Product Description:

The MDD090C-N-020-N2L-130PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts command currents from an electronic drive into controlled mechanical rotation for industrial axes that require position accuracy and moderate continuous torque. The motor fits multi-axis assemblies that use standardized mechanical and electrical interfaces for consistent integration. Its feedback and brake arrangement make it suitable for positioning tasks that need controlled stopping and stable hold behavior between motion cycles.

A centering pilot of 130 mm aligns the housing to the machine frame, and the power and feedback conductors exit on side B to suit rear cable routing. Electrical termination is through a connector, so the motor connects without fixed lead splices. Under continuous stall conditions, the rotor can hold 10.4 Nm of torque, and a blocking brake rated at 6.5 Nm secures the load when power is removed. Command signals are interpreted through digital servo feedback (DSF), so the drive receives high-resolution position data for closed-loop regulation. The motor has a standard housing and a single shaft end without a side B extension. This layout helps keep cabling close to the motor body and reduces interference with nearby machine components.

The motor has a nominal speed of 2000 rpm, which suits medium-speed axis motion in automated equipment. Internal rotor trim uses standard balancing, so the motor can run smoothly when coupled to precision mechanical components. The output shaft uses a keyway for positive torque transmission, and a shaft seal helps protect the front bearing from coolant splash and debris. Because the shaft is keyed and sealed, the front end can transmit torque while limiting contaminant entry at the bearing area. This configuration supports direct coupling to pulleys or gearboxes where secure torque transfer and sealed front-end operation are required.
