What size of generator to run 5.5kw 400v 50Hz motor?
You need a 5.5kw generator to run a 5.5kw motor.
What current would be drawn by a 15KW 400V AC motor with a locked rotor?
yes
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?
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.
What cable size to use for a 1 kw motor for a 400v 50 hz 3 phase supply?
3 core 35 sq mm alu. Or 3 core 25 sq mm cup.
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%
Grease similar to kluber asonic GHY72 grease?
I HAVE A 15KW 50Hz 400V VEM MOTOR , I WANT TO RENEWAL THE GREASE
How do you calculate how much current a 5 kilowatt motor draws if it is a 3 phase motor 400v?
Power in a 3 phase circuit is given by W=√3*V*I*cosφ therefore transposing the formula gives: I=W/√3*V*cosφ where I=current in amps, W=power in watts, V=line voltage, cosφ=power factor (this should be on the motor plate, if not you could use 0.9) Regards ninenix
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
How can you operate a electric motor rated at 400V 3phase 50Hz on a 480V 3phase 60Hz system?
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.
What is the power dissipated by a resistance of 23ohm connected to a 400v peak to peak square wave source of 150hz?
Most resistors dissipate power as heat for current in any direction, so the frequency becomes irrelevant to this part of the question, but rather how long the circuit is on. The square wave tells me the power is always at 400V for all peaks, question becomes P = E * I = E2/R = watts.
