Product Description:

The MDD041A-N-100-N2K-050MA0 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a compact motor for digital drive controllers that delivers high-speed rotary motion to axes that demand tight velocity regulation. By combining a small 041 frame size with an A-length stator, the unit targets pick-and-place heads, light conveyors, and other low-inertia loads found in automated assembly lines. Its compact layout also suits mechanisms that need quick reversals and short travel distances, where low moving mass helps the drive respond cleanly to frequent start-stop commands.

This model sustains a nominal speed of 10,000 rpm, allowing fast positioning cycles, while its continuous standstill torque is 0.64 Nm, which is enough to hold fixtures without overheating the windings. A centering diameter of 50 mm simplifies concentric mounting to gearboxes or flanges. Power and feedback conductors exit on side A, and the interface uses a plug-in connector, so wiring can be routed into tight spaces without separate terminal hardware. Rotor mass is balanced to the standard grade, and heat moves through a ribbed housing without additional cooling channels. The integrated feedback device is an integrated absolute encoder that reports multi-turn position data directly to the drive, eliminating the need for external sensors. A resolver interface is also available for systems that use analog feedback loops, and the motor has a standard single-ended shaft.

Torque is transferred through a keyway shaft, letting couplings transmit motion without slippage during rapid acceleration and deceleration. Because the unit is supplied without a holding brake, machinery must rely on the drive’s static torque or an external mechanical lock to secure loads during power loss. The motor comes without a shaft seal, and its standard housing finish supports general indoor installation where sealing at the driven machine is provided separately. The cable outlet direction also helps keep wiring clear of adjacent modules in tightly packed assemblies.
