Product Description:

The MDD090C-N-040-N2M-110PR2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for mounting to digital drive controllers where it converts commanded current into regulated mechanical rotation for axes that require repeatable positioning and speed control in automated machinery. Its synchronous design supports accurate coordination with the drive during starts, stops, and speed changes, making it suitable for feed axes, indexing stations, and other closed-loop motion tasks.

At standstill, the motor can deliver a continuous torque of 10.4 Nm, allowing it to hold loads without overheating during static clamping cycles. Under rated operating conditions, it reaches a nominal speed of 4000 rpm, giving adequate headroom for fast indexing tasks while staying within the magnetic and thermal limits of the stator. Accurate centering during installation is aided by the flange's 110 mm locating diameter, which aligns the housing with the machine frame. Electrical power and feedback are routed through connections on the right side that use a single circular connector, simplifying cable runs along the machine enclosure. Output torque is transferred through a shaft with a keyway, ensuring positive coupling to pulleys or couplings without slip.

For safety during power loss, the integrated blocking brake supplies up to 11.0 Nm of holding torque, preventing back-driving on vertical or suspended axes. Motion feedback to the drive is provided by digital servo feedback (DSF) generated by an integrated multi-turn absolute encoder; this combination reports position over multiple revolutions and supports tight closed-loop regulation. The encoder arrangement lets the controller retain position data across multiple shaft revolutions, which helps maintain axis reference after restart. External contaminants are excluded by a shaft seal, so the internal bearings remain protected where coolant spray or dust is present. The sealed output end also helps protect internal components when the motor is installed near process areas that generate fine debris.
