MDD041C-N-100-N2G-050FA1
The MDD041C-N-100-N2G-050FA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies rapid rotary motion to automated pick-and-place stations, small spindle drives, and indexing tables that demand frequent speed changes without sacrificing positional accuracy. The design follows the series' standard housing and balancing rules, so the unit fits modular drive systems used in automated equipment. That arrangement suits compact axes that need quick starts, stops, and repeatable reversals during short machine cycles.
The motor uses a centering diameter of 50 mm, which provides the reference surface for flange alignment against the machine frame. Power and feedback leads exit on Side A, so cable trays can be laid out on one side of the axis without crossover. A single circular connector handles both stator power and resolver lines, simplifying installation in tight spaces. At standstill, the motor can deliver 2.05 Nm continuously, which is important when sizing the associated drive for steady torque demand. During motion, the rotor reaches a nominal speed of 10000 rpm, allowing high throughput in light-duty positioning tasks while keeping inertial mismatch low.
A blocking brake rated for 1.2 Nm engages whenever the controller removes excitation, preventing back-driving on vertical or safety-critical axes. Position feedback is provided by a resolver feedback unit, which returns rotor angle information with good resistance to electrical noise and elevated temperatures. The motor uses a plain shaft profile so couplings or pulleys can be pressed on without keys, which helps reduce radial runout. Because the front end is finished without a shaft seal, the motor is intended for clean, dry enclosures where no coolant or lubricant can enter the bearing region. This arrangement is suited to indoor machinery where contamination control is handled by the surrounding enclosure rather than by the motor front end.
