MDD041A-N-100-N2G-050GA0
The MDD041A-N-100-N2G-050GA0 is a small-frame synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Supplied as a motor for digital drive controllers, it is intended for fast positioning and speed control tasks in automated assembly lines, electronic component handlers, and light spindle drives. Its electrical design lets a compatible controller modulate stator current precisely, converting it into repeatable rotary motion for continuous duty or indexed moves.
A nominal speed of 10000 rpm supports rapid cycles, while a continuous standstill torque of 0.64 Nm provides adequate holding capacity for light fixtures without overheating. Accurate mechanical registration is assisted by a 50 mm centering diameter that aligns the standard housing during flange mounting. The motor returns position through resolver feedback, enabling commutation over the full speed range. Output power is delivered through a plain shaft, and a shaft seal protects the internal bearings from dust and coolant splash. Because the windings are arranged for low inertia, the rotor can reverse direction quickly, and the feedback device supplies rotor angle information to the drive so overshoot can be corrected within the control loop.
The rotor is trimmed to standard balancing, permitting operation at rated speed without supplemental correction weights, and the standard housing shares mounting dimensions with other 041-size units. Leads exit on side A, and a compact connector carries both power and feedback conductors, reducing enclosure penetration points. This layout keeps cable routing concentrated at one end of the motor, which helps in compact machine spaces. The motor is built without a blocking brake, so any power-off holding must be provided by the drive or an external clamp. Length code A keeps the stack short, and the single shaft end simplifies coupling while the shaft seal extends service life in lightly contaminated areas.
