  • Brushless Dc Motor Physics Report

    Brushes, coincidentally are used in brushed dc motors, as opposed to brushless dc motors, in which they are not used. there are two main types of motors, Brushed DC Motors, and Brushless DC motors. Brushes are the main reason why Brushed DC motors are in constant need of repairs as the brushes create a large amount of excess friction, thus meaning the brushes, commutators and armatures will be more susceptible to damage Key parts of a brushless DC Motor Armature Commutator Why use a Brushless DC Motor? A Brushless Dc Motor is far superior than its Brushed counterpart as, which you can guess by its name, It is Brushless. This is beneficial because as there is the less amount of parts, meaning that it is less prone to malfunction, meaning that it can operate for a longer amount of time without being maintained. This means it is more reliable, meaning that it is prefered when installing it in a high use machine. Brushed Vs Brushless Brushless Brushed Fewer Ways for Motor to Fail (No brushes, or an physical…

  • Brushless Dc Motor Effect Essay

    As there is no internal friction applied to the commutator it is able to spin at a higher velocity. Due no brushes more kinetic energy being able to be transferred to electrical potential energy and it wont be converted into, heat, sound and light energy. This will then reduce the amount of kinetic energy leaving the overall system that is created with the brushless DC motor. This will inturn provide a lot more output than a brushed motor. Another advantage due to this motor not having brushes…

    the mechanical energy that is fed into it by the turbine into electrical energy for use. This electrical energy is transported to the power grid through power lines and can be used by people everywhere (WVIC). Generators are used to convert mechanical energy into electrical energy. There are two types of generators which are alternating current (AC) and direct current (DC). The principal difference between them is that the electric current in direct currents runs in one direction whereas in…

  • Advantages Of Fuel Pump

    car that experiences this kind of problem may not pass an enhanced emissions test. Accelerated wear may also happen if debris or rust gets past the inlet filter sock. In some cases a pump will fail if contaminants enter and jam it, causing over heating for the motor and burning it out. In another case, a weak fuel pump or one that cannot generate adequate pressure can disturb the calibration of the fuel system. This can cause the engine to run in a weak manner or it may starve for fuel under…

  • Case Study: Direct Current (DC) Motors

    different types but they all operate with similar principles. In this paper, the construction, basic operation principles of a D.C motor as well as its applications will be discussed. 1.1 Construction of a D.C motor DC motors are made up of armature windings, stators and the rotors. The armature windings are embedded inside the set of coils /magnets (stator). When a voltage is applied to the coils, a torque is generated in the armature causing motion. 1.1.1 Stator and Rotor The stator is the…

  • Insulators In Physics

    Quantity Unit of measurement Electric current Ampere (A) Inductance Henry (H) Frequency Hertz Hz) Power Watt (W) Energy (work) Joules (J) Table 1.0: unit of measurements 3. AC (alternating current) is an electric current in which the direction of flow of the electrons reverses periodically by a sinusoidal law, hence having an average of zero, with positive and negative values. AC can be produced using a device called an alternator. This device is a special type of electrical…
