Torque can be increased by increase force and/or increasing distance from the fulcrum to where the force is applied. 2.1.5 Torque on a current-carrying coil in a magnetic field Torque on a current carrying conductor depends on: * Number of coils (n) * Strength of magnetic field (B)

drives have been employed in large grinding mills used in mining. The use of variable speed drives has allowed for the efficiency of the drive to be increased and also allows for a more flexible grinding process. The grinding mill drive’s speed and torque is varied depending on the characteristics of the ore they are grinding and on the quantity of ore within the mill. This allows for the grinding process to be flexible to changes in the process. The use of variable speed drives has also allowed

Upon the announcement of this change‚ the head of Hamilton ’s EE department conducted testing on motors from different manufactures and used starting torque as the deciding parameter‚ in order to define the specifications of a motor which could be used most economically. Is this just a "brush fire" or an important problem? *This is an important problem because Look at sales potential for DMC

Couplings A coupling is a mechanical device used to connect two rotating shafts for the purpose of transmitting torque from the driver to the driven piece of rotating equipment. There are two basic classes of industrial couplings: rigid and flexible. Rigid couplings are not designed to allow for any misalignment. Flexible couplings can compensate for some misalignment. Flexible couplings also allow for shaft end-float‚ or end-play‚ which is the inclination of shafts to move back and forth across

II. MECHANICAL STRUCTURE Both being internal combustion type diesel and gasoline engines can be considered as similar. Simply‚ both engines converts chemical energy into mechanical one by burning fuel. In combustion engines the combustion (explosion of fuel) occurs at combustion chamber with ‚ generally‚ help of oxidizer (air‚ another fluid‚ etc.). The output‚ high heat and pressure of the burning process is transfered to other components of the engines which expose pressure as a mechanical energy

sent to the motor. Since the shaft of the motor moves only the number of degrees that it was designed for when each pulse is delivered‚ you can control the pulses that are sent and control the positioning and speed. The rotor of the motor produces torque from the interaction between the magnetic field in the stator and rotor. The strength of the magnetic fields is proportional to the amount of current sent to the stator and the number of turns in the windings. The stepper motor uses the theory of

1 Balancing of Engine Parts Definition:Engine balance refers to those factors in the design‚ production‚ tuning‚ maintenance and the operation of an engine that benefit from being balanced. Explanation:Piston engine balancing is a complicated subject that covers many areas in the design‚ production‚ tuning and operation. The engine considered to be well balanced in a particular usage may produce unacceptable level of vibration in another usage for the difference in driven mass and mounting
