MDD041B-N-100-N2G-050GA0

The MDD041B-N-100-N2G-050GA0 is a compact AC servo unit produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it delivers position and velocity control in automated machinery lines. The frame follows the 041 size and B length code, which defines its stator length and mechanical envelope for tight mounting spaces. When integrated with Indramat drive electronics, this unit converts commanded current into torque so that gantries, pick-and-place heads, or compact spindles follow precise motion profiles required in industrial automation.

Mechanical mounting and thermal capacity are defined by several parameters. A centering diameter of 50 mm aligns the flange to the machine face and keeps runout low. The continuous standstill torque of 1.35 Nm indicates the load the motor can hold indefinitely without exceeding its temperature rise. High-speed processes are supported by a nominal velocity of 10000 min⁻¹, so the rotor can deliver rapid cycle times when paired with the correct gearbox or direct-drive shaft. Cables exit on Side A, and the single plug-in Connector simplifies installation and service. Standard dynamic balancing and a standard housing complete the mechanical specification while keeping vibration and envelope size consistent across the series.

Signal acquisition relies on resolver feedback, giving analog absolute position data for closed-loop control even after power loss. The output shaft is a plain shaft with a keyless geometry, isolated from contaminants by a motor-integrated seal described as with shaft seal. Because the model is supplied without a blocking brake, holding torque must come from the drive or an external lock when the system is idle. The side-B shaft end is omitted, and the standard shaft-end format reduces mass while meeting general-purpose coupler designs, allowing the motor to complement light duty axes that require fast acceleration rather than high holding capacity.
