Induction Motor Rating Plate. All the high voltage motors are fi tted with drain holes Integrally cast feet allow a very rigid mounting and minimal vibration.
Understanding Induction Motor Nameplate Information from www.scribd.com
An induction motor can therefore be made without electrical connections to the rotor. The motors covered by this standard are assigned anyone ofthe ratings given 3.4 general purpose motors in 9.3. Grabner abstract—from the rating plate data of an induction motor the nominal efficiency can be determined.
If I Understand, The Ampere Rating Is Given On The Name Plate.
Motor insulation systems that are rated for inverter use will be specified on the motor nameplate (or a sticker). Terminal box is made of structural steel. All the high voltage motors are fi tted with drain holes
A 10 hp motor could run at 11.5hp. Rotate the shaft manually and make sure it rotates normally. From the rating plate data of an induction motor the nominal efficiency can be determined.
There Are Established Standard Indicators Of How Effective The Motor Does Its Job, As Well As Data On The Nameplate Concerning Safety And Reliability.
A motor with a 1.15 service factor can be expected to safely handle infrequent loads to 15% past it’s rated horsepower. The motors covered by this standard are assigned anyone ofthe ratings given 3.4 general purpose motors in 9.3. When i try to calculate ampere rating of induction motor.it is not calculated by the formula p=1.732*v*i*p.f.
The Power Rating (Hp Or Kw) And Frame Size, For Example, Are Specific To The Motor, Whereas Other Ratings May Have Tolerances Associated With Them.
Consistent induction motor parameters for the calculation of partial load efficiencies c. The rating plate data are usually rounded and subject to certain Types of motors split phase

Validity these instructions are valid for the following abb electric motor types when the motors are used in explosive atmospheres. You will operate the motor with auto transformer at no load increase the volt step by step and at each step record the motor speed until the speed go to be fixed at this moment this is your rated voltage. Without detailed knowledge of equivalent circuit parameters, partial load behavior cannot be computed.
