Indramat MDD

Indramat MDD Motors

Bosch Rexroth's MDD series of digital AC servo motors offers a lineup of nine different models, each tailored to specific industrial requirements, providing a versatile and cost-effective solution for a wide range of applications. The MDD 021, MDD 025, and MDD 041 models are designed with a slim profile and high power density, making them ideal for precision tasks in confined spaces such as screwing and operating auxiliary axes or tool changing devices. For tasks that require a high level of dynamism, such as in roller feeds for pressing, punching, and nibbling machines, the MDD 065, MDD 071, MDD 093, and MDD 115 models are the go-to options due to their exceptional power density. Lastly, for applications that demand extreme precision and synchronization, such as in grinding machines, the MDD 090 and MDD 112 motors are particularly suited, offering the precision needed for such high-precision tasks.
