Product Description:

The MDD071C-N-040-N2T-095PB0 synchronous motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers, giving closed-loop torque and velocity control to automated transfer stations, pick-and-place gantries, and other industrial axes. The C-length frame sits between the smaller 071 variants and larger high-power models, so machine layouts can balance inertia and footprint without changing the overall servo architecture used with Indramat drive amplifiers.

A centering pilot of 95 mm aligns the housing precisely with gearbox flanges or mounting plates, and standard dynamic balancing minimizes vibration at high speed. The motor can deliver a continuous standstill torque of 6.6 Nm, allowing sustained force on static loads without thermal overload. With a nominal shaft speed of 4000 rpm, it supports rapid indexing cycles common in packaging or electronics assembly. Rotor position is monitored by an integrated multiturn absolute encoder; this device stores multiple revolutions, enabling absolute positioning after power loss. The encoder works with digital servo feedback (DSF), so the controller receives high-resolution data for tight speed loops, smoother motion profiles, and quicker recovery from disturbances.

Electrical connections are routed on Side B, which helps keep cables away from moving machine members and simplifies access to the rear connector block. The unit is shipped without a blocking brake, so any holding function must be provided by the drive or external locking elements. A shaft with a keyway transmits torque through conventional keyed couplings, and a front shaft seal helps prevent lubricant migration into the winding cavity. The internal stator depth follows the C length code, giving extra stack height over shorter versions for improved continuous power.
