摘要： A new assembly for a capacitor-run submersible motor-pump. The assembly has a built-in starting capacitor and a built-in switch associated with the starting capacitor. A running capacitor is located external to the assembly. With this arrangement, the assembly has only four terminals including a ground terminal connected to the frame of the motor. Thus, a four-conductor cable, i.e. the most commonly used cable, can be used to connect the assembly to an electric distribution panel. The switch is preferably of a centrifugal type triggered at a predetermined speed of the motor to cut the starting capacitor out of the circuit. The assembly is as compact as a conventional capacitor-start motor assembly.
