MDD041B-N-100-N2K-050GA0
The MDD041B-N-100-N2K-050GA0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers where rapid positioning or stable speed control is required in automated machinery, pick-and-place heads, and light gantry axes. By combining a high pole-pair rotor with a compact magnetic design, the unit converts electrical commands from the drive into precise mechanical rotation for conveyors, feeders, or auxiliary spindles. This layout is well suited to repetitive start-stop motion in machines that need accurate response from a small motor package.
Mechanical alignment during installation is supported by the 50 mm centering diameter, and electrical terminations use a connection on side A for a clear cable path. The motor delivers a continuous stall torque of 1.35 Nm, and it can operate up to a rated speed of 10000 rpm. Position data are returned to the controller through resolver feedback, and an integrated absolute encoder supplements that signal for position tracking after power cycling. This feedback arrangement gives the drive the rotor information needed for commutation and controlled motion, while the size 041 housing with length code B keeps the mounting footprint compact.
Shaft integrity is maintained by a shaft seal that helps block coolant splash and airborne particles from reaching sensitive internal areas. The motor uses a plain shaft, so torque is transferred through external clamping elements rather than a keyed connection. Because it is supplied without a blocking brake, holding torque must be provided by the drive or by external locking hardware during power-off pauses. Dynamic balance is graded as standard, which helps limit vibration during acceleration and deceleration in normal operation.
