Product Description:

The MDD090A-N-020-N2L-110PL0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as an electromechanical actuator in CNC machines, packaging lines, and handling systems where the drive controller issues digital setpoints. Inside the compact frame, permanent magnets on the rotor generate torque in proportion to stator current, enabling precise speed and position loops. Its compact servo design supports quick response to command changes during coordinated multi-axis motion. The unit’s mechanical interface follows standardized dimensions so it fits common machine layouts with minimal mounting changes.

In operation, the motor reaches a nominal speed of 2000 rpm, a value chosen to match common ball-screw lead rates and gear ratios used by the Indramat drive platform. At standstill, it can deliver a continuous torque of 3.7 Nm without exceeding winding temperature limits during continuous duty. Accurate centering on the machine plate is supported by a 110 mm pilot diameter, which helps reduce radial runout during repeated cycles. Power and feedback conductors exit on the left side so cable routing can remain consistent across a line of identical axes. A sealed connector carries both motor phase and encoder channels, reducing the number of separate connection points. Velocity and position data are transmitted through digital servo feedback, allowing the controller to close loops with high resolution and low latency.

The rotor shaft uses a standard keyway so couplings can transfer torque without slippage. A factory-installed shaft seal helps protect the front bearing area and restrict lubricant migration during machine operation. The sealed shaft end also helps when occasional splash reaches the drive end of the motor. Because the motor is supplied without a blocking brake, holding force must be provided externally when power is removed. This arrangement reduces rotor inertia and suits applications that already use mechanical clamping or vertical counterbalancing.
