How much capcacity of mm size four core cable well be used in running 1kw three faze motor?
Depends on the type of cable, the method of fixing the cable, the ambient temperature and the way the cable has been run to the motor (i.e in trunking, Conduit) Bascially a cable with a current carry capasity of 2 amps should be fine (1.45 amps with power factor of unity and no de-rating factors). Remember 1mm cable can carry at least 8 amps.
Also please improve your English when asking stupid questions!!
What else can I help you with?
Do you change the high leg if your three phase motor is running in reverse?
yes
Is three phase induction motor continue running when any of the two phase is disconnected?
This question doesn't really make any sense - any of the two phase? A three phase induction motor requires 3 phases to start - if a single phase is lost while the motor is already running then yes the motor will continue to run. A three phase motor will not start if it is missing a phase.
What is acceleration in a three phase motor?
It is a measure of how many rpm the motor gains in one second while running up after being switched on.
Why three phase motor run in reverse even if it is not wired to run in reverse direction?
If a three phase motor in running in reverse, then one of the phases is reversed, plain and simple. If the wiring is correct at the motor, perhaps the phase reversal occurred someplace else.
Why motor burn at single phasing?
A 3-phase motor will not run on single-phase power or if one of the three phases is disconnected. If the motor is not running, there is no back-EMF generated in the coils, and they draw excessive current, thus overheating.
What happend if one of the three phase of induction machine being disconnected?
the motor keep on running for a while but the current will rise on the two other
Can 120v and 277v be in the same conduit?
No you can not mix voltages. That being said if the lower voltage is part of the control circuit from a MCC control centre then yes they can be mixed as the low voltage control is part of the complete system.Composite power & control Teck 90 cable has the power feeders and usually 3/#12 or 3/#14 wires embedded in the same cable. These three wires allow for remote stop - start controls to be mounted neat the motor out in the field.

How many wires are used to wire a standard dryer?
In North America you would use a three wire cable. A dryer needs two voltage supplies. A 240 voltage for the heating element and 120 volts for the motor and controls. The three wire cable will have a ground wire in it also but in North America this is not counted as it is not a current carrying conductor. The size of the cable will be a 3C #10.
How do you replace window lift motor in 1994 ford explorer?
Makr dure the motor is axtually th eproblem. More often than not, the nylon gear breajs or the three nylon spacers thas engage it with the motor. If you hear the motor running, but the window does not move or moves only from some positions, then it is probably not the motor
