Product Description:

The MDD041C-N-100-N2G-050FB1 is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where regulated current is converted into precise rotary motion for compact pick-and-place axes, small spindle drives, and other high-speed positioning tasks in automated equipment. Its synchronous design supports accurate speed control and responsive positioning during repeated motion cycles. That makes it suitable for machinery that needs quick direction changes, stable low-speed control, and accurate stopping over short travel distances.

This motor reaches a nominal speed of 10000 rpm, giving the axis a wide operating range for fast moves and short cycle times. A continuous standstill torque of 2.05 Nm allows the motor to maintain load at zero speed within its thermal limits during pauses in motion. The centering diameter is 50 mm, which helps seat the motor accurately in compatible machine flanges. It uses a plain shaft and is supplied without a shaft seal, so it is best suited to clean, dry installation areas or to machines that provide sealing at the driven element. This combination is useful on compact mechanisms where mounting accuracy and low contamination risk are important. The motor also has standard housing and balance execution, and the C-length code indicates the corresponding stator stack depth for this frame size.

Electrical terminations are routed on side B of the stator and use a keyed connector set, which helps keep cable orientation consistent in multi-axis cabinets. Motion is monitored by resolver feedback, allowing the drive to maintain closed-loop speed and position control even under high dV/dt switching. For vertical or overhung axes, a blocking brake rated at 1.2 Nm engages automatically when power is removed to resist back-driving. The shaft end on the opposite side is omitted, which helps reduce overall length and rotating inertia while leaving more room around the motor body in tight layouts. The brake is especially helpful where gravity or external process forces could move the axis during a power loss.
