Definitions

  • the present invention relates to a device for controlling at least one electric servo motor with high power from a low voltage network.
  • This device is more specifically designed to ensure the electric motorization of a heavy turret on board a combat tank.
  • Low or medium voltage electrical solutions are also known.
  • the direct use of the low voltage network present on the tank implies a limitation of the installed power which does not ultimately allow the shooting on all terrain.
  • As for the medium voltage solution it requires a very powerful and therefore very bulky converter which it is generally not possible to integrate on a tank.
  • the available power is not in practice sufficient to allow the firing on the move.
  • the main object of the present invention therefore is to remedy these drawbacks and, to do this, it relates to a device of the aforementioned type which is essentially characterized in that it comprises, in combination: - a voltage step-up converter, a reversible switching amplifier supplied by the converter and supplying the current necessary for the motor to be controlled, which is of the type which can operate as a generator, and - a capacitive type electrical energy accumulator interposed between the converter and the amplifier.
  • the converter simultaneously supplies two amplifiers connected respectively to a motor for controlling the turret bearing axis and to a motor for controlling the site axis of the weapon carried by the turret .
  • the converter does not need to be very powerful and it is therefore not very bulky. There is therefore ultimately available, in a volume compatible with that available on a combat tank, sufficient permanent power to allow the shooting in progress in good operational conditions.
  • the converter is a mono-quadrant converter of the push-pull type, in order to avoid any restitution of energy at the source.
  • the voltage delivered by the converter is a medium voltage of the order of 270 volts.
  • the accumulator As for the accumulator, it consists of a battery of electrochemical capacitors connected in parallel.
  • the electric motor is advantageously of the collector and permanent magnet type with samarium-cobalt.
  • This device is located between a computer which gives the commands relating to each of the two axes, and the input axis of the reduction mechanisms respectively driving the turret whose inertia is of the order of 40,000 m2 kg, and the journaling of the weapon whose inertia is around 7,500 m2 kg.
  • It essentially consists of a step-up converter C followed by two reversible switching amplifiers A1 and A2 connected respectively to a motor M1 for controlling the turret bearing axis and to a motor M2 for controlling the axis of site of the weapon carried by the turret.
  • an electric energy accumulator B of the capacitive type is interposed between the converter C and the two amplifiers A1 and A2.
  • the converter C is supplied by the low voltage on-board network, for example 24 volts, and delivers at its output a medium voltage of the order of 270 volts, which obviously involves taking a certain number of safety measures for protection Staff. It draws on this network a power which is approximately ten times smaller than that which is finally brought into play in the device, ie for example 5 kW at peak, and can therefore be achieved in a compact form. It is planned single-sided, therefore irreversible, and push-pull type with all or nothing regulation.
  • Amplifiers A1 and A2 are based on the principle of current choppers operating in four quadrants.
  • the amplifier A1 corresponding to the axis of the turret is dimensioned at 40 kW at peak, while the amplifier A2 corresponding to the axis of the weapon is dimensioned at 12 kW at peak.
  • These electronic power amplifiers have bandwidths of 500 Hz and excellent linearity, as well as excellent efficiency above 95%.
  • the electronic switching amplifier in fact constitutes an adapter device without losses other than those necessary for the internal functioning of its own circuits, making it possible to constantly adapt the input power characterized by a constant voltage and a "free" current flow to the physical output quantities, that is to say the current linked to the motor torque and the voltage linked essentially to the speed of the shaft.
  • the electric motors M1 and M2, coupled by gearboxes suitable for the site and deposit axes, are designed to be able to operate as a generator.
  • they are of the collector and permanent magnet type with samarium-cobalt, so as to have a high volume torque and a rectangular torque-speed range of use.
  • the accumulator B which constitutes one of the essential elements of the control device according to the invention, it has a relatively high nominal capacity of the order of 1 Farad. It will for example be constituted by the parallel connection of 80 electrochemical capacitors of 12,500 ⁇ F each.
  • This accumulator makes it possible to recover, in the form of potential electrical energy, the kinetic energy available on the mechanical axes of the turret and the weapon, thanks to the reversibility of the control chains.
  • This aspect is essential if we consider that the losses of the device, for example in readjustment, represent 10% of the energy involved, the 90% remaining residing in a potential energy-kinetic energy exchange, and vice versa.
