Product Description:

The MDD090A-N-030-N2L-130GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as the rotary actuator in digital drive controller systems, converting commanded current into controlled torque and speed for positioning tables, gantry axes, and light-duty spindles. This arrangement lets the motor translate numerical control commands into repeatable mechanical motion during automated assembly and machining tasks. When used with a compatible controller, it supports closed-loop motion that keeps velocity and position stable as process loads change. Its synchronous design also supports responsive acceleration during repetitive production cycles.

This model provides a continuous standstill torque of 3.7 Nm, which allows the energized axis to resist load movement at zero speed. Under rated excitation, the rotor reaches 3000 rpm, giving the motor a practical operating speed for medium-inertia applications. Mounting accuracy is supported by a 130 mm centering diameter, while all power and feedback leads exit on the right side to keep cable routing clear of moving machine members. Position information is returned through digital servo feedback, allowing the connected drive to correct speed and position errors during each control cycle. That feedback channel also lets the drive monitor rotor position continuously without a separate external measuring device on the machine.

A bayonet-style connector allows quick disconnection for service access, and the blocking brake supplies 6.5 Nm of static torque to hold vertical or suspended loads when power is removed. The output interface uses a plain shaft with an integral shaft seal that helps limit lubricant leakage and contamination entry. The motor uses size code 090, and it has motor length code A for a compact housing. Dynamic balance is standard, the cast-aluminum housing uses standard cooling, and the shaft is single-ended without a side B extension. The compact housing is useful where adjacent axes, guarding, or tooling leave limited mounting space.
