20140210390 | ANGLE DETECTING MODULE AND METHOD FOR MOTOR ROTOR - An angle detecting module for a motor rotor is provided. The angle detecting module includes a permanent-magnet synchronous motor, three linear hail components and a processing device. The permanent-magnet synchronous motor includes a stator and a rotor. The three linear hall components are disposed on the stator; and the linear hall components are spaced by electrical 120 degrees. Each of the linear hall components outputs an analog signal after measuring a magnetic field, position of the rotor, and each of the analog signals has magnetically saturated third harmonic component. The processing device is electrically connected to the linear hall components, and the processing device optimizes each of the analog signals and generates an average rotor angle. | 07-31-2014 |
20120007367 | Fitness Equipment Energy Regenerating and Saving System - A fitness equipment energy regenerating and saving system is provided. The system includes a bidirectional power converter, a bidirectional power drive, a generator, and an energy managing circuit. The energy managing circuit activates the bidirectional power converter so as to enable the bidirectional power drive to feedback the power generated by the generator to an electrical grid when the generator is operated in a generator mode. The energy managing circuit sets the bidirectional power converter to a current-regulating mode so as to enable the bidirectional power drive to obtain the power required for driving from the electrical grid when the generator is operated in a motor mode. | 01-12-2012 |
