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?

Many single phase ac motors have been developed for traction purposes but only compensated series type commutator motor is found to be best suited for traction. Single phase induction motors have been abandoned as they are not capable of developing high starting torque.

Which motor is used in high speed traction?

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.

What are the requirements for traction motor control?

General requirements of Traction motors / traction system

• High starting torque. A traction motor must have high starting torque.
• Simple speed control –
• Suitable speed Torque Characteristics –
• Parallel Running –
• Overload Capacity –
• Size of Motor –
• high Efficiency.
• Braking –

Why is it called a traction motor?

AC induction motors known as asynchronous traction motors. Before the mid-20th century, a single large motor was often used to drive multiple wheels through connecting rods. This was the same way that steam locomotives would turn their drive wheels. The rotating shaft of the motor was also the axle for the wheels.

How many tons can a freight train pull?

So a typical over the road long haul freight train can weigh anywhere from 3,000 tons to 18,000 tons or more depending on the number of cars in the train. Local trains with less cars might weigh anywhere from 1,500 tons to 6,000 tons or more.
