A method and a device are for operating a field-guided electric motor on a battery pack. In a motor mode, the motor current includes a field-forming motor current component and a torque-forming motor current component, which form a current amplitude of the motor current. In order to brake the electric motor fast with the option of possibly switching over to accelerating the electric motor at any time, provision is made for dividing the braking mode into two temporally separate braking sections. In a first braking section, the current amplitude of the motor current is kept constant by adjusting the field-forming motor current component. In a second braking section, the current amplitude of the motor current is variable. The switching of the braking mode over from the first braking section to the second braking section takes place when there is a fall below a predetermined speed of the electric motor.
