a clear understanding of the apparatus which is an Internal Combustion (Spark Ignition Engine) and the purpose of retrieving measurements while carrying out the test. Moreover‚ to be aware of the connections between different parameters related to torque of the engine and speed kept at a constant all over. Introduction The Spark Ignition (SI) engines work on the principle of cycle of operations invented by Nicolaus A. Otto in the year 1876. (Khemani‚ 2008) Centuries ago internal combustion engines

Stepper Motor A stepper motor (or step motor) is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor’s position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller)‚ as long as the motor is carefully sized to the application. Switched reluctance motors are very large stepping motors with a reduced pole count‚ and generally are closed-loop commutated. Fundamentals of operation DC brush motors

complexity of the traditional methods for analyzing PGTs has kept many from becoming familiar with the capability of PGTs in mechanisms and machine design. In this paper a unified general formulation for simultaneously visualizing velocities‚ torques and power flow through a train is presented on a single nomograph. Therefore‚ the increasing complex mechanical systems‚ such as automotive transmissions‚ are much easier to understand. Nomographs of Fundemental Gear Entities (FGEs) are constructed

movement of the solar panel. However‚ conventional DC motor drivers used in solar tracking system do not provide any options for speed and torque control. Hence‚ the fixed speed of the DC motor leads to either too fast or too slow tracking movement. Usually‚ the output torque is set to the maximum. If the load (solar panels’ weight) is small‚ the maximum torque is not fully utilized and therefore energy is wasted. So‚ a fully adjustable DC motor driver for solar tracking system shows great potential

DV-II+ viscometer. The temperature of the oil sample was controlled by the circulation of water from a Brookfield TC-502 water bath temperature controller through a water jacket assembly around the oil chamber. This type of viscometer measures the torque required to rotate an immersed spindle in a fluid. Overall‚ the experiment yielded appropriate results: the viscosity of the oil sample decreased as temperature increased. However‚ upon research‚ none of the three SAE motor oil viscosity ratings

This is how the relative angle between the stator and rotor magnetic flux is maintained near 90 degrees‚ which generates the maximum torque. DC motors have a rotating armature winding but non-rotating armature magnetic field and a static field winding or permanent magnet. Different connections of the field and armature winding provide different inherent speed/torque regulation characteristics. The speed of a DC motor can be controlled by changing the voltage applied to the armature or by changing

synchronous electric motor which induces non-permanent magnetic poles on the ferromagnetic rotor. Torque is generated through the phenomenon of magnetic reluctance. 2. Define the characteristics of synchronous reluctance motor. The synchronous reluctance motor is not self starting without the squirrel cage. During run up it behaves as an induction motor but as it approaches synchronous speed‚ the reluctance torque takes over and the motor locks into synchronous speed. 3. Write the applications of syrm.
