Product Description:
The MDD093B-N-040-N2G-110GA0 is a precisely developed servo motor designed for high-performance industrial applications by Bosch Rexroth Indramat. When powered by its rated voltage and frequency under typical load circumstances, this motor achieves its nominal speed of 4000 revolutions per minute, which is its precise rotational speed. Put more simply, 4000 min⁻¹ is the speed it will reliably sustain under typical operating conditions, giving it a reliable option for applications where accuracy and stability are essential. The motion profile of the load attached to the shaft is determined by this speed, which is measured in revolutions per minute. In precision-dependent applications like multi-axis robotic systems and CNC machining, it’s essential to respect the nominal speed to coordinate movement and maintain performance across cycles. The motor can withstand sudden direction changes, high inertia starts and unexpected frictional loads without stalling due to its peak current. However, these transients create thermal and electromagnetic gradients in the winding and magnet that must stay within the tolerance.
To use the maximum capacity without sacrificing the insulation class F, the drive’s current limiters and thermal models must be tuned. This insulation class provides a wide thermal headroom during severe cycles by allowing winding temperatures up to 155 °C. For torque, the motor is designed to deliver 45.1 Nm at peak current under optimal thermal and electromagnetic conditions. The current-based torque scalar is the torque constant of 0.40 Nm/A at 20 °C, which is the ratio of electrical input to mechanical output. This ratio is temperature-dependent, and the real-time torque output is influenced by magnetic flux density and resistance (0.20 Ω at 20 °C). The motor must absorb I²R losses caused by continuous currents of 36.6 A or 50.5 A when at a standstill to achieve this.
Electrically, the stator winding inductance, which is measured at 1.9 mH, controls the motor's resistance to abrupt fluctuations in current. In systems that use high-frequency switching, this inductance has a direct impact on how fast and precisely the torque responds to input signals. This value is essential in determining the electromechanical time constant, as is the rotor’s moment of inertia (2.9 × 10⁻³ kg·m²). When smoothness is more important than speed, a higher inertia will dampen high-frequency disturbances, delay acceleration and require more torque for the same motion. The motor can be used in harsh industrial environments due to its IP65 protection grade, which means neither dust nor water will affect any of these performance characteristics. When combined, these factors make for a well-balanced motor profile perfect for high-performance trial automation applications where environmental resistance, thermal endurance and control integrity are key.
