the DC magnetic motor, which is adapted to actuate a driven wheel of a two-wheel vehicle. The latter has a frame to which the electrical power unit for two-wheel vehicles is attached. The batteries housing incorporates a structure having two outwardly open compartments between which a hollow zone is interposed. Each of the two outwardly open compartments is divided in several partitions. Each of the several partitions is adaptable to receive one of several rechargeable batteries that are provided with terminals for contacting a wiring. Each of the two outwardly open compartments is provided with air channels air for heating the several rechargeable batteries. The DC magnetic motor with speed control comprises a stator including several alternating, equally spaced, permanent magnets that form a pair of parallel, concentric discs, a rotor including a central armature in a disc form, with two-loop windings and an even number of commuter segments. The commuter segments with odd ordinal numbers form first loop windings. The commuter segments with even ordinal numbers form second loop windings. Several brushes are disposed in a conventional holder that is concentrically affixed to the rotor. Half of the several brushes are used for starting the DC magnetic motor, while another half are used for regular functioning.

Claims

1. Electric power unit for two-wheel vehicles comprising

a batteries housing from which current is supplied to

a DC magnetic motor that is connected to

a controller assembly, and

a chain transmission driven by said DC magnetic motor being adapted to actuate a driven wheel of a two-wheel vehicle that has a frame to which said electrical power unit for two-wheel vehicles is attached,

said batteries housing comprising a structure having

means for forming two outwardly open compartments between which a hollow zone is interposed, each of said two outwardly open compartments being divided in several partitions, each of said several partitions being adaptable to receive one of several rechargeable batteries, said several rechargeable batteries having terminals for contacting a wiring;

each of said two outwardly open compartments being provided with

means for channeling air for heating said several rechargeable batteries, said means for channeling air for heating said several rechargeable batteries being located in said two outwardly open compartments, in and adjacent walls, as follows;

a) in a top and bottom walls and in a pair of second lateral walls, and open towards said several partitions, and b) adjacent a first lateral wall, for forming upper and lower passages;

said DC magnetic motor with speed control comprising, in combination,

a stator including several alternating, equally spaced, permanent magnets;

a rotor including a central armature in a disc form, with two-loop windings and an even number of commuter segments, said commuter segments having odd ordinal numbers forming first loop windings, while said commuter segments having even ordinal numbers forming second loop windings; and

several brushes, disposed in a conventional holder that is concentrically affixed to said rotor,

half of said several brushes being used for starting said DC magnetic motor, while another half being used for regular functioning; and

said controller assembly including

a Central Processing Unit; and

means for starting, stopping and regulating a speed of said DC magnetic motor, said Central Processing Unit being connected to several sensors adaptable to be positioned to different parts of a two-wheel vehicle in order to detect various conditions and performances of the latter.

2. Electric power unit, as defined in claim 1, wherein said means for starting, stopping and regulating a speed of said DC magnetic motor is a Pulse Width Modulator Motor Speed Controller.
