20140018961 | POOL SYSTEM WITH USER SELECTABLE COMMUNICATION PROTOCOLS AND METHOD OF OPERATING THE SAME - A pool system comprising a pump system, an external device, a user-controlled input, and a controller. The pump system including a motor and a fluid pump coupled to the motor. The controller including a processor and a memory, the memory storing instructions that, when executed by the processor, cause the controller to: receive an input signal from the user-controlled input; receive data from the external device; interpret the data from the external device according to one of a plurality of communication protocols defined by the input signal from the user-controlled input; control the operation of the motor based on the interpreted data; and reply back to the external device by using the selected protocol. | 01-16-2014 |
20150110642 | PUMP, ASSOCIATED ELECTRIC MACHINE AND ASSOCIATED METHOD - A pumping device for pumping a fluid is provided. The pumping device includes a pump and a power housing. At least a portion of the pump is positioned within the power housing. The pumping device also includes a first motor and a second motor. The first motor is operably connected to the pump and adapted to provide energy to the pump. At least a portion of the first motor is positioned within the power housing. The second motor is operably connected to the pump and adapted to provide energy to the pump. At least a portion of the second motor is positioned within the power housing. | 04-23-2015 |
20150145459 | METHODS AND SYSTEMS FOR CONTROLLING AN ELECTRIC MOTOR - A system and method of controlling an electric motor using a motor drive controller are provided. The motor drive controller includes a rectifier configured to convert an AC input voltage to a DC voltage, a DC bus electrically coupled to the rectifier, an inverter electrically coupled to the DC bus and configured to generate an AC voltage to drive the electric motor, and a control unit. The control unit includes a sign calculation module configured to determine a polarity of each phase of a reference current command and a compensation module configured to generate a voltage compensation command signal using one of the determined polarities of the reference current command and a measured current, and one of a measurement of DC bus voltage and a constant DC bus voltage value, the voltage compensation signal compensating the drive controller to neutralize a deadtime effect. | 05-28-2015 |
20150148970 | SYSTEM AND METHOD FOR ENABLING WIRELESS COMMUNICATION WITH A MOTOR CONTROLLER - A motor controller coupled to a motor is described. The motor controller includes a wireless communication device and a computing device coupled to the wireless communication device. The computing device is configured to communicatively couple with a client computing device using the wireless communication device, wirelessly receive at least one setting from the client computing device, and operate the motor pursuant to the at least one setting, to move liquid in an aquatic environment. | 05-28-2015 |
