GMD is the name of a series of bipolar chopper drives, suitable for driving two-phase stepping motors, with four, six or eight terminals.
GMD drives are realized in single EUROPA format cards (100 x 160 mm.) and are equipped with a 32 pole, DIN 41612 form D connector. They are therefore designed to be assembled inside a RACK, complete with motherboard, that could be possibly supplied as an option by R.T.A.
R.T.A. experience, together with a careful design for these specific purposes, has led to a very reliable component, easy to use, with a competitive cost and offering best performances.
The wide range of current and voltage values permits to optimize the use of GMD series drives, with every model of stepping motor, in a great variety of applications.
Particular care has been dedicated also to obtain top performance and low power losses for both the card and the motor, limiting the need for forced ventilation, while the standard input and output signals facilitate the interface with the most common control systems.
| Vdc | Inf. min. | Inf. max. | Dimensions | |
| (VOLT) | (AMP) | (AMP) | (mm.) | |
| GMD 02 | from 55 to 85 | 1.6 | 6 | 100 x 160 x 45 |
| GMD 03 | from 55 to 85 | 4 | 9 | 100 x 160 x 45 |
| GMD 04 | from 95 to 140 | 5 | 12 | 100 x 160 x 51 |
| GMD 06 | from 160 to 190 | 5 | 12 | 100 x 160 x 51 |
It is foreseen the possibility to "sandwich" mount various optional cards, meant to expand the drives' processing and interfacing. For more information about their characteristics please go to OPTIONAL CARDS page.
Euroracks 19", 12,5" o 10,5" con motherboard MM series and power supply PS series are availables on request for multy axis applications. For more information about their characteristics please go to RACK page.
