Product Description:

The MDD093A-N-030-N2L-130PA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Supplied for use with digital drive controllers, it converts electrical commands from the drive into precise mechanical motion for positioning, contouring, and cycle-controlled duties on automated machine axes. The motor uses frame size 093 and length code A, making it suitable for applications that require repeated acceleration and deceleration while maintaining consistent servo accuracy through frequent start-stop cycles and directional changes.

Mechanical alignment is set by a centering pilot of 130 mm, which allows the flange to seat accurately against gearboxes or mounting plates. All power and feedback connections exit on Side A, and a molded connector supports quick disconnection during service while simplifying cable routing where access space is limited. The rotor is balanced to the standard class, which helps reduce vibration at the rated 3000 rpm nominal speed. Closed-loop regulation is aided by digital servo feedback (DSF), which sends position data to the drive for accurate speed and position control. When held stationary, the winding can produce 9.2 Nm of continuous torque, supporting moderate static loads without overheating during dwell periods.

A spring-applied, electrically released blocking brake is integrated and develops 11 Nm of static torque, so vertical or suspended axes can be secured when the drive is disabled. A radial shaft seal is fitted to help minimize lubricant migration, and the drive-side shaft has a keyway for use with standard compliant couplings. With only one shaft end, no mechanical projection is provided on side B, which can simplify enclosure layouts and leave more room around nearby components. The housing follows the series' standard cooling scheme, and the motor's mass distribution helps keep bearing loads low during rapid reversals and other high-cycle motion.
