PROBLEM TO BE SOLVED: To suppress types of motors in all series by sharing the motors of respective fundamental series with different efficiency to constitute the respective fundamental series at a low cost.SOLUTION: Series of gear motors have: a plurality of types of gears G1 to G3 with different frame numbers; and a plurality of types of motors Ma to Me with different frame numbers, and constitutes a gear motor by connecting a gear (any of G1 to G3) with a specific frame number to any of the motors Ma to Me. The Series of gear motors includes: a fundamental series IE1 with low efficiency of motors Ma1 to Mc1; and a fundamental series IE2 with efficiency of motors Mb2 to Md2 higher than that of the fundamental series IE1, for example, the motor Mb1 to be connected to the gear G2 with a specific frame number 2 of the fundamental series IE1 is connected to the gear G1 with a frame number smaller than the specific frame number 2 of the fundamental series IE2, and used as the high efficiency motor Mb2 of the fundamental series IE2.SELECTED DRAWING: Figure 1 |
