| 20120111114 | Method and Apparatus for Determining an Operating Point of a Work Machine - Method and apparatus for determining an operating point of a work machine and/or asynchronous motor driving the same, the operating point being characterized by the power consumed by and/or output rate of the machine, in which one or more operating point-dependent measurement variables of the machine are detected by sensors, and the measured values are evaluated and/or stored during operation of the machine. The operating point is determined without using electric measurement variables of the motor by determining a frequency linearly proportional to the fundamental tone of the machine through signal analysis, especially frequency analysis of a measured mechanical variable selected from pressure, differential pressure, power, vibration, and solid-borne or air-borne sound. From this, the rotational speed of the driving machine is determined, and the operating point characterized by the power consumed by and/or output rate of the machine is determined utilizing the rotational speed/torque relationship of the motor. | 05-10-2012 |
