MDD093B-N-030-N5M-110PA2

Product Description:

Bosch Rexroth Indramat manufactured the MDD093B-N-030-N5M-110PA2. The 3000 min⁻¹ speed of the Bosch Rexroth Indramat MDD093B-N-030-N5M-110PA2 synchronous motor is the rotational frequency that can be achieved under rated voltage and load conditions. In other words, this is the angular velocity when the applied AC frequency and the motor’s internal magnetic fields are in sync. The nominal speed is a key design element as the synchronization depends on the frequency of stimulation and the number of pole pairs. In automation where speed consistency is linked to process accuracy, a constant nominal speed enables precise motion control. This motor’s torque characteristics show how it performs statically and dynamically under temperature and electromagnetic constraints. Thermal dissipation methods have a direct impact on electromagnetic force production as shown by its continuous standstill torque of 14.5 Nm and up to 20.0 Nm with extra surface cooling.

This static torque is important for applications like lifts, presses and actuators that need to be able to support loads. By increasing torque through cooling the motor’s thermal saturation limits and the efficiency benefits of heat dissipation are shown. The motor’s safe working envelope is further defined by its electrical and thermal ratings. The motor’s thermal current carrying capacity before overheating limits are reached is shown by the continuous current at standstill of 24.1 A and up to 33.2 A with cooling. This current immediately contributes to the creation of electromagnetic fields which in turn produces torque. The peak current rating of 108.2 A is the absolute maximum for transient situations like acceleration or load shocks and sets limits for inverter design and protective circuitry. These values are closely related to the motor’s inductance (4.4 mH) and winding resistance (0.43 Ω at 20 °C) which affect power loss and control loop dynamics.

The MDD093B motor’s mechanical and environmental robustness is also designed in. The motor’s response to speed commands is directly influenced by its rotor moment of inertia which is 29×10⁻⁴ kg·m². This is important for applications that require frequent starts, stops or direction changes. A balance between torque stability and dynamic response is achieved with this low inertia. The 16.5 kg weight of the motor slows down the temperature increase while it’s running and provides physical stability. The motor has an IP65 protection rating which means it’s completely sealed against dust and water jets. The motor warms up slowly under load as shown by the thermal time constant of 50 minutes which is reduced to 45 minutes with surface cooling. The F-class insulation can withstand winding temperatures up to 155 °C. This defines the thermal operating window and the ambient operating range of 0 to 45 °C.
