Product Description:
The MDD041C-N-100-N2G-050MA1 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Its size 041 frame with length code C keeps inertia low for compact automation platforms, while the standard housing directs heat to the mounting surface without auxiliary cooling. Rotor balancing is performed to the standard grade so vibration stays within limits across the full speed range. Intended for direct connection to digital drive controllers, the unit converts commanded current loops into precise rotary motion that packaging, pick-and-place, or light machining axes can apply through belts, couplings, or ball screws. The compact format also suits installations where moving mass must be kept low and available mounting space is limited.
The motor develops a continuous standstill torque of 2.05 Nm, allowing it to hold or slowly move loads without overheating when the shaft is energized but stationary. Its regulated top velocity reaches 10,000 rpm, which supports high-speed operation in compact machine assemblies. A spring-applied brake rated at 1.2 Nm is fitted, and this blocking brake secures the axis during power loss or emergency stops. Position information is generated by resolver feedback, which provides analog sine-cosine signals for the drive. This feedback method supports smooth commutation and stable control during acceleration, deceleration, and rapid reversals.
Mechanical interfaces include a centering diameter of 50 mm, which simplifies alignment with flanges or gearboxes. Power and feedback connectors face side A, and the mating style is a connector, which helps keep electrical installation compact. The steel shaft uses a keyway for rigid torque transmission, and the opposite end of the motor housing remains closed. Because the unit is supplied without a shaft seal, it should be mounted in clean, dry areas or used with external sealing if coolant splash is expected. This layout supports straightforward cable routing while keeping the drive-side mechanical connection accessible.
