I would like assistance with the electrical system of a streetcar/train, specifically in performing calculations related to speed, torque, and power for the motor and the train.Streetcar Gear SystemFrom my research, I have found that streetcars typically do not use traditional gear systems. Instead, the motor directly drives the truck (the assembly that holds the wheels and axles) to achieve the desired speed and torque required by the vehicle. The motor's speed and torque are controlled by a control box, which regulates the motor's performance according to the operational requirements.
Truck LimitationsThe truck that will be used has certain limitations, such as:
Maximun allowable speed: 50 mph
Maximum motor output: 75 hp
Motor specification:
The specification of the motor is the following:Output power 200 HPSpeed 1150/2000 RPMArm’s voltage 600 VArm’s current 317 AFields volts 220 VField Amps 8/3Field Winding CompoundTorque calculation of the…
