How much does a traction motor weigh?
Two of the traction motors removed from a truck Each motor weighs 6,000 pounds (2,722 kg) and can draw up to 1,170 amps of electrical current.
Which type of motor is used for traction?
4.6
| Motor | Application |
|---|---|
| DC series motor | Traction system, Cranes, air compressors |
| DC shunt motor | Lathe Machines, Centrifugal Pumps, Blowers, Conveyors, Weaving Machine, Spinning machines |
| DC compounded motor | Presses, Shears, Elevators, Rolling Mills |
| Stepper motor | 3D printing equipment, Small robotics, CNC milling machines |
Which motor is used in railway electric traction?
DC motors are used on trains is because of their high torque and good speed control. Compared to AC motors, DC motors can provide industry applications with a fine balance of strong starting torque and controllable speed for seamless yet precise performance.
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).
How much horsepower does a freight train engine have?
In today’s new, six-axle freight locomotives this typically ranges from 4,300 to 4,400 horsepower. This amount is what actually makes it to the traction motors underneath the locomotive, but the engine produces more power than that.
Why DC motor is used in traction?
DC series motor has develops high torque at low speeds, low torque at high speed, this is the basic requirement of traction unit. Commutating property of series motor is good so we get sparkles commutation. Torque is unaffected by variation in supply voltage. DC Series motor maintenance cost is less.
Are locomotives AC or DC?
Modern AC locomotives tend to have better traction and offer better adhesive to the tracks than earlier models. AC diesel-electric trains are most commonly used for carrying heavier loads. However, DC diesel-electric trains are still very popular as they are relatively cheaper to manufacture.
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 . 40 to .
What is the difference between AC and DC traction?
DC train consumes less energy compared to AC unit for operating same service conditions. The equipment in DC traction system is less costly, lighter and more efficient than AC traction system. It causes no electrical interference with nearby communication lines.
