Product Description:

The MDD093C-N-040-N2L-110PL2 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into precise rotary motion for axes in automated machining centers, packaging lines, and material-handling stations. A blocking brake is integrated for load holding during power-off states, and the housing is built for direct machine mounting. Its output uses a sealed shaft arrangement with a keyed drive interface so moderate radial forces can be carried while lubricant remains inside the motor. This layout suits positioning tasks that need repeatable motion and stable control during frequent start-stop operation.

Rated at 4000 rpm, the motor reaches its nominal operating speed under rated conditions. Power, feedback, and brake cables exit on the left side because the connection block is positioned there, which can simplify routing when several motors share a gantry. The brake can withstand 22 Nm of static torque so suspended loads can remain stationary without external clamps. Real-time rotor position is reported through digital servo feedback (DSF), enabling the drive to apply fine torque corrections with very fast response. This feedback arrangement lets the controller monitor rotor motion continuously rather than relying on coarse external sensing.

A centering diameter of 110 mm aligns the motor with the mounting plate and helps limit runout during high-speed cycles. Motor length code C gives this unit the longest stack in its frame, increasing active iron while keeping the outer dimensions unchanged. Frame size 093 sets the flange pattern used for this housing, and balancing remains at a standard grade for general machine duty. The motor uses a plug-in connector, which keeps the electrical interface compact at the housing. A shaft seal helps block coolant splash at the drive end, and the shaft is supplied without a side-B extension to keep the overall depth shorter.
