Electric working machine, and method of detecting overload operation thereof
An electric working machine according to one aspect of the present disclosure comprises a motor, a speed setting unit, a load detection unit, a determination unit, and a parameter setting unit. The determination unit calculates an estimated value of a heat generation amount of the motor, and determines that the motor is in an overload operation state when the estimated value reaches a predetermined threshold. The parameter setting unit sets a parameter to be used for calculating the estimated value and/or the threshold in accordance with a rotation speed set by the speed setting unit.
