Abstract: A forward curved blower wheel has fan blades having relatively small leading edge blades angles and a relatively lengthy mean camber lines. The blower wheel also comprises leading edge notches adjacent its blower wheel inlet. The leading edge notches eliminate buffeting that would occur with such blades if such notches were not present.

Abstract: A controller configured to be coupled to an electric motor. The controller including a processor programmed to receive a signal indicating a stopping command of the electric motor, and control a current such that a capacitor coupled to the electric motor is not overcharged by regenerative energy when a stopping of the electric motor has commenced, wherein controlling the current includes one of the following: upon receiving the signal indicating the stopping command of the electric motor, ramping the current down below a threshold level, or upon receiving the signal indicating the stopping command of the electric motor, forcing the current to circulate in motor windings to prevent regeneration of energy in the capacitor.

Abstract: A bearing assembly cooperates with a bearing seat formed in a bearing housing and includes a bearing having an inner ring, an outer ring and a rolling element in engagement with the rings and an anti-rotation device. The anti-rotation device engages the outer ring to the bearing housing limiting rotation of the outer ring within the bearing seat. The anti-rotation device includes a first feature engaging the outer ring and a second feature engaging the bearing housing. The features limit the rotation of the outer ring within the bearing seat. The first feature has a resilient protrusion with a contact surface for engagement with the outer ring.

Abstract: A motor controller and methods of controlling a variable speed motor using the motor controller after a power-loss event are described. The motor controller is configured to be coupled to a motor. The motor controller includes a computing device configured to determine power is being supplied to the motor controller a power-loss event. The computing device is also configured to operate the motor in accordance with a predetermined operating schedule such that the computing device operates the motor at a first speed for a first time period, and after completion of the first time period, the computing device operates the motor at a second speed for a second time period.

Abstract: An air moving system including an electric motor, a load coupled to the electric motor, and a motor drive controller coupled to the electric motor is provided. A DC voltage generated from an AC input voltage provided to the electric motor tends towards zero at about twice a frequency of the AC input voltage. The motor drive controller includes an adjustment control module configured to receive a measurement of an instantaneous motor current value for the electric motor, determine a flux component value based on the instantaneous motor current value, and determine, based at least in part on the flux component value and a flux component demand value, an adjusted flux component demand value that causes the motor drive controller to adjust an operation such that an average flux component value based on the flux component value is substantially similar to the flux component demand value.
