Abstract:
    A cordless electric mower having an energy management system that allows a user to operate the cutting blade motor of the mower at a wide range of user selected speeds, accordingly allows the cutting blade motor to be rotated at a maximum, predetermined speed and generates favorable cutting effect. Thereby, when the mower encounters heavy loading, the system limits the maximum amount of current from the motor by gradually reducing the rotating speed. This process greatly improves the operating efficiency of the mower and thereby significantly extends the available operating time of the mower on a single charge.
