Abstract
A manual drive for a motor with an external rotational member coupled to a main shaft of the motor features a transmission rotational member which is movable axially along a shaft about which it rotates, such that the transmission rotational member of the manual drive is movable between a driving position at one location along the shaft where the transmission rotational member is rotatable so as to drive the motor and a braking position at a different location along the shaft where the transmission rotational member is in engagement with a braking member for braking the motor. The shaft features a threaded portion which is arranged to draw the transmission rotational member rotating in the first rotational direction along the shaft towards a first portion of the braking member by threadable engagement with the transmission rotational member for braking the transmission rotational member rotating in the first rotational direction.
