What is DC traction motor?
DC traction motors are direct current electric motors that provides the rotational torque of a machine, usually for conversion into linear motion (traction).

Why DC motors are used in trains?
DC motors are used on trains is because of their high torque and good speed control. Trains are a large-scale application; therefore, a DC motor can effectively and safely move the heavy load forward.
What is the speed of DC motor?
DC controls adjust speed by varying the voltage sent to the motor (this differs from AC motor controls which adjust the line frequency to the motor). Typical no load or synchronous speeds for an AC fractional horsepower motor are 1800 or 3600 rpm, and 1000-5000 rpm for DC fractional hp motors.
What is the difference between AC and DC traction motors?
The primary advantages of AC traction are adhesion levels up to 100% greater than DC and much higher reliability and reduced maintenance requirements of AC traction motors. The friction coefficient between wheel and rail is usually in the range of . 45 for old DC units to about . 90 for modern AC units.
Are traction motors AC or DC?
Traditionally, these were series-wound brushed DC motors, usually running on approximately 600 volts. The availability of high-powered semiconductors (thyristors and the IGBT) has now made practical the use of much simpler, higher-reliability AC induction motors known as asynchronous traction motors.
