Why are the ac series motors preferred for electric traction?
ac motor is nothing but induction motor.So check out for characteristics of induction motors.
Series motors are capable of taking huge starting torque like those of trains (traction)
ya the motor used in electric train is 3phase induction motor and dc series motor because both motors provide high starting torque
dc series motors
dc series motors are used because of torque vs speed characteristics.
dc series motor is used for traction...
The Apollo Lunar Roving Vehicle had 4 electric motors, one for each wheel, made by Delco. They were DC series-wound motors capable of 0.25 horsepower each.
Sometimes, for example in a separately excited dc motor. But in a series-wound dc motor the torque is proportional to current-squared, which gives the motor a very high starting torque and this makes series motors very popular for traction.
· Variable speed motor which changes speed drastically from one load condition to another. It has a high starting torque. Applications: hoists, electric trains, conveyors, elevators, electric cars.
450 series is far superior of the 400 series motors. 1977 450sl series is far superior of the 400 series motors.

The first traction engine was introduced in the 1850s. The first successful traction engine was developed after a series of experiments by Thomas Aveling in 1859.
speed control of dc motor is more easy as compare to any ac motor..and power operation of dc motor(s/t) is simple
The classic heavy starting load is a tram starting off from stationary, and for this the series-would dc motor is the preferred motor.
DC Series motor
DC Motor :- SHUNT MOTOR, Series Motor, Compund Motor, ( mainly used in traction system only. as there performanace is very poor & DC supply is not available easily so there uses is less then AC motors,) AC Motor:- Induction Motor ( Slip ring Type, squrrile cage Induction motor) Syncronous Motor.
what are the advanced applications of dc series motor
DC series motor can provide large starting torque.
It is impracticable to connect an electric bulb and an electric heater in series because it will divide the voltage.
AC series motor uses the electric current to run the motor. Whereas DC motor uses the battery power to run it. Answer An a.c. series motor is termed a 'universal motor', because it will run on either a.c. or d.c. A.C. series motors are constructed in essentially the same way.
dc series motor
B series do not fit on D series motors
DC motors generally use commutators. Also some single phase AC motors use commutators. They are the type which which have their field windings connected in series with their armatures and they can typically be found in home vacuum cleaners, DIY-type ac electric drills, etc.
Toyota uses AC motors, Honda uses DC motors. It varies with design goals.
There are far too many types of electric motors to fully explain their operation on this site. Some of the different types of electric motors include the following categories: DC, single phase AC, three phase AC, AC/DC universal, synchronous, asynchronous, induction, reluctance, stepper, servo, synchro, series connection, parallel connection, permanent magnet, commutated with brushes, self-commutated, brushless, linear, etc. However regardless of the type they all operate internally by creating patterns of magnetic fields that repel… Read More
A series dc motor does not have a well defined maximum speed, which depends on the friction in the bearings. It is dangerous to run this type of motor without a load because it could be damaged by excessive speed. Series motors are normally attached to massive loads, like trams or trains, which limits the speed, and the very high starting torque is useful for traction because it removes the need for a gearbox.
AC Series motors
because current is same in series resister
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
American non-CA version was approximately 70 hp, but an amazind 90-92 foot pounds of torque. As long as it can get traction, it'll pull a boat uphill all day long... For the 1500 series. the 750's were scream motors. Totally different...
becoz of high starting torqe to move train
Detroit Diesel has made several different types of motors throughout the years. You need to specify which Detroit motor you had in mind.. is it the 60 Series, is it the MBE series, is it one of the older 71, 92, etc. Series two stroke motors?
A series is an electric circuit with a single path.A parallel circuit is an electric circuit with multiple paths.
A series motor is employed for traction application which has starting torque and permits intermittent operations by braking, which cannot be expected of a general purpose motor.
All AC motors except for a Series Motor.
They are wired in parallel, series and series - parallel.
only shunt dc motors have varaible speed control. compound dc motors do however NT as much, plus they are just a mixture of series and shunt dc motors.
Like of series motors it got high torque
The Suzuki TS series is a series of motorcycles manufactured by Suzuki Motors. The first model in the series was released in 1969, and had a two-stroke engine.
Series & parallel.

There are lots of ways of categorising electric motors. For example, you can start by categorising them as either d.c. or a.c. then, within these categories you can continue to categorise them as (for example) 'series', 'shunt', 'compound', etc. (d.c. machines), and as 'induction', 'synchronous', etc. (a.c. machines) which, in turn can be broken down even further (e.g. induction: 'three-phase', 'single-phase', etc.), and so on.
A dc series motor can work on dc and ac because dc motors are totally reversible.
dc series motor used in metro train.
The K series motors have timing chains.
Types of AC Motors Classification Based On Principle Of Operation: (a) Synchronous Motors. 1. Plain 2. Super (b) Asynchronous Motors. 1. Induction Motors: (a) Squirrel Cage (b) Slip-Ring (external resistance). 2. Commutator Motors: (a) Series (b) Compensated (c) Shunt (d) Repulsion (e) Repulsion-start induction (f) Repulsion induction
The DC series motor is a high torque motor. so that it can pull heavy loads such as traction, lifts etc., the control of speed of a DC series motor is very smooth and easy.
Chevrolet S-10/GMC S-15/Sonoma
the basic difference is ,in short shunt motor the series field winding wont carry any current under no load condition whereas in long shunt motors series winding will carry no load current.....
