A clutch lifespan measurement apparatus is provided to select an electronic clutch suitable for durability of an ATM(Automatic Teller Machine) by measuring lifespan of the electronic clutch. A clutch lifespan measurement apparatus includes an electronic clutch(130), a motor(110), a first RPM(Revolutions Per Minute) measurement unit, a torque limiter, and a controller. The motor provides an input gear(131) of the electronic clutch with a rotational force. The first RPM measurement unit measures RPM of a rotary shaft(151) when the electronic clutch is supplied with power. The rotary shaft is coupled to a friction plate of the electronic clutch. The torque limiter is connected to the rotary shaft and applies a regular load to the electronic clutch. The controller determines if the RPM measured by the first RPM measurement unit meets a predetermined RPM.
