The micromotors under study are of the variable-capacitance side-drive type with salient-pole and wobble (harmonic) designs. Polysilicon surface micromachining forms the basis of the

caliper‚ brake pads‚ a rotor‚ and a hub. The following is a basic description of a disc brake’s mechanism. 1. When the brake pedal is pressed‚ the brake fluid is forced to enter the caliper cylinder where the piston is sitting in. In turn‚ that fluid pushes the piston‚ which is attached with a brake pad on the other end‚ toward the rotor. 2. Once the brake pad is in contact with the rotor‚ the caliper contracts to bring the other brake pad to contact with the other side of the rotor as well. The pushing

parts of all steam turbines are similar‚ consisting of nozzles through which steam flows and expands (dropping in temperature and gaining kinetic energy) and the blades against which the swiftly moving steam exerts pressure. The blades are mounted on rotor drum‚ and an outer casing confines the steam to the turbine. Both temperature and pressure fall as the steam passes through the turbine. The greater the pressure drop‚ the more energy can be captured from the steam. The more efficient power plants

the differences between the two basic types of ac generators. 3. List the advantages and disadvantages of the two types of ac generators. 4. Describe exciter generators within alternators; discuss construction and purpose. 5. Compare the types of rotors used in ac generators‚ and the applications of each type to different prime movers. 6. Explain the factors that determine the maximum power output of an ac generator‚ and the effect of these factors in rating generators. 7. Explain the operation of

shaft‚ which causes it to accelerate or decelerate‚ depending on the direction of the unbalance. As the rotor changes speed‚ the relative rotor angle changes. Fig. 2 shows the relationship between the rotor (torque) angle δ‚ the stator magnetomotive force (MMF) F1‚ and the rotor MMF F2. The torque angle δ is the angle between the rotor MMF F2 and the resultant of the vector addition of the rotor and stator MMFs R‚ as shown in Fig. 2 Abstract— Due to increase of electric power demands‚ power systems

They are a fully articulated or semi-rigid under slung see saw type rotor system. Both have their own advantages and dis-advantages over the other. The fully articulated rotor system is complex by design‚ it has excellent control authority in the pitch and roll axis. It also typically has more than two rotor blades which reduces sound signature and

Changing brake pads and rotors can be done in only a few steps and by doing it yourself you can save yourself money. The first thing you have to do is lift the car up off the ground and take off the tire so you have access to the bake rotor. Now you are ready to take off the brake caliper. For this you have to take out the bolts or slide pins‚ depending on what type of brake calipers

induction motors An induction motor is a transformer with a rotating secondary winding. It has two essential components: an outer stationary stator and an inner rotating rotor. (Figure 1) [pic] Figure 1: Induction motor The three-phase induction motors could be categorized into two main types 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
