I am guessing that what you are talking about is a two speed motor. The motor should have 6 wires coming out of it. There are two complete sets of three phase windings for each speed. Look on the motor name plate for the wire numbers or sometimes on the inside of the motor junction box. A 2 speed 6 lead motor should have the following markings, 1U 1V 1W for slow 2U 2V 2W for fast. Also check for the two different amp draws for each winding. These types of motors should be run from a reversing type contactor assemble so that individual overloads can be used on each of the high speed windings and on the low speed windings.
What else can I help you with?
What happens to the speed of a three phase motor if frequency is increased?
If the frequency supplied to a three-phase motor is increased, the motor speed will also increase following the relationship known as the synchronous speed. This increase in frequency will lead to a corresponding increase in motor speed, assuming that the load on the motor remains constant.
What happens to the speed of light in motor oil?
As long as the light remains in the motor oil, nothing happens to its speed.
Single phase motor speed is determined by the?
frequency of the power supply it is connected to. The speed of a single phase motor is directly related to the frequency of the alternating current (AC) power supply. As the frequency of the power supply changes, the speed of the motor will also change.
How do you reduce the speed of a 15 kW 3 phase motor without using variable speed control?
If the load is connected to the motor via belts, you can change the speed the load is turning by changing the pulley sizes. To get the load to slow down, increase the size of the pulley on the load; to get it to speed up, increase the size of the pulley on the motor. To reduce the speed of the motor itself, you'll have to alter the line frequency, which you can't do without a variable frequency drive attached to the motor.
Why can a run capacitor with a single phase motor remain in circuit after the motor starts?
A run capacitor is used to improve the efficiency and power factor of a single-phase motor by providing a phase shift to the auxiliary winding. Once the motor is running, the capacitor helps maintain a steady motor speed and performance. It remains in the circuit to assist in the motor's operation.
What happens to the speed of a three phase motor if frequency is increased?
If the frequency supplied to a three-phase motor is increased, the motor speed will also increase following the relationship known as the synchronous speed. This increase in frequency will lead to a corresponding increase in motor speed, assuming that the load on the motor remains constant.
Will single-phase Induction motor run on one winding once it has been started?
A single-phase induction motor has a main winding and a starting winding. When the motor has run up to normal speed the starting winding can be switched out, but for small motors this is not usually worth the trouble.
Will a single-phase Induction motor run on one winding once it has been started?
A single-phase induction motor has a main winding and a starting winding. When the motor has run up to normal speed the starting winding can be switched out, but for small motors this is not usually worth the trouble.
What happens to a 3-phase motor with a part-winding start when one side is disconnected while running?
the motor will continue to operate at a reduced speed and experience vibrations
Will a induction motor run on one winding once it has been started?
A single-phase induction motor has a main winding and a starting winding. When the motor has run up to normal speed the starting winding can be switched out, but for small motors this is not usually worth the trouble.
What happens to the speed of light in motor oil?

How do you make a 9 wire three phase motor into a three speed motor?
You don't.
Can 3 phase induction motor work when one phase is failed?
yes the motor will rotate but less then the rated speed and more heat will be desipated

Speed control of motor using SCR?
An SCR chip is commonly used to control the speed of a motor. The speed is controlled using an AC circuit and phase angles.
How do you wire a three phase motor with two speed?

no
