The six wire motor is probably a two speed or a dual voltage motor. Look on the underside of the motor's junction box. Here is where the wiring diagram of the motor is pasted. Look on the motor's name plate to see if it is a two speed motor. There will be two sets of amps and RPM and maybe voltages.
It could be that six terminals are brought out to terminal box so that it can be connected either in delta or star configuration. As stated above the name plate details would indicate the correct connection.

How do you make a 9 wire three phase motor into a three speed motor?
You don't.
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 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 3 phase power to 1 phase power diagram?
In an emergency and for a short period of time you can single phase a three phase motor but the motor will be loud, have terrible power characteristics and depending upon the use will burn up rather quickly. You should never try to run this in other than a life threatening emergency situation, the motors are not designed for it. Normally you don't. <<>> A three phase motor will not start on single phase. If the motor was started on three phase and loses a phase, it will stay running at a lower percentage of efficiency. Now a days the motor protection will not let a three phase motor run in a single phasing condition. All three phase legs of the motor are monitored and in a single phase condition the other two legs of the motor draw a higher current. This higher current is sensed by the motor's overload heaters in the motor's contactor and take the motor off line by opening the motor contactor. Now to the question, any two legs of a three phase system in electrical terms is known as single phase. As long as the three phase voltage matches the voltage needed in the single phase power diagram it can be connected to operate single phase equipment.
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 make a 9 wire three phase motor into a three speed motor?
You don't.
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 do you wire a three phase motor with two speed?
Star and delta connection
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.
How do you reverse a direction of a slip ring motor?
It is very simple. Just interchange any two phase wires. i.e. Y and B ( or ) R and B ( or ) R and Y for example Stop the supply. keep R phase wire as it is and disconnect B phase wire and Y phase wire. Connect B phase wire to the Y phase motor stud and Y phase wire to the B phase motor stud. Now give the supply, now motor revolves in opposite direction to the earlier.
