Abstract
One aspect of the present disclosure provides an oil pulse tool including an output shaft, an electric motor, an oil unit, and a controller. The oil unit is configured (i) to contain oil therein, (ii) to be rotated by an output of the electric motor, and (iii) to apply an impact to the output shaft using the oil. The controller is configured to perform a protection operation to reduce the output of the electric motor, in response to the impact having been applied to the output shaft such that an actual temperature of the oil unit can exceed a temperature threshold.
