Product Description:

The MDD090C-N-020-N2L-110GR0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into rotary motion for positioning, feed-axis, and handling tasks in industrial automation lines. A standard housing and standard dynamic balancing level help the motor fit directly onto machine frames while keeping vibration within normal operating limits. It is suited for applications that need repeatable positioning and steady speed control during frequent start-stop cycles.

The centering pilot on the flange measures 110 mm, giving the assembly a locating surface that helps maintain concentricity between the motor and the driven equipment. Power and feedback lines exit on the right side, so cable routing can be planned around that orientation. A single connector carries the electrical interfaces and keeps the external connection point compact. Under continuous stall conditions, the electromagnetic system develops 10.4 Nm of torque, allowing stable holding or low-speed feed without overheating. When the inverter applies full rated frequency, the rotor turns at 2000 rpm, which suits moderate-inertia loads that still require smooth velocity control.

Feedback to the drive is provided through digital servo feedback, which supplies high-resolution position data for tight closed-loop control. Because the unit is supplied without a blocking brake, any axis that needs passive holding must rely on external clamping or drive-generated torque. The output end uses a plain shaft that mates with couplings or pulleys without keyways, which can help reduce stress concentrations during acceleration and deceleration. Protection at the output end is improved with a shaft seal, helping keep contaminants away from the bearing area. This arrangement supports use in packaging machines, printing lines, and modular transfer stations that run for long operating periods.
