Product Description:
The MDD090B-N-020-N2M-110PL2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for integration with digital drive controllers, the unit converts electrical command signals into precisely regulated mechanical rotation for positioning tables, pick-and-place axes, or packaging stations. Its standard housing and internal construction allow direct coupling to gearboxes or load shafts while maintaining the mechanical tolerances required in automated production cells. This type of motor is suited to applications where the control system must regulate torque, speed, and position through repeated operating cycles.
A centering pilot of 110 mm aligns the flange, and standard balancing limits residual vibration during high-speed operation. Electrical terminations are routed on the left side, and the power and feedback lines connect through a rugged connector, which helps when several axes are installed close together. At rest, the motor can exert 7.2 Nm of continuous torque, allowing static load holding without overheating. Under command, it reaches a nominal speed of 2000 rpm, which matches drive algorithms that rely on predictable speed-torque behavior. The motor has size 090 and length code B. Its standard housing dissipates heat by natural convection, so no separate cooling fan is required. A factory shaft seal also helps protect the front bearing area from coolant splash.
The blocking brake supplies 11.0 Nm of torque to secure vertical axes when power is removed, while a shaft with a keyway transmits motion to pulleys or couplings without slippage. Position data is returned through digital servo feedback (DSF) from an integrated multi-turn absolute encoder, allowing the drive to retain absolute rotor angle after shutdown. This arrangement supports applications that need position information immediately after startup instead of requiring a homing cycle each time power is restored. The shaft seal helps limit ingress at the front end. The shaft end is provided only on side A, leaving the opposite side free for other machine elements.
