Early versus late spindle motor?

Can anyone tell me the difference between the early short/fat spindle motor (as used in the all-green Triacs) and the later tall thin motor? Is the later one a big improvement?

early green triacs with the wide head have a small three phase motor 1/2 hp i think, the newer white triacs have a 1hp dc motor.
Current trend is to fit a 3 phase 3hp water cooled high frequency spindle (200 - 400hz, 18000 - 24000 rpm) and gear it down 3:1 to get a more powerful and faster spindle.
