12/18/14 / #20140368138

Method of controlling a brushless permanent-magnet motor

A method of controlling a brushless permanent-magnet motor. The method includes dividing each half of an electrical cycle of the motor into a conduction period followed by a primary freewheel period. ... Dyson Technology Limited

12/18/14 / #20140368136

Reducing the power consumption of a brushless motor

A method of controlling a brushless motor. The method includes measuring a temperature of the motor, adjusting a control value in the event that the measured temperature is lower than a threshold, and exciting a winding of the motor. ... Dyson Technology Limited

12/18/14 / #20140366495

Cyclonic separating apparatus

A cyclonic separating apparatus comprising a first cyclonic separating unit and, downstream from the first cyclonic separating unit, a second cyclonic separating unit comprising a plurality of cyclones arranged fluidly in parallel about a first axis and a dust collector arranged to receive dust from each of the plurality of cyclones. Each of the plurality of cyclones in the second cyclonic separation unit comprise a fluid inlet and a fluid outlet, the plurality of cyclones being divided into at least a first set of cyclones and a second set of cyclones, the fluid inlets of the first set of cyclones arranged in a first group and the fluid inlets of the second set of cyclones arranged in a second group spaced along said axis from the first group. ...
