| 20120139470 | Phase Detection Methods, Apparatus, And Systems For Transport Refrigeration System - Transport refrigeration systems such as container refrigeration systems can operate on 3-phase power supplied by an external power supply such as in storage when powered by a generator system. If the refrigeration system is equipped with 3-phase motors, it is necessary to provide a phase detection and adjustment capability to the refrigeration system if the rotational direction of these motors is relevant to the operation of the refrigeration system. Embodiments according to the application provide systems and method for phase detection in a refrigeration system. | 06-07-2012 |
| 20140327386 | RADIO-CONTROLLABLE AC-POWERED MOTORS WITH SEVERAL FUNCTIONS - This invention relates to radio-controllable AC electric motors, which receives their power from the AC (alternating current) power line. A less costly motor, which is readily controllable is achieved by substituting control-units previously manufactured and existing inside a motor, replacing them with an external RC control which contain similar control-unit's. The external RC controls is less costly than previous control's, making the overall cost of the motor package less costly, with the added bonus of being able to remotely control the motor with, many control function. | 11-06-2014 |
| 20160134210 | MODULAR MULTIPLE SINGLE-POLE ELECTROMAGNETIC SWITCHING SYSTEM AND METHOD - One embodiment describes a wye-delta starter, which includes a first single pole, single current carrying path switching device that selectively connects and disconnects a first winding of a motor in a wye configuration; a second single pole, single current carrying path switching device that selectively connects and disconnects the first winding in a delta configuration, in which the first switching device and the second switching device are coupled via a first interlock; a third single pole, single current carrying path switching device that selectively connects and disconnects a second winding and a third winding of the motor in the wye configuration; a fourth single pole, single current carrying path switching device that selectively connects and disconnects the second winding in the delta configuration, in which the third switching device and the fourth switching device are coupled via a second interlock; and a fifth single pole, single current carrying path switching device that selectively connects and disconnects the third winding in the delta configuration. | 05-12-2016 |

| 20150097511 | Ceiling Fan Motor With A Switch Device For Controlling Rotation Speed And Direction Of The Ceiling Fan Motor - A ceiling fan motor with a switch device for controlling rotation speed and direction includes a motor starting capacitor, a multi-stage switch and an AC power source. The motor has a main coil and a secondary coil. The motor starting capacitor is electrically connected between the main and secondary coils. The multi-stage switch includes a common contact, at least one rotation speed contact electrically connected to a second main contact of the main coil, a rotation direction contact electrically connected to a second secondary contact of the secondary coil, and a conductive member having a first conductive end electrically connected to the common contact and a second conducive end electrically connected to the rotation speed or direction contact. The motor starting capacitor cooperates with the multi-stage switch to control rotation speed and direction of the ceiling fan without requiring the use of a rotation direction switch or remoter controller. | 04-09-2015 |
