Product Description:

The MDD025C-N-100-N2G-040GR1 is a synchronous servo motor from the MDD Synchronous Motors series by Bosch Rexroth Indramat. This compact motor is intended for digital drive controllers that require precise rotary motion for positioning and speed-controlled tasks in industrial automation. Its standard housing and balancing arrangement support consistent integration with compatible machine components. The built-in blocking brake lets the axis hold position when the controller is disabled, which is useful when the load must remain fixed during a stop or power loss.

The motor develops a continuous standstill torque of 0.90 Nm, providing stable force for low-speed operation and static load holding without excessive heat rise. At rated conditions, it can reach a nominal mechanical speed of 10000 rpm, which supports fast indexing cycles in compact machinery. When power is removed, the integrated brake supplies 1.0 Nm of holding torque to keep the shaft from moving. Rotor balance is graded as Standard, helping the motor run smoothly within its intended operating range. The motor size is 025, which places it in the small-frame group used for compact servo axes where limited installation space is important.

A centering diameter of 40 mm helps maintain accurate alignment with flange plates or gearboxes during mounting. Power and feedback connections exit on the Right side of the endbell, and the power lead uses a plug-in Connector for straightforward cable attachment. Rotor position feedback is provided by a resolver for closed-loop control, and the fitted shaft seal helps limit lubricant escape and the entry of airborne contamination at the shaft interface. The shaft uses the standard single-ended layout, and the C length code places the motor in the medium stack length for this frame size.
