No, that sensor in the CR240 (I assume, as there's something similar in the CR210 that I have) is to detect when the tape as stopped moving to cause the thing to auto-reverse. You wouldn't try to control the tape speed from the spool motion anyway, the speed of the spool rotation depends on how much tape is wound on it, tape speed is controlled by the capstan.

The CR210 motor is electronically controlled, the speed control is part of that.
