The 1969 Yenko bears the legendary 427 big block that pushes 430 horse‚ 450lb-ft of torque‚ and the ZL-1‚ which sports the first 427 aluminum block made by Chevy. This monster of an engine pushed out close to 500 horse‚ and 475lb-ft of torque. In the early 80’s both car companies went through some dramatic changes. For instance‚ the thunderous V8’s were replaced with six cylinder engines‚ and Mustang even had

Operating principle * Whenever a piece of ferromagnetic material is located in a magnetic field a force is exerted upon the material tending to bring it into the position of densest

ABSTRACT Thrust & Torque Calculations for MOV’s using Microsoft Office Products Prepared by Michael C. Richard Teledyne Brown Engineering Desktop computing using Microsoft Office products have changed the way that engineering calculations are performed. But‚ is the change for the better or the worse? Engineering Managers are faced with the task of “computerizing” engineering calculations all the time. This paper presents some guidance on how to choose the method that best suits your calculation needs

at synchronous speed. • Stator flux induces an emf into the rotor bars. • Rotor current flows in the rotor bars producing an opposing magnetic flux to the stator. • Rotor flux reacts with the stator flux which in turn causes motor rotation (torque). • Torque is maintained because the rotor runs at a slower speed than the RMF. This is referred to as the slip speed usually around 4%. In other words the stator is dragging the rotor along in a rotational force. The stator core is laminated to reduce

according to the different rotors: the squirrel-cage induction motors and the wound induction motors. The squirrel-cage induction motors are commonly used when the load requires little starting torque‚ such as lifts and fans‚ while the wound induction motors are necessary used when the load requires high starting torque. The induction motor used in this experiment is a there-phase squirrel-cage induction motor. 2.2 Power converter Since it is necessary to adjust the voltage magnitude according to

Pre-heating Fuel for Charge Homogeneity to Improve Combustion Abstract – The idea of the automobile engine that people have is of one that is bygone. The automobile engine today is the pinnacle of engineering expertise‚ implementing the best of technologies and undergoing the best of manufacturing processes to make the closest possible achievement to perfection‚ from design to combustion. The art of perfection though starts much before the process itself. In case of the automobile engine

intensity of the interaction. The force developed from a Fig. 1 - CONCEPT OF ELECTROMAGNETISM winding is dependent on the current passing through the winding and the magnetic field strength. If more current is passed through the winding‚ then more force (torque) is obtained. In effect‚ two magnetic fields interacting cause movement: the magnetic field from the rotor and the magnetic field from the stators attract each other. This becomes the basis of both AC and DC motor design. AC MOTORS Most of the

service life. Drive commences by the power source applying a torque to the shaft of the small drive pulley‚ causing it to rotate at a steady speed n1. The tension in the ’tight’ upper straight strand will then exceed while the tension in the ’slack’ lower strand will become less than. This tension difference applies a torque to the drive load pulley‚ equilibrating the load torque‚ while the pulley rotates at uniform speed n2‚ thus transmitting the power to the load
