Product Description:

The MDD090C-N-020-N2L-110PA0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts drive current into controlled mechanical rotation so positioning axes, gantries, and material-handling stages follow commanded motion profiles in automated machinery. The unit uses a 090 frame size with length code C, placing it in a medium-power format that shares mechanical interfaces with other motors in the same series. This layout suits general-purpose servo applications that require accurate speed and position control without moving to a larger frame.

At standstill the motor can develop 10.4 Nm of continuous torque, allowing closed-loop holding force without overheating. During operation it reaches a nominal speed of 2000 rpm, a value suited to common machine spindle and feed rates used with compatible Indramat drives. A centering diameter of 110 mm helps align the motor flange with the driven load and reduce radial runout at the coupling. Position and velocity feedback are supplied through digital servo feedback (DSF), allowing the controller to monitor rotor motion directly during closed-loop operation. The housing is intended for protected machine installations where the motor is mounted inside an enclosure or another shielded space.

The electrical and signal connections exit on Side A, and a keyed industrial connector carries both power and feedback lines to simplify cable routing. Because the motor is supplied without a blocking brake, vertical or suspended loads require external holding force when power is removed. Torque is transmitted through a keyway shaft fitted with a shaft seal, which supports positive coupling while helping separate lubricants and contaminants at the shaft interface. Standard balancing permits direct coupling to belt pulleys or gears, and the shaft end is present only on the drive side, leaving side B without a second shaft extension to save space behind the motor.
