Abstract: A fan system includes a motor, a rotatable hub, and a plurality of fan blades. The motor is coupled with the hub by a hollow drive shaft, such that the drive system of the fan system is gearless. The motor is controlled by a PFC-based control module, which is in communication with sensors that are configured to sense parameters associated with operation of the fan system. The control module is configured to react in certain ways to certain conditions detected by the sensors, such that the fan system uses feedback-based control algorithms. A remote control panel is in communication with the control module. The remote control panel is operable to display fault conditions detected by the sensors. Blade retainers prevent fan blades from falling when a fan blade breaks free from the hub. Pins prevent the hub from falling when the hub breaks free from the rotor.

Abstract: A combined d.c. brushless motor and drive control assembly for a rotary mower includes a hollow motor housing, a cover removably attached to an open rear end of the housing, and an end shield mounted to an internal shelf of the housing adjacent its rear end. The end shield and a front wall of the housing define rotary bearing seats for a motor drive shaft. An electronic circuit board including motor drive electronics and feedback sensors is mounted to the housing or to the cover, and is positioned at an axial location between the internal shelf of the housing and the rear wall of the cover. The housing is configured for mounting on a shroud of the rotary mower such that at least the removable cover is above the shroud and easily accessible, whereby repair or replacement of the electronic circuit board is facilitated.
