However, in an electronic-firearm, an electric current instead of conventional mechanical action is used to ignite the propellant which fires the projectile. [2] There are two approaches to electrically firing the cartridge. One method retains the primer, which functions analogously as a conventional primer.
When the machine or motor is used as a motor, this EMF opposes the armature current, and the armature converts electrical power to mechanical power in the form of torque, and transfers it via the shaft. When the machine is used as a generator, the armature EMF drives the armature current, and the shaft's movement is converted to electrical power.
A synchronized Vickers gun fitted to a test stand; an electric motor drives a structure that simulates the propeller. The C.C. gear was not the only hydraulic gear to be proposed; in 1917 Air Mechanic A.R. Betteridge of No.1 Squadron Australian Flying Corps built and tested a gear of his own design while serving with his unit in Palestine.
Machine guns, such as the M2 Browning and MG42, are of this second kind. A cam, lever or actuator absorbs part of the energy of the recoil to operate the gun mechanism. An externally actuated weapon uses an external power source, such as an electric motor or hand crank, to move its mechanism through the firing sequence.
A growler is an electrical device primarily used for testing a motor for shorted coils. A growler consists of a coil of wire wrapped around an iron core and connected to a source of alternating current. When placed on the armature or stator core of a motor the growler acts as the primary of a transformer and the armature coils act as the ...
Armature control is the most common control technique for DC motors. In order to implement this control, the stator flux must be kept constant. To achieve this, either the stator voltage is kept constant or the stator coils are replaced by a permanent magnet .
A permanent magnet motor is a type of electric motor that uses permanent magnets for the field excitation and a wound armature. The permanent magnets can either be stationary or rotating; interior or exterior to the armature for a radial flux machine or layered with the armature for an axial flux topology.
The Lynch motor is a unique axial gap permanent magnet brushed DC electric motor. [1] The motor has a pancake-like shape and was invented by Cedric Lynch in 1979, the relevant patent being filed on 18 December 1986. [2] The Lynch motor is built from ferrite blocks sandwiched between strips of metal, instead of conventional copper coil windings ...
