Ground ambulances are generally much less expensive, with an average emergency run coming in at $800 to $2,000, depending on the region and other factors, according to J.D. Fuiten, secretary of the American Ambulance Association. During an emergency, when the aircraft show up, there's usually no mention of money.
The traditional electric motor on a diesel-electric or electric locomotive is a DC motor. Internally, DC motors have two main components: the stator is the stationary outside part of a motor. The armature is the inner part which rotates.
1.) How They Work: Below: a simple diagram of the major parts of an original 1950s era direct current power diesel electric locomotive. Diesel Locomotives use electricity to drive forward motion despite the name 'diesel'. A large diesel engine turns a shaft that drives a generator which makes electricity. This electrical energy powers large electric motors at the wheels called 'traction motors'.
