What is the difference between a Techtop TAI 71A and 71B motor?

Both 71A and 71B belong to the Techtop TAI series. According to Techtop, the difference relates to the motor's internal design and performance requirements rather than its external mounting dimensions. Techtop advises that the same TAI 71 dimensional drawings can be used for the corresponding 71A and 71B motor variants. The 71B designation should not be confused with the separate Techtop TAIB brake motor series.
