An electric starter motor works by generating a heavy electric current at high speeds to turn and start an engine. The starter motor is equipped with a large electric switch that turns on and then off automatically in a short period of time. The electric switch is made to withstand high currents from a car battery and combines with a solenoid valve and electromagnet to start the engine.Continue Reading
The electromagnet is essential to complete the electric circuit, which then draws an iron rod to connect the car battery and the engine starter. This iron rod is fitted with a return spring so that the connection between the starter motor and the engine is not longer than it has to be. If an engine and a starter motor are connected for too long, the excessive spinning from the engine may damage the starter motor.
The electric starter motor is essential in starting up a modern engine, as it needs to be turned at high speeds. Once the engine has started turning, it can begin operation by filling the cylinders with air and fuel and then compressing it. In cars where the engine is mounted at the front, the starter motor can be found near the back of the engine, mounted low.Learn more about Engine
A car's engine works by creating internal combustion, using a mixture of oxygen and gasoline. Electrical energy is discharged into spark plugs by the distributor and ignition coil to ignite the fuel mixture, which creates an explosive force.Full Answer >
An electric PTO, or power take-off, clutch uses power produced by a power source, such as a battery or engine, to operate other components of a piece of machinery, such as a pulley, belt or attached piece of equipment. Commonly found in trucks, tractors and similar machinery, a PTO clutch transmits energy from the power-producing component of the vehicle to a secondary piece of equipment or an accessory.Full Answer >
An electric knife works by using a pair of serrated blades connected to a rotary motor and driver arm. The circular motion of the rotary motor is converted into a back-and-forth action that moves a driver arm attached to a pair of serrated blades.Full Answer >
A commutator reverses the direction of the current that travels from the rotor to the external circuit of an electrical generator or electric motor. Commutators have multiple metal brushes that make contact with the external circuit.Full Answer >
