Definitions

the present invention relates to an electric generator-motor system, particularly for use as a generator and a starter motor in a motor vehicle provided with an internal combustion engine.
the system according to the invention is characterised in that it comprises in combination - a rechargeable direct-current voltage supply, - a rotary electrical machine with a polyphase armature, - polyphase control means interposed between the electrical machine and the supply and adapted to act as rectifier means when the electrical machine is operating as a generator for supplying a rectified output current to the supply and/or a load, and as inverter means for providing the armature of the electrical machine with a polyphase current supply when the electrical machine is operating as a motor supplied with energy from the supply, and - voltage-reducing means for reducing the voltage between the control means and the supply to a value suitable for recharging the supply when the electrical machine is operating as a generator.
the rotary electrical machine is of the synchronous type and includes field-generator means with permanent-magnets.
the system may conveniently also include voltage-boosting means for increasing the voltage between the supply and the control means when the electrical machine is operating as a motor.
control means include a controlled polyphase bridge circuit piloted by an electronic control and operating unit.
the bridge circuit which is preferably of the three-phase type, and a respective controlled switching device, such as a transistor, is arranged in parallel with each diode.
an electric generator-motor system includes a rotary electrical machine, generally indicated 1, which is preferably of the synchronous type and has a three-phase armature whose windings are indicated X, Y and Z. These windings are connected in a star arrangement in the embodiment illustrated and are carried by a conventional stator, not shown.
the synchronous electrical machine 1 also includes a rotor 2 carrying field-generator means, preferably constituted by permanent magnets.
a three-phase bridge circuit is connected to the armature windings of the machine 1.
the circuit includes six rectifier diodes 4 each connected in parallel with the collector-emitter path of a respective transistor 5.
the bases of the transistors are connected in order to corresponding inputs of a piloting circuit 6 which forms part of an electronic control and operating unit, generally indicated 7.
Sensors 8 are also connected to the piloting circuit 6 and are associated in order with the windings X, Y and Z so as to provide electrical signals indicative of the currents flowing in these windings.
the sensors may be constituted, for example, by Hall-effect devices.
a speed sensor 9 is also connected to the piloting circuit 6 and provides electrical signals indicative of the angular velocity of the rotor of the electrical machine 1.
a capacitor 10 is connected in parallel with the bridge circuit 3.
a transistor, indicated 11 has its collector-emitter path arranged between the bridge circuit 3 and one terminal of an inductor 12 the other terminal of which is connected to the positive pole of a rechargeable direct-current voltage supply 13.
This supply is constituted, for example, by the normal battery of a motor vehicle.
a diode 14 is connected in parallel with the collector-emitter path of the transistor 11 and has its cathode connected to the bridge circuit 3 and its anode connected to the inductor 12.
the base of the transistor 11 is connected to an output of an operating circuit 15 included in the electronic control and operating unit 7.
a further transistor, indicated 16 has its collector-emitter path connected between the junction between the diode 14 and the inductor 12 and earth. The base of this transistor is also connected to an output of the operating circuit 15 of the electronic unit 7.
a diode 17 is connected in parallel with the collector-emitter path of the transistor 16, with its cathode on the side nearest the inductor 12.
a resistor indicated L in the drawing, represents a generic load connected to the supply 13.
a shunt resistor, indicated 18, is connected in series with the battery 13 and the load L. This resistor is also connected to an input of the operating circuit 15 and is intended to act as a sensor for sensing the current supplied to the battery 13 and the load L by the motor-generator system in operation.
capacitors 19 and 20 are interconnected in parallel between the positive pole of the supply 13 and a terminal of the resistor 18.
a sensor for providing the operating circuit 15 with a signal indicative of the voltage supplied to the battery 13 by the system (when it is operating as a generator) is indicated 21.
