What else can I help you with?
How do you make a 9 wire three phase motor into a three speed motor?
You don't.
When does a motor not need a neutral wire?
If the motor is operated from a three phase three wire distribution system the motor will not need a neutral wire.
How do you wire a three phase motor with two speed to a three phase power supply lead numbers not specified?
There are many types of winding on a two speed three phase motor. The number of wires from the motor should have been stated. This is a guess that the motor is a six lead. The diagram is for a six lead out two speed, one winding, single voltage constant horsepower motor.See sources and related link below
How do you wire a three phase 2 speed motor to run on fast speed only?
Look on the inside of the motor's junction box. This is where the wiring diagram is located and it will tell you what connections to make.
How do you wire a three phase motor with capacitor start?
I have never come across a three phase capacitor start motor. Any three phase motors I have worked on are induction start.
How can you determine if a electric motor is 1 phase or 3 phase if there is no name plate?
Check the motor's terminal box. If there are three service input cables - such as red, yellow and blue - plus an earth wire, then it is a three phase motor. If there are only two wires plus an earth wire, then it is single phase.
On a 220 volt electric motor which is the neutral wire L1 L2 or L3?
If the motor wire numbers are L1, L2 and L3, it is not a single phase motor. It is a three phase motor. Also for future reference, a 220 volt single phase motor does not use a neutral.
What are the main parts of three phase motor?
Wire, bearings, rotor and stator.
How many earth wires are required for single phase motor?
There is only one ground wire needed on any motor, single or three phase.
What is the voltage rating of a motor on a 3 phase 4 wire 277V lighting circuit?
If the motor is a three phase the most likely voltage the motor operates on will be 480 volts.
Can a bad circuit breaker on a 3 phase motor cause the motor to run backwards?
No. If the motor runs backwards, swap any two phases to reverse the rotation, like this: Old wiring: phase A - brown wire - motor lead T1 phase B - yellow wire - motor lead T2 phase C - orange wire - motor lead T3 New wiring: phase A - brown wire - motor lead T2 phase B - yellow wire - motor lead T1 phase C - orange wire - motor lead T3
How do you wire three phase into the mains?
In the UK, the term, 'mains', refers to the supply voltage provided by the distribution system. In most residential properties, the mains' supply is single phase (there are exceptions: some European countries have three-phase supplies), in which case you cannot 'wire' a three-phase load such as an induction motor into the mains.
