Product Description:

The MDD041C-N-100-N2G-050PA1 is produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise rotary motion for positioning, velocity, and cyclic tasks in automated equipment such as pick-and-place heads or high-speed spindles. Its integrated blocking brake permits safe holding during power-off conditions, making the unit suitable for vertical axes or indexers that must maintain position when the drive is disabled.

This model can generate a continuous standstill torque of 2.05 Nm, meaning the shaft can sustain that torque indefinitely without overheating when cooled only by convection. The rotor can reach a nominal speed of 10,000 rpm, a high base velocity that supports short cycle times in lightweight mechanisms. A centering diameter of 50 mm provides the reference surface for concentric mounting, which helps keep the motor aligned with the driven assembly. Power and feedback are routed through a plug-in connector located on side A, allowing electrical installation from one direction. During emergency or commanded stops, the integrated brake develops 1.2 Nm of static torque so the axis remains locked until current is reapplied.

Rotor position is reported through resolver feedback, which supplies analog sine-cosine signals for high-resolution interpolation by the controller. The shaft is machined with a keyway, giving positive engagement with couplings or pulleys that must resist slip under dynamic loads. The motor includes a shaft seal that keeps lubricant in and airborne contaminants out. Internal construction uses standard balancing, which helps minimize vibration when the motor operates at rated speed. Additional design elements include standard housing geometry, motor length code C for an extended stator stack, and a single-ended shaft without a side B extension to conserve space.
