To determine the current drawn by a 90 kW motor, you can use the formula: Current (I) = Power (P) / Voltage (V). For example, at a standard voltage of 400 V, the current would be approximately 225 amps (I = 90,000 W / 400 V). The actual current will vary based on the voltage supply and the motor's efficiency. Always ensure to consider the power factor if dealing with AC motors.
What else can I help you with?
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 no load current of a 90kw motor operating 440V 60Hz?
The no-load current of a motor, such as a 90 kW motor operating at 440V and 60Hz, can vary based on its design and efficiency. Typically, the no-load current for such motors ranges from 10% to 30% of the full-load current. To estimate the no-load current, you can use the formula: No-load current ≈ Full load current × (no-load current percentage). The full-load current can be calculated using the formula: Full Load Current (A) = Power (W) / (Voltage (V) × √3 × Power Factor).
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
What is the starter current draw?
Starter current draw refers to the amount of electrical current that an automotive starter motor consumes when it is activated to crank the engine. This current can vary widely, typically ranging from 100 to 300 amps for most vehicles, depending on the engine size and starter design. The high current draw is necessary to overcome the engine's inertia and initiate combustion. Prolonged or excessive current draw may indicate issues with the starter or battery.

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.
What current will a 100w electric fan motor draw when you plug it into a 240v wall socket?
To calculate the current drawn by the 100W electric fan motor when plugged into a 240V socket, you can use the formula: Current (A) = Power (W) / Voltage (V). Therefore, Current = 100W / 240V = 0.42 Amperes. So, the motor will draw approximately 0.42A of current.
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.
Why does a defective blower motor draw more current than a good blower motor?
A defective blower motor may draw more current than a good one due to increased resistance in the windings, which can occur from damage or wear. This higher resistance leads to inefficiency, causing the motor to work harder to produce the same airflow, thus consuming more electrical power. Additionally, issues like a seized bearing or obstructions can also cause the motor to draw excess current as it struggles to operate.
Why does a slow motor create high amps?
Excessive resistance (drag), will cause motor to draw more amps (current flow) to operate.
What you basically want is will each phase take 26 Amps current for 15HP 3 phase 415VAC motor?
Yes, for a 15HP 3-phase 415V AC motor, each phase will draw approximately 26 Amps of current when running under normal operating conditions. This results in a total current draw of 26 Amps per phase for the motor.
