  • What Does a Capacitor Do? - Oriental Motor U.S.A. Corp.

    The motor most likely won't run with the load unless the shaft is rotated by an external force (this is much easier with an ungeared, round-shaft motor). This is because we need at least two phases to generate a rotating magnetic field in the stator. This where the capacitor comes in. What does a capacitor do?

  • Why is the starting current of an 3phase induction motor

    Sep 13, 2011 · The starting current of a motor is usually much higher than the normal current of that motor's full load condition. So for the protection purpose, in case of selecting fuse, the fuse has to be rated 2-3 times the full load of the motor so it does not blow on start. An induction motor will have a starting current of around 6 times FLC.

  • Why does our new 480-volt 3-phase motor not start up? It

    Jan 05, 2009 · My reasoning is that a motor has a LRC when starting, and this LRC is the highest current a motor will ever draw no matter how much its loaded. Its basically the max current the motor will draw with the rotor locked down. The motor draws this LRC everytime the motor starts and is commonly referred to as starting current.
