Power assist of the motor is transmitted to the shaft which provides power assist to the steering effort. EPS ECU It receives data from many sensors and determines specific data which to be given to DC motor. Steering wheel It is also called as hand wheel or driving wheel. And it is used to control the steering of the vehicle. And it is a part of the steering system.
On this mechanical system we need to represent the forces affecting the angular displacement of the link of the arm. The best thing to do it is to draw a free body diagram of the two moments of Inertia J_m is the moment of inertia of the motor and J_l is the moment of inertia of the link i.e. the arm. The elements of the diagrams are the following: T_m -the torque generated by the motor θ_m-the angular displacement of the
1.1 INTRODUCTION ABOUT DISC BRAKE Fig 1.1 DISC BRAKE A disc brake is a type of brake which uses calipers to squeeze pairs of pads against a disc to create friction that resists the rotation of a shaft, such that a vehicle axle, either to reduce its rotational speed or to hold it stationary. In this action kinetic energy is converted in heat energy due to friction and the brake is applied. Disc brakes are used for motor vehicles but the principals of a disc brake are applicable to almost any rotating shaft. • DESIGN LAYOUTS OF DISC BRAKE Components of the Disc Brake Unit Cars uses the hydraulically operated foot brakes on the rear wheel. A layout of the proposed braking system is shown in Figure 4.1.
The layout of Series Hybrid system is shown below: Figure 2. Series Hybrid System Here in this configuration the engine only supplies mechanical power to a generator. As the generator rotates it creates electrical energy which is used to recharge the batteries. The batteries then supplies electrical power to the wheels. Power Split Hybrid They have the benefits of a combination of series and parallel characteristics.
Speaker identification is the process of determining which registered speaker provides a given utterance. Each block of the speaker recognition system can be described as below; • Input Speech: Input speech is the signal given by the speaker to the above system. Normally the human speech is the pure analogue signal, thus in order to process the signal further the analogue signal has to be converted to the digital signals. This conversion can be done by using the techniques such as sampling and quantization which is known as digital signal processing. But for the above system, the input speech signal is already given in the digital form which can be done by recording the voices of the speaker.
But, its stator is made of concentrated windings. The distribution of the stator windings of a permanent magnet synchronous motor (PMSM) is sinusoidal. Eventually, with the advent of electronic drives, it became possible to place the magnets of the motor on the rotor, and the windings on the stationary stator. The switching of stator current into the right phase depending on the rotor
To start within the motor assembly connected the pulley mounted on a common shaft through V belt which enables as to select or change the speed of the machine. The mechanical output of the first unit moves the secondary unit of the machine which comprises of the assembly of pulleys, spur gears mounted on the common shaft through bushings these results to move the cam too & fro. The cam is connected to a cam bender at the top end & bushing at the lower end through bushing. The movement if the cam bender results in the bended ring-bars at the output of desired
Many modern electric drive vehicles including electric locomotives and HEVs have regenerative braking systems.EVs use their drive motors to convert kinetic energy into electromagnetic energy Motors and generators operate under the same principle and can be used interchangeably. The First Law of Thermodynamics dictates that the EV will slow down as this occurs. The generated electrical energy can be dissipated through a resistive network (Dynamic Braking) or stored (Regenerative Braking). Vehicle has forward momentum .The wheels are coupled to the rotors of electric traction motors in an EV .Instead of a current being applied to the motor to turn the rotors, the rotors are turned by the wheels of the EV. The rotors experience opposing torque as current is induced in the motor coils.This opposing
When the stator winding is connected to a 3 phase AC source, it establishes a rotating magnetic field rotating at the synchronous speed. It is based on the Faraday’s Law of electromagnetic induction which states that wherever a conductor is placed in a time varying magnetic field emf are induced which are called induced emf, if inductor circuit are closed, currents are also induced which is called induced current. As the rotor winding in an induction motor are either closed through an external resistance or directly shorted by end ring, and cut the stator rotating magnetic field, an emf is induced in the rotor copper bar and due to this emf, a current flow through the rotor
Current flows from the negative terminal of the battery, through the circuit, and to the positive terminal of the battery Current in a closed loop also creates its own magnetic field, which you can determine by the “Right Hand Rule.” Making a “thumbs up” sign with your right hand, the thumb points in the direction of the current, and the curve of the fingers show which way the magnetic field is oriented An electric motor uses the attracting and repelling properties of magnets to create motion. An electric motor contains two magnets; in this science project, you will use a permanent magnet (also called a fixed or static magnet) and a temporary magnet. The temporary magnet is also called an electromagnet. A permanent magnet is surrounded by a magnetic field (a north pole and a south pole) all the time (hence the term "permanent"), but the electromagnet creates a magnetic field (a north pole and a south pole) only when electric current is flowing through a wire (hence the
