The armature can be on either the rotor (rotating part) or the stator (stationary part), depending on the type of electric machine. Shapes of armature used in motors include double-T and triple-T armatures. [2] The armature windings interact with the magnetic field (magnetic flux) in the air-gap; the magnetic field is generated either by ...
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 ...
An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
Like most slot car motors, the Aurora pancakes ran on low voltage direct current. The term 'pancake' is also loosely used to refer to a car or chassis which has such a motor. Common Slot Car Motor Arrangements. Common Slot Car Motor Arrangements. The Pancake motor (far right) is seen end-on, with the shaft pointing toward the reader.
A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine.
Two of these motors were used in the French electric locomotive Midi E3301. A repulsion motor is a type of electric motor which runs on alternating current (AC). It was formerly used as a traction motor for electric trains (e.g. SR Class CP and SR Class SL electric multiple units) but has been superseded by other types of motors.
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.
This assumes that the electrical generator converts 90% of the engine's output into electrical energy and the traction motors convert 90% of this electrical energy back into mechanical energy. [citation needed] Calculation: 0.9 × 0.9 = 0.81 Individual traction motor ratings usually range up 1,600 kW (2,100 hp).
