Product Description:

The MDD041A-N-100-N2G-050GB0 is a permanent-magnet synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to operate with digital drive controllers, the unit converts regulated current into precise rotary motion for indexing tables, packaging spindles, and other light-duty axes within automated lines.

It features a centering diameter of 50 mm, allowing concentric mounting to machine frames while maintaining repeatable alignment. During stall conditions the motor can deliver 0.64 Nm of continuous torque, so a drive can hold a load without exceeding thermal limits. A nominal speed rating of 10000 min⁻¹ provides considerable velocity range when the controller modulates frequency. Electrical terminations are oriented on Side B, a layout that keeps feedback and power connectors away from the driven shaft side to simplify cable routing. Position and velocity data are returned through resolver feedback, giving analog sinusoidal signals that the drive converts into absolute rotor angle for closed-loop regulation. A keyed circular connector carries both phase power and resolver conductors, shortening installation time in multi-axis cabinets.

Dynamic behavior is supported by standard balancing, which keeps residual vibration low at the declared speed class. The compact stator is identified by an A length code, and the frame’s 041 motor size keeps mass and inertia small enough for quick acceleration. Environmental protection is improved with a shaft seal, preventing lubricant from leaving the housing and blocking external contaminants from entering the bearing seat. For hold-off applications the motor is supplied without a blocking brake, so designers must apply mechanical clamping or drive torque if power-off holding is required; a plain shaft and standard housing complete the mechanical configuration.
