How many amps does a 30HP motor use hooked to 480v 3 pH 60Hz line?
The electrical code states that a 30 HP induction motor at 460 volts three phase will draw 40 amps. <<>> I = 33.34 AMPS IF EFF.= 95% AND P.F.= 85%
What are the Applications of induction motors?
Introductionl It is becoming very popular the utilization of squirrel cageinduction motors with variable frequency drives (VFD's) in theindustry.l The advance of power electronics technology and the cost of theVFD's are making this utilization possible.l The many advantages of this type of application are:ÙSpeed variation.ÙHeavy load inertia starting.ÙHigh starting torque requirements.ÙLow starting current requirements.ÙHigh efficiency at low speed.ÙHigh power factor.l The induction motor with VFD's replaces with advantage todaythe DC motors, and wound rotor motors.
How many Slip rings in synchronous motor?
If the synchronous motor is single phase then there are two slip rings & if this motor is three phase so the slip rings are three in number. Correction; I have never seen a single phase synchronous motor. It would cost more that it was worth. A synchronous motor has a separately excited field. If the excitation comes from a stationary DC source it has 2 slip (collector) rings. A brushless induction motor has no slip rings because the exciter armature rotates and so do the rectifiers. A permanent magnet motor, used with variable frequency drives, is another type of synchronous motor that has no slip rings. A three phase motor with 3 slip rings is a Wound Rotor motor. Wound rotor motors are variable speed motors that were used for such applications as bridges and cranes before variable speed drives.
Why induction motor coil spoil?
coil too many rewind
How many percent will be the starting current for motor?
Motor starting current is typically 5-7 times the rated current of the motor. (For three phase induction motors)
How many Methods can be use to control the speed of Single Phase Induction Motor?
How many methods can be used to control the speed of Single Phase Induction Motor? 1.injecting emf method 2.by frequency control method 3.induced voltage method
How many frequent start and stop operation possible for induction motor?
There is no fixed limit on the number of start and stop operations for an induction motor. However, frequent start and stop operations can lead to increased wear and tear on the motor, affecting its lifespan. It is advisable to minimize frequent start and stop operations to prolong the motor's longevity.
What would it cost to run a 3 phase induction motor?
Depends on the size. You can go from a few hp to many thousands of hp.

Why is my single phase induction motor drawing to many amps?
I have a single phase induction motor. It draws 8 amps on start up and climbs to 14-15 amps when I put a load on it. When I don't have a load it runs at 1 and climbs to 2-3 amps. It is normal operation for this motor to run at the lower number of amps with a load. But I don't know what is wrong.
Which motor is used in electric train and traction?
An electric train uses electric motors. Modern trains have many motors, they are mounted on the axles, one motor per axle. Some axles will be powered and have motors on them, some will not.
How many microfarad of starting capacitor is best for 15hp 3phase motor?
Starting capacitors are only required for single-phase induction motors. They are not necessary for three-phase motors.
How many pH value does pure water have?
*
For induction to occur What is necessary?
There are many reasons why it is necessary for induction to occur. One very important reason is transferring of heat.
