Product Description:

The MDC3.30B/SSA-1/S031 is a permanent-magnet DC motor engineered by Bosch Rexroth Indramat as part of the MDC DC Motors series. It is intended for servo-grade positioning tables and material-handling axes that require smooth, controllable rotation. The totally enclosed, non-ventilated housing eliminates the need for external ventilation, and the internal tachogenerator supports closed-loop velocity control.

Its continuous output parameters are anchored by a nominal armature current of 33 A, which yields 26 Nm of torque under steady duty with TENV cooling. A magnetic coupling factor of 0.80 Nm/A links torque to current, and the generated back-EMF coefficient of 84 V/KRPM establishes the speed-to-voltage relationship for the controller. Electrical responsiveness also benefits from 0.50 mH inductance and 0.15 Ω resistance in the armature, while reliable operation is maintained in ambient temperatures up to 45 °C.

For rapid indexing moves, the winding endures a 300 A pulse without demagnetization, and the insulation system permits a maximum armature potential of 170 V. Thermal accumulation is delayed by a generous iron mass that produces a 220 min thermal time constant, enabling cyclic overloads before steady heating occurs. Integrated tachogenerator feedback delivers 33 V/KRPM, features 60 Ω internal resistance, supports 15 kΩ loads, and limits ripple to 0.5%, supplying clean speed data to the drive.

Wake Industrial stocks this motor for immediate order fulfillment. Same-day shipping options can be arranged on qualifying orders, which helps reduce delays when a failed axis must be returned to service quickly. Quotations remain valid for 30 days to support budget reviews and purchasing workflows for maintenance planning teams.
