Product Description:

The MDD093A-N-020-N2M-110GR1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current from an inverter into precise rotary motion required for positioning axes and process lines in industrial automation. Instead of an internal resolver, the motor uses an absolute encoder, and the housing follows the standard frame style used across this series so it fits directly onto prepared machine frames.

At standstill, the rotor can deliver 9.2 Nm of continuous torque, which indicates how much static load the axis can hold without overheating. During operation, the rated mechanical output is reached at a nominal speed of 2000 rpm; this speed-torque point guides gear ratio selection and drive sizing. Position feedback is supplied by an integrated multiturn absolute encoder, allowing the controller to read the true shaft angle even after power loss. That data is communicated through Digital servo feedback (DSF), a serial protocol that reduces noise pickup over long cable runs. For vertical or overhung loads, a blocking brake is built in and can lock the shaft with 11 Nm of holding torque when power is removed. The motor follows size code 093 and length code A, giving it a compact package while standard balancing keeps vibration low in high-speed service. A standard housing simplifies heat transfer to the machine frame.

Mechanical integration is aided by a centering pilot of 110 mm, which helps ensure repeatable alignment on mounting flanges. Power and feedback leads exit to the right, and terminations are made through a connector for quick cable changes. The drive face carries a plain shaft in a standard single-ended configuration, so no side B extension is provided. A durable shaft seal is installed to block coolant or dust from entering the bearing chamber, and the assembly keeps its standard static balance without additional counterweights.
