Product Description:

The MDD093B-N-040-N2M-130PR1 synchronous motor is built by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. As a motor designed for digital drive controllers, it converts precisely modulated current from the controller into mechanical rotation for axes that require consistent velocity and position regulation in automated machinery. The unit uses a standard housing and standard dynamic balancing, so it can mount on common machine frames without additional vibration tuning. Its synchronous design supports predictable torque production across commanded speed ranges, which is useful in axes that must start, stop, and reverse with accuracy.

Mechanical fitment starts with a centering diameter of 130 mm, which aligns the stator housing with machine mounting surfaces to help maintain coaxial accuracy. Power and feedback lines terminate through a connector, and these ports are arranged on the right side of the housing to simplify cable routing when nearby components occupy the opposite side. This arrangement can reduce cable crowding in tight machine layouts and leave more clearance around adjacent assemblies. Under continuous stall conditions, the motor can sustain 14.5 Nm of torque without thermal overload, supporting static positioning or low-speed press cycles. When supplied at rated voltage, the rotor reaches a nominal speed of 4000 rpm, which suits fast indexing and short cycle times.

Load holding is provided by an internal blocking brake with 11 Nm of retentive torque, which helps prevent uncommanded motion when power is removed. Position data returns to the drive through digital servo feedback, and the signal is generated by an integrated multiturn absolute encoder so the axis can retain position information after restart. The brake and encoder support controlled holding at standstill and position reporting during repeated operating cycles. Torque is transmitted through a shaft with a keyway, which helps prevent slippage under cyclic loads. A shaft seal protects the bearings from coolant splash, making the motor better suited to machines where fluid exposure can occur during normal operation.
