Product Description:

The MDD071C-N-060-N2T-095PR2 is a synchronous servomotor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts regulated electrical current into rotary motion for positioning and speed-controlled machine axes. This operating role suits automated equipment that requires steady torque response, accurate speed regulation, and repeatable motion. An integrated feedback system returns position data to the controller, allowing closed-loop operation without external sensors.

For mechanical coupling, the shaft uses a keyway, and the flange has a centering diameter of 95 mm so the rotor axis can be aligned accurately within the driven assembly. Under continuous duty at stall, the motor delivers 6.6 Nm of torque, which supports applications that need substantial low-speed force during holding or indexing periods. The windings and cooling arrangement support a rated speed of 6000 rpm when the connected drive, supply conditions, and load inertia allow it. Motion feedback is provided by digital servo feedback, which sends position and speed data to the drive without requiring a separate tachometer. The centering feature also helps the housing seat accurately on the machine face and reduces coupling misalignment during installation.

A blocking brake is fitted, and it provides 6.5 Nm of holding torque to keep vertical axes stationary when power is removed. Vibration is controlled by standard balancing, and the frame size is 071. A radial shaft seal helps protect the bearing area from coolant or dust entry, while the electrical and feedback connections are arranged on the right side for a compact cable layout. The motor uses length code C, and the shaft end does not include a side-B extension. Right-side connector placement can simplify routing where cables approach the motor from one direction, and the single output shaft end can make coupling layout more straightforward.
