MDD041C-N-100-N2K-050PA1
The MDD041C-N-100-N2K-050PA1 is a synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is integrated into positioning and speed-regulated axes where compact dimensions and high rotational velocity are needed in automated production cells. It is typically used on servo axes that must accelerate, decelerate, and settle quickly during repeated machine cycles. The motor works with a digital drive controller so current, speed, and position can be regulated in a coordinated closed-loop system.
This model reaches a nominal speed of 10000 rpm, giving it the capability to follow rapid command changes while keeping cogging to a minimum. At standstill, it can deliver 2.05 Nm of continuous torque, so it can hold payloads without thermal overload during dwell periods. The front flange has a centering diameter of 50 mm, which simplifies alignment with standard machine mounts. Power and feedback conductors exit on side A through a single connector, which keeps external wiring compact. Standard dynamic balancing limits vibration, the housing uses natural cooling, and a shaft seal helps prevent coolant or lubricant ingress during operation. This combination suits compact installations where high speed is required without adding external cooling hardware.
An internal blocking brake provides emergency holding force rated at 1.2 Nm, allowing vertical or suspended loads to remain stationary when power is removed. Torque is transferred through a keyway shaft, and the feedback loop relies on resolver feedback for noise-resistant angle detection. The brake is intended for holding when the axis is stopped, while controlled motion remains the task of the paired drive system. The motor belongs to size code 041 and uses length code C, which suits installations where axial space is limited. A standard shaft end is present on the drive side only, eliminating unnecessary overhang on the rear of the unit.
