Jul 12, 2017 How to Rewind an Electric Motor. Electric motors are relatively simple mechanical devices, but rewinding the coils on a DC motor.
Bill, I would imagine expensive. I do a lot of motor work for the rewind people and rarely get any motor work below 10 HP unless it's special due to the cost of new versus old. I do get a lot of inbuilt motors and the cost of these must be quite higher as I know what I charge for mechanical repairs and they still have to rewind on top of this. Other side of the coin is that I also have to modify cheaper modern motors to fit instead of the inbuilt ones and the plus side is many can be a greater power for the size.
Greg, et al, the older motors did indeed use more wire than the ones made in the 1960s, but they were more efficient than the newer ones. About 1990, the local electric repair shop was trying to sell our sawmill on buying their new 'energy saver' 3 phase motors.

Ran it for a month and when they read the results as compared to what the older motor had done during the previous month, they took their toys home and never bothered us any more. The new energy saver motors just were retrograded back to more iron and copper wire, IE: it was done right in the olden times. Motors had been reduced in weight to sell cheaper, well make that at a higher profit, to the detriment of efficiency which caused a poor power factor.
