How to Make Simple DC Motor in Home

Simply a DC Motor is a device which convert electrical energy into mechanical energy. A DC motor is a mechanically commutative electric motor powered from direct current (DC). The stator is stationary in space by definition and therefore the current in the rotor is switched by the commutator to also be stationary in space. 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 (winding in which a voltage is induced) but non-rotating armature magnetic field and a static field winding (winding that produce the main magnetic flux) or permanent magnet. Different connections of the field and armature winding provide different inherent speed/torque regulation characteristics. Its operation is based on simple electromagnetism. A current-carrying conductor generates a magnetic field, when this is then placed in an external magnetic field,it will experience a force proportional to the current in the conductor, and to the strength of the external magnetic field. Now using the same principle lets see how to make a simple DC Motor using household Items.

MATERIALS REQUIRED

Insulated Copper Wire
Round Magnet
Battery
Safety Pins
Electrician Tape

PROCEDURE

Step 1: Use insulated copper wire to make coil as shown in figure. it must be made in such a way that two ends of wire can be used as two terminals.

Step 2: Use electrician tape to bind safety pins in both sides of battery.
Step 3: Now place coil as shown in figure. We must ensure that current is passing through the coil. For the working of motor current must pass through coil.

Step 4: Now place the magnet just below the coil and your motor will start working (watch video to see working).

Energy generating speed humps

In your view there may be many uses of Speed Humps like Safety, Speed limiting etc, What if i say speed humps can be also used for power generation? you heard me right using a simple setup we can effectively us speed humps for power generation, So why speed humps? After consuming non-renewable source of energy for years people are looking forward for renewable source of energy.Search of energy lead to power generation using sunlight, wind, tide etc. When talking about new source of energy people are asking for effective, renewable, maintenance less, nature friendly energy sources. When talking about energy generation using speed humps all above conditions are matching so this method can be effectively used to power street lights, traffic signals etc. BASIC FLOW CHART MATERIALS REQUIRED Rack Pinion Large Sprocket Chain Small Sprocket Flywheel Large Gear Small Gear Generator Ball Bearing RACK AND PINION GEARS: The rack and pinion used to convert between rotary and...

Six Leg Kinematic Moving Machine

Four bar linkage are the closed loop kinematic linkage , they perform a wide variety of motions with a few simple parts. This project discusses the design & fabrication of one such mechanism (Four Bar Mechanism). In this project Six Leg Kinematic movement works on Grashof’s principle which states that the sum of the length of the shortest and longest links must be less than or equal to the some of the other two links. However this condition is necessary but nor sufficient. Mechanism satisfying this condition will fall into crank-rocker mechanism, double crank mechanism and double rocker mechanism. A frame, connecting rod, crank & a lever constitute to obtain the required motion. In this project we tried to show mainly the application of simple four bar mechanism. PHOTOS & DRAWINGS APPLICATIONS It would be difficult to compete with the efficiency of a wheel on smooth hard surfaces but as condition increases rolling friction, this li...

Mechanical Spider using Klann Mechanism

The invention provides a walking device which stimulates a gait of a legged animal. The device includes a frame with spaced axial mounts, a leg, axially connected upper and lower rocker arms which limit reciprocating leg motion. The leg is driven by a connecting arm powered by a rotating crank. The position and configuration of the axial connecting sites establish a prescribed orbital path that the foot undertakes with each revolution of the crank. Both rocker arms and the crank are axially mounted to the frame. The leg has a hip joint axially connected to the upper rocker arm for limiting hip motion, a foot and a knee joint axially connected to the connecting arm. The connecting arm has three axial connecting sites, one for connecting to the knee, another to the crank, and a third connecting site defined as a centrally disposed elbow joint connecting site which connects onto the lower rocker arm and limits knee joint motion. Under power, crank rotation is transferred to the connectin...
