dc series motor :A series-wound DC motor has a low resistance field and armature circuit. Because of this, when voltage is applied to it, the current is high. (Ohms Law: current = voltage/resistance). The advantage of high current is that the magnetic fields inside the motor are strong, producing high torque (turning force), so it is ideal for starting a train. The disadvantage is that the current flowing into the motor has to be limited, otherwise the supply could be overloaded and/or the motor and its cabling could be damaged.
What else can I help you with?
Which types of screw threads are used in railway carriage couplings?
knuckle threads are used in railway carriage couplings.
What are hydraulic motors used for?
Hydraulic motors are commonly used in military vehicle wheel motors, crane drives, high powered lawn trimmers, and winches. William Armstrong was one of the first to construct a hydraulic motor.
Why I-sectional beam used in railway tracks?
I-sectional beams are used in railway tracks because the strength to weight ratio is excellent. They are also used because they have extra area which allows for stiffening of the metal without extra materials.?æ
For what purpose is a pneumatic valve used?
Pneumatic valves are used to close valves in high-speed internal combustion engines, pneumatic valves are mostly to help racing engines to get to high speeds.
How were steam engines used in the past?
Steam engines were first used in the tin mines of Cornwall, England to pump water from the mines which often extended out under the Cornish coastline.
Why does the electric engines are used for traction purpose rather than steam engines?
Steam isn't typically used for locomotives anymore. Normal operation of a locomotive is the generation of electricity with the use of an engine-generator set, often a diesel engine. This provides electricity for traction motors that turn the wheels of the locomotive. Excess electricity is stored in batteries, which provide power to the traction motors when the engine is not running, often to reduce noise and pollution in areas, such as cities, where it is undesirable to produce such noise and pollution.
Which type of motor is used for traction applications?
DC series motors...
Which motor is used in automatic railway gates?
BLDC motors
Type of traction motors used in Delhi metro?
In delhi metro used motor is INDUCTION MOTOR.
Does oil lubricate motors?
Yes, oil is used to lubricate internal combustion engines. Grease is used to lubricate electric motors. =========================================================== I have always used non detergent oil in my ELECTRIC MOTORS and grease for the bearings if there is a grease fitting
What things run on steam?
steam is used on things such as railway engines and standby generators.
How did the first automobile work?
Some used steam-powered engines, others used early petrol or gas engines. Some even used battery-powered electric motors.
What you Do With Oil And Gas?
Oil can be used in various motors or engines to power them along and gas can be used on a stove to start a fire.
Are GM General Motors engines two stroke engines?
GM did make 2 stroke diesel engines used in trucks and busses..they were noisy, requierd a super charger to run, loved to drink but very powerful.
Can jet planes go into space?
No, because there's no oxygen in space for the engines to use. The rocket motors used to go into space are supplied with combustion oxygen via the engines' plumbing.
Did GM goodwrench 350 motors come standard in 1979 Chevy pick up?
GM replacement engines are very similar to the engines used in those trucks, but not exactly the same.
What is a railway?
a railway is a track with engines it can be a mountain railway or just a railway * Added - A railway is a fixed guideway system (vehicles cannot leave the track) and can be powered by gravity, animals (including people), stationary engines, or locomotives (any vehicle that is self propelled). A train is a "consist" of multiple vehicles designed to move on the railway. As the term is used in conventional use today, a railway includes the track and all other wayside equipment, all the vehicles, stations, shops, and control centers.
