20130004148 | ELECTRIC MOTOR HAVING A PULSE WIDTH MODULATOR - The invention relates to an electric motor having a stator and a rotor. The electric motor also comprises a controller, wherein the controller is connected to the stator and/or rotor, and is designed for applying current to the stator and/or rotor for rotating the rotor. According to the invention, the controller comprises a pulse width modulator designed for controlling a power output of the electric motor, in order to generate a predetermined number of different current application patterns. The current application patterns each represent a power output of the electric motor, and preferably comprise a time sequence of current pulses, each having a current pulse duration. The controller is designed for applying current to the electric motor according to at least two different current application patterns for actuating the electric motor during a time interval of actuation, such that a power output of the electric motor in the time-based average of the time interval of actuation, in particular from the beginning to the end of the time interval, is different from the power outputs represented by the current application patterns in the time interval of actuation. | 01-03-2013 |

20130171009 | FAN SYSTEM AND METHOD FOR CONTROLLING A FAN MOTOR - In a fan system for an internal combustion engine of a motor vehicle, having an electrical fan motor with a commutator, and having a control unit which detects a fault in the fan motor and switches said motor to a voltage-free state if the motor current reaches a predetermined load-dependent switch-off value, the invention proposes that the control unit controls the fan motor with at least a virtually maximum power for a predetermined period of time if the motor current reaches a load-dependent switching value which is lower than the associated switch-off value by a predetermined amount. As a result, the fan motor is not switched off in an undesirable manner if only contamination, but not blocking, is present. | 07-04-2013 |
