What motor must be never run without a load connected to them?
DC Series motor should never run without load connected to it because starting torque for DC series motor is infinite and running it on no load will damage the motor due to overspeeding.
Why starting currrent is higher in 3 phase id motor than 3 phase transformer?
CLARIFICATION AND ANSWER: 1. STARTING CURRENT PRODUCED ONLY BY ITS LOAD NOT SOURCE(SAY STEPDOWN TRAFO) 2. IF THE INDUCTION MOTOR IS THE ONLY LOAD OF THE STEP DOWN TRANSFORMER (SOURCE)-THE READING WILL BE AND SHOULD BE THE SAME IN THE SECONDARY SIDE UNLESS YOUR AMMETER IS IN THE PRIMARY SURELY WILL READ LOWER BUT POWER CONSUMPTION REMAINS THE SAME. 3. IT ALSO DEPENDS ON THE RATING OF THE MOTOR LOAD AND THE TYPE OF STARTING METHOD USED THAT YOU CAN MEASURE STARTING CURRENT.
How many amps does a 2 hp 210 volt single phase motor draw?
Then you are trying to get more HP out of the motor that it can supply. Back off on the load that the motor is driving or put a bigger motor onto the load.
How do you choose circuit breaker all the control circuit if i have 50kw power of motor?
The breaker should be sized to 250% of the motor's full load amperage.
What is efffect of load on motors?
As the load increases on a motor the amperage rises. Increasing the load amps over the motors full load amp rating can shorten the motor's life because of excessive heat. Motors should have overload protection in their circuits to prevent this condition from happening by tripping the motor contactor and opening the motor's voltage supply. <<>> Gets very warm .... vibrations., possible melt, seize, much energy expended.
Why wattmeter shows negative reading during no load condition of 3phase ac induction motor?
no load means the motor is acting like a coil
What is the difference between full load amps and running load amps?
Full load amps is the maximum rated amps that the motor should draw according to its nameplate rating. Running load amps is the actual amperage the motor is drawing at that point in time when the test is taken. Some motor loads vary depending on if the load is cyclic. The reading on this type of motor would be from no load amps to full load amps.
What motor must be never run without a load connected to them?
DC Series motor should never run without load connected to it because starting torque for DC series motor is infinite and running it on no load will damage the motor due to overspeeding.
When servicing a 2 hp motor your amp reading is 3.10 amps what voltage is the motor operating under?
It depends on whether the motor is run on load or whether it's running light.
What size breaker is needed for a 115v 60hZ 18.0FLA motor?
25 amps and it should be run through a contactor and motor over load set,you should set the over load to 5% above the motors full load current.And not your breaker should be a d curve type with 6ka rating.
How to connect a mechanical load to a motor?
To connect mechanical load to a motor, you couple it to the shaft of the motor.
What is a good or bad specific gravity reading on a load of aviation fuel What specific gravity reading should I be looking for on a new load out of a tanker?
depends on the type of aviation fuel, need more info
What should be the current of siemens 75 kw motor at no load?
starting current of 3 phase 75 KW induction motor
Is a motor considered to be a load?
Yes. A motor is considered to be a load of the power supply in use.
Can a 7.5 HP DC series motor pull a load of 1000 kilograms?
There is not enough information in the question to answer it. Any motor can pull any load through an appropriate pulley system. The question should include how fast that load needs to be moved.
What is the speed of DC series motor at no load?
No load speed is the speed that the motor run when it has no load, i.e., the motor is separated from the engine, that speed is than greater than the rated speed, because the rated speed is the speed whwn the motor are linked to the load and it is the full load.
What is the Full load motor current of a 75KW motor?
Full load starting current is typically in the region of 5or 6 times the full load motor current;.
