Which size of copper cable in mm should use for 90kW 440V 3phase 50Hz motor and can you know how is calculate?
cable size for the 90kW motor is 3CX150sqmm aluminum cable
When does a motor draw current more than its rated current?
This is a good indication that the motor is being overloaded. If the motor load is belt driven, remove the belt and then check the motor amps. If it goes back to normal FLA then there is a problem with the driven load. If the motor amperage stays high check the motor bearings for the problem.
How does the 3-phase induction motor acts like 2-phase induction motor if a phase is disconnected from supply?
yes the motor will run but will draw more current and the torque will be not constant means not smooth due to unbalanced current
An electric motor produces 2 horsepower at an efficiency of 80 percent what current does it draw from a 220 volt line?
P = iv
Which 12 volt bulb will draw the most current when connected to a 12 volt battery?
The bulb with the lowest resistance. Current = Volts / Resistance
What is the load current of 90kw induction motor?
90/3=30ma
Which size of copper cable in mm should use for 90kW 440V 3phase 50Hz motor and can you know how is calculate?
cable size for the 90kW motor is 3CX150sqmm aluminum cable
What is the Difference maximum unit current draw and nominal unit current draw?
Maximum current is defined by the rated KW of the device, say Motor. The motor may not run at its maximum rated capacity all the time. Nominal current is drawn when motor runs at nominal load.
When does a motor draw current more than its rated current?
This is a good indication that the motor is being overloaded. If the motor load is belt driven, remove the belt and then check the motor amps. If it goes back to normal FLA then there is a problem with the driven load. If the motor amperage stays high check the motor bearings for the problem.
What is locked rotor?
Locked rotor current is the amount of current a motor would draw if you energize the motor and the rotor (the spinning shaft) doesn't spin.
Why is motor current draw lower at full speed?
Because full speed is unloaded. As you load the motor, speed decreases, and slip increases, with an accompanying increase in current.
What happens if dc is given to induction motor?
It will draw a heavy current and coils will be brunt.
What current will a 100w electric fan motor draw when you plug it into a 240v wall socket?
0.4166666
Why does a slow motor create high amps?
Excessive resistance (drag), will cause motor to draw more amps (current flow) to operate.
How does the 3-phase induction motor acts like 2-phase induction motor if a phase is disconnected from supply?
yes the motor will run but will draw more current and the torque will be not constant means not smooth due to unbalanced current
Does a 5 hp electric motor draw less amperage if it is not doing 5 hp of work?
All motors draw less current when their load reduces.
If defective blower motor draws more current than a good motor because?
defective motor will not run, also cause the blower motor speed resistor to burn out and eventually blow the fuse. a motor with defective bearings will draw excessive current causing either the fuse to blow or cause the motor to overheat
