A power tool having a motor is provided, wherein the motor includes a rotor and a stator, and wherein the stator includes a first winding and a second winding, wherein the windings are designed in such a way that the windings allow operation of the motor of the power tool at substantially full speed, but at substantially half the power compared with the comparison motor. In the comparison motor, the stator coils are substantially completely wrapped with a continuous wire layer. method for operating such a power tool and a method for carrying out charge equalization between two accumulators in a power tool is also provided. The double-wound stator can be used in conjunction with a bridge circuit made up of motor inverters and stator coils to allow charge equalization between two accumulators in a power tool.
A method for carrying out charge equalization between two accumulators in a power tool, the power tool having a first inverter for energizing first stator coils and a second inverter for energizing second stator coils, the first and second inverters forming a bridge circuit with the first and second stator coils, the method comprising carrying out via the bridge circuit charge equalization between the first and second accumulators,
