The resistance depends on how big the motor is. A small motor (less then 2-3 kW) , have greater resistance than a bigger one. Typically small motors have from 10 - 20 ohms to a few ohm. A 13 kWatt motor have typically 1-2 Ohm. A big 400 KWatt's motor have typically 10 milli ohms between the phases.
My spin drier has an induction motor of about ½ or ¾ HP on 240 v and its resistance is 7 ohms.
The resistance reading from any phase leg to ground should be infinity. Any reading over 5 meg ohms will be connectible.
This is the formula for horsepower. HP = I x E x 1.73 x %eff x pf./746. The efficiency of the motor will have to be guessed at along with the power factor. A motor has a lagging power factor so will use a value of .85. For the efficiency of the motor lets say 90%. The value of 746 is the amount of watts in one horsepower. Now applying the values we end up with a HP value. HP = 1.7 x 480 x 1.73 x 90 x .85/746 = 1080/746 = 1.45 horsepower.
The motor winding has gone to ground internally. The ability of the motor to shock you is caused by the ground wire missing or not connected. It is this ground wire that trips the breaker in short circuit conditions and disconnects the motor from the distribution system.
Combination of water and caustic soda for improving the resistance in starter, that's called Liquid Resistancestarter.If any slip ring Induction motor, at the time of startinggiven the external resistance required to rotor side, why because starting current and starting torque is very high.So we are using resistance starter depend on motor capacity , at that place using Liquid resistance starter.Liquid resistance starter (LRS) ,IN which externalresistance is liquid media which is use for the startingmethod of slip ring motor. For starting of slip ring motor external resistance arerequired so that we use liquid (addition of some causticsoda)as resistance so that is called as LRS.
If PSI is Pounds per Square Inch and HP is Horsepower then the only connection I know of is if you are trying to find the torque of the motor. Please rephrase the question.
A motor that draws 14 amps on 240 volts is probably a two horsepower motor, but it could be three depending on the efficiency.Watts = amps x volts. There are 746 watts in 1 horsepower.CommentIn North America, horsepower is always used to describe the output power of a motor. You can only find the input power by multiplying the supply voltage by the load current. You will, unfortunately, then need to know the efficiency of the machine to determine its output power in horsepower.
4.4 Horsepower
903 horsepower. 727 horsepower fom a gas motor and 176 from an elecric motor.
about 52 horsepower
6.5
8 Horsepower
A 5 horsepower motor would have 3,730 watts of power.
depends on the year and if your talkin about just to the crank or to the ground and what the motor is in if your talkin about to the ground. a 97 is putting about 295 to 305 to the ground in a single cab short bed with a 4l60e transmission.
The resistance of a motor winding is expressed in
25 horse power.
Brake horsepower is the hvac motor horsepower before the motor hp is dropped due to a load. Indicated, gross and SAE are other ways to rate horsepower.
225 horsepower
13.68 horsepower
