A process for providing replacement electrical motors to a number of disparate users that employ large, industrial electric motors for driving electrical generators or other rotary equipment. The process comprises providing a cooperative motor repair and replacement program and alliance for the repair and replacement of the electric motors; ascertaining the specifications and condition of the motors of each user who participates in the program, and transferring the motors of each user to one or more common climate-controlled storage locations, so that they will be in good condition and available when required. Desirably, the inventory of the user's own motors is supplemented by new motors in a sufficient quantity to satisfy the replacement motor requirements of all the users. To the extent required, an inventory is maintained of transition bases that are used to position a replacement motor so that it matches the specifications of the driven apparatus. The replacement motors and transition bases of the alliance serve to supply the needs of all of the members of the alliance, so that each member of the alliance does not have to maintain a complete inventory of replacement motors. Desirably, motor removal is accomplished at the same time that the replacement motor is transferred to the user's location, enhancing the speed of motor exchange, and minimizing inventory requirements.
