Abstract

PURPOSE: To enable smooth speed control of electric car at curved rail by setting the car speed by detecting a mean value of r.p.m. of both wheels of a truck.
CONSTITUTION: Speed power generators 14, 15 detect the r.p.m. of both sides wheels of a truck, the detected value being respectively converted into DC by reactifiers 16, 17 which are directly connected and added, while the added value coincides with the detected voltage at running on a straight rail. That is, the difference between the two voltages becomes a phase-shift control input value of the phase-shifter 22, 23 through amplifiers 20, 21, while the output of the circuit 22, 23 becomes the output pulse-width control input of the pulse-generators 24, 25, output thereof becomes the input value of the "ON" period of the thyristor controller 26, 27 and all of the above relations control the motor speed 2, 3. Through this system, a smooth speed control of the truck at running on a curved rail can be obtained.