This sensor is constituted, for example, by a voltage divider or potentiometer in parallel with the battery.
the generator-motor system described above can conveniently be used as a generator and as a starter motor in a motor vehicle provided with an internal combustion engine.
the rotor 2 of the electrical machine 1 is connected mechanically to the flywheel 22 of the internal combustion engine by means of a differential reduction unit 21 which may be of the epicyclic type or the "harmonic drive" type.
the reduction unit 21 rotates the flywheel 22 at a considerbaly reduced speed in known manner.
the reduction unit transmits the drive from the flywheel 22 to the rotor of the electrical machine with a transmission ratio more or less equal to one.
the electronic control and operating unit 7 detects the rate of rotation of the rotor 2 of the electrical machine 1 in operation by means of a sensor 9 and, by comparing that rate with a pre-established reference, can establish whether the machine is operating as a motor or as a generator and consequently provides for the operation of the circuits 6 and 15 in the manner which will be described further below.
the rotor 2 of the electrical machine 1 When it is operating as a generator, the rotor 2 of the electrical machine 1 is rotated. The electrical machine therefore acts as a generator, in the manner of a normal alternator.
the piloting circuit 6 keeps the transistors 5 non-conductive.
the three-phase bridge circuit 3 therefore operates as a normal passive rectifier circuit and provides a rectified output voltage which is smoothed by means of the capacitor 10.
the operating circuit 15 keeps the transistor 16 non-conductive and pilots the base of the transistor 11 in an on/off manner with a waveform whose pulse width is modulated (PWM) in dependence on the value of the voltage in the load as detected by means of the divider 21.
PWM pulse width modulated
the capacitors 19 and 20 maintain the voltage in the load L, whilst the energy previously stored in the inductor 12 is recirculated through the diode 17.
the inductor 12 and the capacitors 19 and 20 together have an integrating and filtering effect on the voltage supplied to the supply 13 and the load L.
the voltage output by the bridge 3 varies according to the angular velocity imparted to the rotor 2 of the electrical machine.
the electrical machine When the electrical machine is driven at a speed faster than a certain value, it can supply (downstream of the recitifier) a direct-current voltage higher than the nominal voltage of the battery 13.
the circuit 15 reduces the voltage delivered to the battery in a similar way to the normal regulation circuits with which alternators used in motor vehicles are provided.
these regulation circuits regulate the voltage supplied by modifying the current flowing in the field winding normally provided in alternators for use in motor vehicles: these regulation circuits therefore force the alternator to operate in almost short-circuited conditions and the alternator can therefore supply only a fraction of its maximum power.
the voltage supplied by the machine to the battery is not regulated by modifying the field intensity but by choking the voltage supplied (by means of PWM).
the machine is thus free to operate at voltages higher than the nominal voltage of the battery and can therefore supply a higher average power than that which can be supplied by a motor-vehicle alternator/regulator unit of similar characteristics, with a consequent net improvement in energy efficiency.
the operating circuit 15 keeps the transistor 11 in the non-conductive condition and pilots the transistor 16 in an on/off manner by means of a pulsed signal whose pulse width is also modulated (PWM).
PWM pulse width is also modulated
the piloting circuit 6 pilots the three pairs of transistors 5 in an on/off manner in a cyclic sequence with phase differences of 120 o , so that the currents which are made to flow in the armature windings X, Y and Z of the electrical machine 1 have waveforms with phase differences of 120 o and hence simulate a three-phase current system.
the electrical machine 1 therefore acts as a motor and its rotor 2 starts to rotate.
the bridge circuit 3 operates as a simple rectifier bridge when the system is operating as a generator but operates as a three-phase inverter when the system has to operate as a motor.
the piloting circuit 6 may be of the type currently used for piloting so-called brushless motors.
the operating circuit 15 may be a normal integrated PWM modulator circuit easily obtainable commercially.
the operating circuit 15, the capacitor 10, the inductor 12 and the capacitors 19 - 20 form a voltage-boosting circuit when the system is called upon to operate as a motor and a voltage-reduction circuit when the system operates as a generator.
the two different operating modes are achieved simply by the different piloting of the transistors 11 and 16.
the anode of the diode 14 must be disconnected from the cathode of the diode 17 and connected to the battery 13 so that, when the system is operating as a motor, the current supplied to the electrical machine by the battery does not pass through the inductor 12.
