MDD071B-N-040-N2T-095GL2
The MDD071B-N-040-N2T-095GL2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts drive current into controlled mechanical rotation for positioning and velocity loops in industrial automation cells. The unit uses a standard housing and standard rotor balancing, so it can be mounted directly into machinery without added vibration isolation. This arrangement suits transfer units, indexing mechanisms, and other axes that require repeatable motion during frequent start-and-stop operation.
This motor produces a continuous standstill torque of 4.4 Nm, which is the load it can hold continuously at zero speed without overheating. During rapid stops, the integrated blocking brake provides 6.5 Nm to hold the axis, and the brake releases automatically when motion resumes. At its rated operating point, the rotor reaches 4000 rpm, which supports fast cycle times in pick-and-place or indexing stations. Precise mechanical alignment is supported by a centering diameter of 95 mm, cabling exits on the left side, and the motor uses a plain shaft with a shaft seal. There is no secondary shaft on side B, which simplifies coupling arrangements and leaves the drive end focused on the main power transmission point.
Connection to the drive is made through a sealed connector that carries the power phases and the signals from the integrated multi-turn absolute encoder. Position data are transmitted through digital servo feedback, allowing the drive to monitor rotor location accurately during closed-loop operation. The encoder also supports commutation and stable speed regulation across the motor’s operating range. The motor has size code 071 and frame length B, placing it in a compact housing for general servo applications where reliable feedback and direct mounting are required.
