Product Description:

The MDD090B-N-040-N2L-110PA0 synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It serves as the rotary element in closed-loop automation, where digital drive controllers modulate current to produce precise torque and speed for indexing, conveying, and synchronized positioning tasks. The motor is intended for applications that require repeatable acceleration and stable speed regulation across changing loads. With its B length code and 090 frame size, the unit fits medium-power axes in packaging, printing, and general handling equipment while maintaining fast electrical commutation for coordinated multi-axis motion.

Mechanical output starts with a continuous torque at standstill of 7.2 Nm, giving the drive enough reserve to hold loads when stationary. During motion, the rotor can reach a nominal speed of 4000 rpm, which suits spindle and conveyor duties that need high-speed rotation. Accurate alignment to gearboxes or direct-drive flanges is helped by a centering diameter of 110 mm. Command and position data are exchanged through digital servo feedback (DSF), and power and signal cables lock to a front-mounted connector. This feedback arrangement lets the controller monitor rotor position directly during speed and positioning cycles. Standard balancing minimizes residual vibration, and the housing uses an uncooled design that relies on surface convection rather than forced air.

Field wiring approaches the unit from side A, so cable routing can be planned without crossover at the motor face. Cable entry at the front keeps the connection area accessible when the rear of the motor is close to a machine frame. The single-ended shaft uses a keyway for coupling, and a shaft seal helps block lubricant or dust from entering the bearing chamber. Because the motor is supplied without a blocking brake, holding force during power-off conditions must come from drive torque or an external clamp. The frame code 090 keeps the motor compact, and there is no shaft extension on side B, which helps reduce overall length in tightly spaced machine assemblies.
