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.
