There is two motors, both motors having same hp, rpm, frequency but the rpm is different. For example one motor is 5hp, 3phase, 50hz, 1440 rpm. Second motor is 5hp,3phase,50hz,3000rpm. What is the current for both motors.
The calculation of current does not depend on the rpm you just need hp and voltage. A simple formula is 1 hp = 746 watts, and current = watts divided by voltage.

Why a dc series motor should never run at no load condition?
if you run the unloaded motor at max rpm the centrifugal forces will cause the motor to be totally destroyed so it is advisable to not to run it at max rpm it should be okay to run it till 50% of max rpm without loading it
What operating condition is most likely to overheat a motor?
When dc motor run full torque at low speed. Armature current is high and field current is set to max to get the torque. When motor is field weaken then temperature decrease at same cooling air flow

How do you convert hp to amp?
HP/.00134= Watts Then Watts divided by Volts = AMPS For expample. a .75 HP electric motor running on 220VAC uses 2.544 amps .75 / .00134 = 559.7015 Watts then 559.7015 / 220 = 2.544

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.

Make motor circuit how to calculate range of MCB?
To calculate the range of an MCB (Miniature Circuit Breaker) for a motor circuit, you need to consider the full load current of the motor in amps and select an MCB with a rating above this value to ensure it can handle the starting current and any potential overload conditions without tripping. It is recommended to select an MCB that is rated at least 1.5 times the full load current of the motor to provide a safety margin and prevent nuisance tripping.
