the next generation motors. In 1980‚the world’s first ultrasonic motor was invented which utilizes the piezoelectric effect in the ultrasonic frequency range to provide its motive force resulting in a motor with unusually good low speed‚ high torque and power to weight characteristics. Electromagnetism has always been the driving force behind electric motor technology. But these motors suffer from many drawbacks. The field of ultrasonic seems to be changing that driving force.

Procedure 1. H bridge theory was given by technician. 2. A circuit was set up as in figure 1. 3. H-bridge circuit was created. There were 4 switches and a motor in a circuit with two jumpers. 4. The theory was applied. The jumpers were connected to the alternate voltage supply. 5. The direction of DC motor was tested and determined. 6. All switches were in closed position at initial condition. 7. Only switch 1 and 4 was closed at the first condition as in figure 2(a). The direction of DC motor

SAMPLE PROBLEMS: 112- Topic 1: ELECTRIC FORCES & ELECTRIC FIELDS. 1) Charges of - 6 and + 4 nC are 3 m apart. Determine the force they exert on each other‚ and the electric field at a point midway between them. |Solution: This is an electrostatics problem (stationary charges). Since the charges|[pic] | |are of opposite sign‚ they will attract each other. The forces are indicated in the|

simple motor‚ or several coils‚ usually of several turns of insulated wire‚ wound onto the armature. The ends of the coils are connected to bars on the commutator. | The coils provide torque‚ as the current passing through the coils interacts with the magnetic field. As the coils are mounted firmly on the rotor‚ any torque acting on the coils is transferred to the rotor and thence to the axle. | Split-ring / commutator | The commutator is a broad ring of metal mounted on the axle at one end of the

electromechanical system. All car powertrains drive a driveshaft that turns the drive wheels of the car. Because an internal combustion engine delivers energy best only over a small range of torque and speed‚ the crankshaft of the engine is usually attached to a switchable gear train that matches the needed torque at the wheels to the torque that can be delivered by the engine. HSD replaces the gear box‚ alternator and starter motor with a pair of electrical motor-generators (MG)‚ a computerized shunt system to control
