Because of this, steering knuckle need to have higher strength and stiffness but also must be lighter in weight and also size. In developing power output vehicle, the important goes to how to place the exact weight of linier and angular parts in steering knuckle. The overall performance of steering knuckle is affected by higher inertia force especially during driving which generated by the moving parts in the vehicle. This inertia comes from the uneven forces that act on the steering knuckle which can affect the lifetime and also the performance itself. Besides that, waste on material can also occur due to lack of knowledge and study in stress distribution on steering knuckle .
CHAPTER 3 Page | 9 3. INDUCTION GENERATOR An induction generator or asynchronous generator is a type of AC electrical generator that uses the principles of induction motors to produce power. Induction generators operate by mechanically turning their rotor in generator mode, giving negative slip. In most cases, a regular AC asynchronous motor is used as a generator, without any internal modifications. PRINCIPLE OF OPERATION: Induction generators and motors produce electrical power when their rotor is rotated faster than the synchronous frequency.
The Induction Motor Induction Motor applies alternating current and basically made up of two parts(8), a stator and a rotor. A stator remains stationary, while it rotates the rotor with the help of electromagnets. Induction motors are not just long-lasting, but also easy to maintain and inexpensive to run. In 1880s, Galileo Ferrari and Tesla were working on the same project of induction motor, but separately. None of them knew about each other’s findings and both of them submitted it in the year of 1888, though Ferrari submitted his research two months before Tesla’s submission.
The fuzzy logic will be applicable for Machine-Room-Less Elevators or traction Elevators. Some problems of elevators includes sudden stops, failure to open doors, abrupt landings, power failures and floor shifting. Our research includes some main problems and provided are the solutions for each problem which also mentions the existing scenario: Detection of Dirt for lubrication Problem: At the very top, there’s an electric motor with a wheel around which cable wires are wrapped. When the wear of cable wire occurs, small metal particles gets accumulated in the oil which leads to improper functioning of the elevator. Improper lubrication leads to contamination.
Introduction The occurrence of bearing currents in an induction motor has been known for decades. Asymmetric flux distribution is the basis that causes bearing currents inside the induction motor . It has been productively solved using modern motor design and manufacturing methods. Fig.1 shows two level PWM inverter fed induction motor with long motor cable. In many new and retrofit industrial applications the PWM inverters and motors must be at separate locations thus requiring long motor cable, which contributes over voltage at the motor terminal due to voltage reflection phenomenon.
They do not required clutch action and gear shifting manually by the driver. Thus there is no clutch pedal and no mechanical connection between the transmission and the selector lever. The transmission is controlled electronically through shift by wire. Steering system:
First of all place the car in front of the machine after the car position is set then inserted toes on the four wheel and adjust the angle of the wheel . It does not rectify properly but it reduces approximately. They used for if the car pulling in one direction means wheel is out of balance so wheel alignment is used for adjusting the angle of the
Static electricity currents will only produce an electric field. If electric current is moving will produce an electric field. The electric field can also be shaped due to changes in the magnetic field. The moving magnetic field can induce an alternating current and this electric current can also produce a magnetic field. The interaction between the electric field and the magnetic field will produce an electromagnetic field.
The input AC voltage is given to a current transformer and a voltage transformer. This part of the system is referred as comparator section. Voltage transformer step down the input voltage and current transformer is used to extract the waveforms of current. The output of the voltage transformer is proportional to the voltage across the load and output of current transformer is proportional to the current through the load. The output of both voltage transformer and current transformer is given to a comparator which acts like a zero crossing detector.
And often prefer these motors in systems with lighter loads, as the dominant form of motion is rotation. Linear motors Different types of linear actuators move in and out instead of spinning, often faster than changes in direction, especially when there is a need for very large forces such as is the case with industrial robots. Usually powered by compressed air (pneumatic engine) or oil (hydraulic motor). Series floppy drives Spring can be designed as part of the engine the engine, to allow better control of the force. It has been used in various robots, especially walking robots robot.
