Patent number: 6819069Abstract: The rotation speed of an electric motor (9) is controlled by a controller (6) which receives its setpoint from a characteristic function (23). The characteristic function (23) calculates a setpoint for the controller (6) on the basis of an originally analog variable A (2) that is converted to digital by an A/D converter AD (10), with the aid of support values of a “MEM+DATA” characteristic that are stored in a memory (4); those values not predefined by the support values are calculated by interpolation.Type: GrantFiled: October 3, 2002Date of Patent: November 16, 2004Assignee: EBM-PAPST St. Georgen GmbH & Co.

Patent number: 6810292Abstract: The invention concerns a method for nonvolatile storage of at least one operating data value of an electric motor (32). The latter comprises a microprocessor or microcontroller (23) that controls its commutation, and it comprises a nonvolatile memory (74). In this method, when the motor (32) is switched on, an old operating data value is transferred from the nonvolatile memory (74) into a volatile memory (97) associated with the microprocessor (23) and saved there as a variable. The variable is updated by the microprocessor in the time intervals between the commutation operations (FIG. 13). At intervals of time, the operating data value saved in the nonvolatile memory (74) is replaced by the updated operating data value corresponding to the present value of the variable. A motor for carrying out this method is described.Type: GrantFiled: October 27, 2001Date of Patent: October 26, 2004Assignee: ebm-papst St. Georgen GmbH & Co.
