| 1.5 Examples of intelligent mechatronic modules
One of the first intelligent mechatronic modules is the SmartMotor module of the American company Animatics Sogr., which appeared on the market in 1994 [20]. It is based on a standard electric motor with a diameter 60 mm, in the rear part of the body of which additionally a photoimpulse sensor, an amplifier, a 32-bit programmable controller and a network communication device are installed. The module is universal, can be used in mechatronic systems for various purposes. The manufacturer emphasizes that 70% of the module consists of standard elements, which allowed reducing its cost and providing high relia- bility. The user can independently choose the control mode (by position, speed or acceleration), and also use computer control algorithms that compensate for the effect of backlash in the motion transducers on the dynamic characteristics of the module. Firm SIEMENS releases intelligent mechatronic modules SIMODRIVE POSMO A (Figure 1.10), consisting of the following elements: • valve motor with excitation from permanent magnets; • planetary (Figure 1.10, a) or worm (Figure 1.10, б) conversion movement (may be absent (Figure 1.10, в); • the braking device (may be absent); 166 • built-in photoimpulse sensor (BPhS); • power converter, which is structurally fixed on the engine cover; • a complete control device, including a regulator engine, positioning and programming blocks, as well as communication interface for connection in the PROFIBUS environment. Figure 1.10 – Intelligent mechatronic modules SIMODRIVE POSMO A distinctive feature of the construction is removable cover for connecting the power converter, which contains an integrated PROFIBUS bus address switch and a braking resistor, which makes it possible to disconnect the motor without disruption of communication and power connections in other devices. Thanks to the unification of communication and the simplification of the inter- nal structure of the module and its compactness is ensured. The module is controlled by a standard bus PROFIBUS, the following modes of motion are possible: • moving to the end position with a programmed speed; • movement with adjustable shaft speed and adjustable acceleration. Operator with special software can set temporary or logical conditions in the program of movement, use gap compensation methods, obtain messages about the current position and diagnostics of the module status. 167 The technical data of some SIMODRIVE POSMOA modules is shown in Table. 1.1 [3] Table 1.1 Technical characteristics of intelligent mechatronic modules SIMODRIVE POSMOA жүктеу/скачать 11,25 Mb.
