Generally though, motor manufacturers make a limited number of physical sizes of motors called "frames", then have different windings inside of those frames to give you the different power ratings and/or speed ratings. In North America, the standardized frame dimensions are handled by an organization called NEMA (North American Electrical Manufacturer's Association) and everywhere else in the world, the standards are maintained by IEC (International Electrotechnical Consortium). So depending on where you are located, you would contact either of those organizations for details on what the standards include.

There are two standards by which frame size is given one is IEC and the other NEMA which is more prevalent in US.We mostly follow IEC.
Now specific to your question
160 is the shaft centre height from the base subscripts are added to this S or M Or L which means short core ,medium and long core lengths.For example 160M will have a rating of 11KW on 4 Pole.Now 15Kw 4 p is also in 160 frame with alonger core length and desinated as 160LThe dimensions particularly mounting ,shaft dia is fixed 92Pole is slightly smaller).This is done so that any make can be replaced with any other make.NEMA dimensions are different from IEC.Manufacturers add series refLike series A160L etc.My guess is EBK means its a electrical brake motor.

Pl. refer to any motor manufacturers web site and look at motor details.You will have dimension drawing and other details.ABB, Siemens, are some of the manufacturers whose web site will give u all details and u can refer to lincon or any us manufacturers motor catalogue.Google wiki will explain everything
