To reduce strain on the electrical system when starting the motor (needs that initial "kick" to get it going and would overload most systems).

It depends how it is connected ................
It could be to reduce electrical noise and interference.
It could be used to simulate a 3 phase connection as the capacitor can give a phase difference of 90 degrees to the other circuit.
As a snubber capacitor to prevent sparking on start up.
Depending on the size of the motor it could be a starting capacitor, used to store enough energy to give the current the initial push required to start the motor up.

the same reason that thay use them at all. some things take more power to start then to run. and its a pasive battery it kicks all the juse at ounce then its just another part of the line. maby i used to work for a place that made them. and that was the answer that i got. and ther are a lot of difrent sizes and typs. thay make some that turn on and of like a strob. ror cop cars.

well it could be for a lot of reasons the only way to know is to see the circut schematic, but i'm guessing it might be for speed control or for voltage regulation, i can't be sure

becoz they have to run contiuseoly,so it reqiured capacitor.
