The schematic is a line diagram, not necessarily to scale, that describes interconnection of components in a system. The main features of a schematic drawing show: A two dimensional layout with divisions that show distribution of the system between building levels, or an isometric-style layout that shows distribution of systems across ...
The motor may be attached to the end of the actuator. The drive motor is of typical construction with a solid drive shaft that is geared to the drive nut or drive screw of the actuator. Compact linear actuators use specially designed motors that try to fit the motor and actuator into the smallest possible shape.
If the motor is generating electrical energy rather than using it, the motor drive could be called a generator drive but is often still referred to as a motor drive. A variable frequency drive (VFD) or variable speed drive (VSD) describes the electronic portion of the system that controls the speed of the motor.
Both one-way and two-way systems have been successfully used for decades. Interest in this application has grown substantially in recent history—not so much because there is an interest in automating a manual process, but because there is an interest in obtaining fresh data from all metered points in order to better control and operate the ...

The chairs would have been 90 cm high, the seat and the back support would have been 45 cm (18 inches) high. The diameter of the back is 8 cm or 3 inches. The width of the seat is 70 cm (27 in), the depth of the seat is 50 cm (20 in). The legs were 5 cm by 5 cm (2 in by 2 in) or 10 cm by 5 cm (4 in by 2 in).
