Can you run a 400V- 50Hz multitivoltage -3 phase electric motor in Russia?
The usual supply in Russia is 220 v 50 Hz which corresponds to a 3-phase supply of 381 v. You need to check your motor to see what voltage range it is designed for, but 381 v is only 4.8% low so it should be all right.
What is the Phase to neutral voltage on a 400 volt 3 phase power supply?
The line-to-neutral (not 'phase-to-neutral'!) voltage on a 400V 3-Phase wye-connected system is 230V.Line voltage is the voltage as measured between any two (2) line conductors (hence its name!). Line voltage is often referred to as the 'line-to-line voltage'.Phase voltage is the voltage as measured between any single line and neutral. Phase voltage is often referred to as a 'line-to-neutral' voltage."400V" on a 400V 3-Phase wye-connected power supply indicates its line voltage. Line voltage in a wye system is always the phase voltage multiplied by the square-root of "3" (1.732) and reflects the vector sum of two individual phase voltages present in a three phase system.Thusly, if the line voltage is "400V", then the phase voltage is 400V divided by the square-root of "3" (1.732), which is 230V.Examples of this for North American power systems are 120/208V, 277/480V and 347/600V. Examples for other areas of the world are 220/380V, 230/400V and 240/415V.
What is Direct online Starters?
A direct on line starter, often abbreviated DOL starter, is a widely-used starting method of electric motors. The term is used in electrical engineering and associated with electric motors. There are many types of motor starters, the simplest of which is the DOL starter. A motor starter is an electrical/electronic circuit composed of electro-mechanical and electronic devices which are employed to start and stop an electric motor. Regardless of the motor type (AC or DC), the types of starters differ depending on the method of starting the motor. A DOL starter connects the motor terminals directly to the power supply. Hence, the motor is subjected to the full voltage of the power supply. Consequently, high starting current flows through the motor. This type of starting is suitable for small motors below 5 hp (3.75 kW). Reduced-voltage starters are employed with motors above 5 hp. Although DOL motor starters are available for motors less than 150 kW on 400 V and for motors less than 1 MW on 6.6 kV. Supply reliability and reserve power generation dictates the use of reduced voltage or not. A very well-known motor starter is the DOL Starter of a 3-Phase Squirrel-Cage Motor. This starter is sometimes used to start water pumps, compressors, fans and conveyor belts. With a 400V, 50 Hz, 3-phase supply, the power circuit connects the motor to 400V. Consequently, the starting current may reach 3-8 times the normal current. The control circuit is typically run at 24V with the aid of a 400V/24V transformer
What are the advantages of three phase induction motors over the other motors?
A Single phase induction motor includes a main winding, an auxiliary winding, a run capacitor, & a subsidiary star device. The auxiliary winding is configured such that the number of turns of the aauxiliary winding through which a current flows, varies according to the operating mode of motor. When the motor starts, the number of turns of the auxiliary winding through which a current flows is reduced there by increasing the start efficiency of the motor. when the motor runs in normal mode, the number of turns of auxiliary winding through which a current flows is increasing there by increasing the operations efficiency of motor
What is the difference in single phase and dual phase?
single phase means that there is only 1 live core in the cable (+) . so dual phase means there are 2 live cores in the cable. this is used to supply different parts of a device where needed. although three phase cable sometimes used to boost power to 400 vFurther answerActually it's not correct to say "boost power to 400 v". Power is measured in watts, not volts, although I agree the voltage of three-phase, at least in the UK, is 400v (I don't know about the US - they have lower domestic volatges than the UK anyway)CommentIf, by 'dual phase', you actually mean 'two phase', then this electrical system is quite rare, and consists of two phase voltages displaced by 90 degrees, as opposed to a three-phase system in which the phase voltages are displaced by 120 degrees.
What is the cable size for 1.5KW 3 phase induction motor?
Sir, what is the cable size for 1.5kw 3phase induction motor 400v?
What is the cable size for a 15kw 3 phase induction motor 90 meter runfor cable 400v?
If I consider power factor is 0.85 & motor efficiency is 95% then you have required 4 sq mm wire which is able allow passing 25.47 A current trough it.

400V
Can you run a 460v 60hz motor to a 400v supply?
yes can run but motor only delivers 90%rated power because v/f less by 10%

How can you operate a electric motor rated at 400V 3phase 50Hz on a 400V 3phase 60Hz system?
Yes, however, the RPM will increase by 20%, if the motor is connected to a shaft or driving something that can not handle the torque, then you might run to heating issues or performance issues.
