318162000 | CONTROL BY PATTERNS OR OTHER PREDETERMINED SCHEDULE MEANS | 9 |
20100134053 | CONTROL DEVICE FOR ELECTRIC ROTATING MACHINE AND METHOD OF CONTROLLING THE MACHINE - A control device has a unit for preparing a pattern having first and second periods by comparing a triangular wave and a sine wave having an amplitude ratio set at each value of a modulation factor, and selecting one pattern corresponding to an instructed modulation factor, and a unit for applying a controlled voltage, set at low and high levels in response to first and second periods of the selected pattern, to a generator. The triangular wave has a cycle duration obtained by dividing the cycle duration of the generator by product of 3 and odd number, a crest having a level higher than the sine wave at a timing of each first period, and a trough having a level lower than the sine wave at a timing of each second period. | 06-03-2010 |
20100225256 | Simple Pitch Control System for Objects of Right Circular Cylinder Body Geometry - A technique for controlling the pitch of a supercavitating projectile is disclosed. For example, the illustrative embodiment controls the pitch of a supercavitating projectile by shifting its center of gravity. The center of gravity of the projectile is shifted by moving a ferromagnetic mass inside the projectile forward or backward, depending on the desired pitch. In some embodiments of the present invention, the position of the ferromagnetic mass is directed by a controller that has a predetermined trajectory stored in its memory. | 09-09-2010 |

20130106322 | DIAL SWITCH FOR MOTOR CONTROL | 05-02-2013 |
20150035460 | ELECTRIC MOTOR DRIVEN PUSHERS FOR AUTOMATED CLIPPING PACKAGING APPARATUS - Methods, devices and computer program products automatically package an object, such as, for example, whole muscle meat pieces, in a covering material, such as, for example, netting. The devices include a pusher assembly, an electric motor, preferably a servo motor with a gear box, that drives a linear drive assembly. The devices can include a programmably adjustable index and/or speed profile for the pusher assembly. | 02-05-2015 |
20150115849 | SYSTEM AND METHOD FOR PAUSING AND RESUMING AN OPERATION OF A MOTOR - A motor controller coupled to a motor is described. The motor controller includes a computing device configured to receive a first command designating a duration during which to operate the motor. The computing device is further configured to operate the motor during a first portion of the designated duration, receive a second command to pause the operation of the motor, in response to receiving the second command, pause the operation of the motor, receive a third command to resume the operation of the motor, and in response to receiving the third command, resume the operation of the motor for a second portion of the designated duration. | 04-30-2015 |
318163000 | Motor running-speed control | 3 |
20090128065 | FAN WITH SOFT START FUNCTION - A bathroom ventilator fan with the soft-start function includes an impeller and a motor. The motor is coupled to the impeller for driving the impeller to rotate. The motor has a control module for driving and controlling the rotation speed of the motor according to a soft-start signal. The soft-start signal includes a soft-start section and a target-driving section. The control module slowly increases the rotation speed of the motor from the soft-start section to reach the target-driving section. | 05-21-2009 |
318164000 | Cyclically varying or repeated speed schedules | 2 |
20100079092 | REAL TIME LOAD ADAPTATION OF A MOTOR - A method of varying speed and direction of motor operating intervals in a food processing device to achieve real time load adaptation comprising a motor ( | 04-01-2010 |
20110181212 | CONTROL METHOD FOR FREQUENCY CONVERTER - A motor drive and a method in connection with a motor drive including a frequency converter are provided. The motor of the drive is connected to a load, and the motor is controlled with the frequency controller. The method includes the steps of converting changes in electrical quantities of the motor caused by actions affecting the load into observations representing the changes, selecting control symbols on the basis of matching of the sequences of observations with a set of valid patterns, and controlling the converter based on the selected symbols. | 07-28-2011 |
