Abstract: A base and movable platform are connected by a linearly extendable member, so that a motor may be adjustably located at a desired distance from other machinery which receives power. A motor mounted on such a movable platform may be linearly displaced so that belts, chain, or silent chain or the like may be adjusted to operate at a desired tension. In another embodiment, a motor driving a gear train may be adjusted so that the depth of engagement of meshed teeth and the allowable backlash between a driving gear on the motor and a driven gear may be adjusted and controlled. An automatic belt tension control system may be constructed by adding a tension sensor and a control module configured to maintain operating tensions within a preferred range and optionally to emit alarms or command a shutdown if an unsafe condition is detected.
