Product Description:

The MDD090A-N-020-N2M-130GR0 is a synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical power into controlled rotary motion for positioning tasks in automated machines. The design follows Motor Length Code A and the 090 frame size, giving a compact form factor that integrates easily into standard housings without auxiliary cooling components. This arrangement supports use in motion systems that require accurate control with a compact installation envelope.

At standstill, the unit supplies a continuous torque of 3.7 Nm, allowing it to hold loads without overheating when natural convection is the only cooling path. During operation, it reaches a nominal speed of 2000 rpm, setting the top synchronous velocity available to the axis. Accurate mechanical alignment is supported by a centering diameter of 130 mm on the mounting flange. Rotor position is relayed through digital servo feedback, enabling the drive to close position and velocity loops with high resolution. All power and signal conductors exit through a right-side connection that uses a quick-disconnect circular connector, which helps keep cable routing orderly. Standard dynamic balancing and a standard housing finish keep vibration and thermal behavior within normal limits.

The motor integrates a multiturn absolute encoder, so reference moves are unnecessary after power restoration. It is delivered without a blocking brake, which shortens the overall length when static holding torque is provided elsewhere in the machine. A molded shaft seal guards the bearings from splash fluids and dust to maintain the IP65 enclosure boundary. The output shaft is a plain shaft, and the opposite end remains closed in a standard single-ended shaft arrangement. Balanced to the standard grade, the assembly supports stable running at rated speed while the connector interface follows the series wiring layout. This combination supports consistent motion feedback and straightforward integration with compatible drive systems.
