Product Description:
The MDD090B-N-020-N2M-110GR1 synchronous servo motor is built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it provides closed-loop motion for positioning tables, packaging axes, and material-handling gantries in industrial automation. Permanent-magnet excitation, a standard housing, and electronic feedback allow the controller to modulate current precisely so rotor speed and torque follow commanded profiles without overshoot. This motor format is well suited to axes that require repeatable acceleration, stable speed control, and compact installation.
The motor supplies a continuous standstill torque of 7.2 Nm, meaning the shaft can hold that load without rotation while energized. The motor has a nominal speed of 2000 rpm, which is its rated operating velocity under thermal equilibrium and is suited to gears or direct drives that require moderate rotational speed. A centering diameter of 110 mm aligns the flange to the machine frame so runout remains minimal. Power and feedback conductors connect through a single connector, which keeps the connection point compact and reduces wiring complexity. Leads exit on the right, helping keep cable routing orderly and maintain proper bend radii. Standard rotor balancing and the B length code help reduce bearing stress during acceleration.
An internal blocking brake provides 6.5 Nm of holding torque, securing vertical or suspended loads whenever drive power is removed. Shaft position is reported by an integrated multiturn absolute encoder, allowing the axis position to remain available after power loss or an emergency stop. That position data is transmitted over digital servo feedback (DSF) lines to the controller for high-resolution closed-loop regulation. The output uses a plain shaft with a shaft seal to keep lubricant inside the housing and limit contaminant entry during continuous-duty operation.
