Product Description:

The MDD090A-N-040-N2L-110GR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is used with digital drive controllers and converts electrical input into controlled rotary motion for positioning, conveying, or spindle duties in automated machinery. Because the motor is intended for controlled axis service rather than simple constant-speed duty, it suits transfer systems, feeders, and machine spindles that depend on repeatable acceleration and deceleration. This arrangement allows the paired drive to regulate torque and speed closely during repeated motion cycles, approach moves, and accurate stops.

The rotor is balanced to a standard grade, and at standstill the unit can develop a continuous torque of 3.7 Nm, which supports steady holding force during dwell periods. A built-in blocking brake supplies up to 11.0 Nm so vertical loads can remain secured after power is removed. During operation, the shaft reaches a nominal speed of 4000 rpm, matching applications that require short cycle times and quick repositioning. This speed range gives the paired controller room to combine fast travel with controlled low-speed motion during approach and hold phases. Position and velocity feedback are provided through digital servo feedback (DSF), which returns motor data to the controller for closed-loop regulation. Accurate mechanical alignment is aided by a 110 mm centering diameter, and motor length code A indicates the short frame.

All power and feedback plugs exit on the right side, which can simplify cable routing when conduits run along the machine base. Grouping the cable exit on one side helps keep surrounding machine spaces less crowded and reduces the need to route harnesses around the back of the motor. The rotor uses a plain shaft, enabling direct clamping of couplings without keyways, and a factory-installed shaft seal helps keep lubricants and coolants away from the bearings. Within the MDD hierarchy, the motor is size 090, and it is supplied without a side-B shaft extension. The connectors are arranged on the rear face of the housing, which helps keep the drive end clear for coupling components.
