Product Description:
Bosch Rexroth Indramat manufactured the SE-B2.030.030-14.015. The SE-B2.030.030-14.015 synchronous servo motor has a nominal speed of 3000 rpm, which is a key factor in motion control precision and cycle time in automation. Since it’s the reference speed for the motor’s mechanical output in terms of rotational speed, this speed (measured under load) is crucial for system responsiveness and process efficiency. The fast acceleration from standstill to full speed is made possible by the high torque/inertia ratio and the 23ms ramp-up time. The 0.6×10⁻³ kg·m² moment of inertia of the rotor allows for a fast response to torque input, especially in high-speed indexing or robotic applications. The torque characteristics of this motor define its mechanical capabilities. For applications that need static forces or gravity loads, the 4 Nm static torque is essential since it holds a position at a standstill.
It can handle high dynamic loads and accelerate rapidly without losing control or synchronization, thanks to the 9.7 Nm maximum torque. This dynamic range allows for reliable operation under various load conditions, reduces dwell time, and increases cycle time. Torque production, which is linked to current input, is controlled by the torque constant of 1.14 Nm/A, which determines the motor’s electromechanical efficiency. For current-driven torque modulation, the motor design provides a wide bandwidth, stability and surge capacity for sudden operational changes. The maximum current is 21 A, and the standstill current is 3.5 A. On the electrical side, the motor’s voltage constant, which is the back-EMF generated during rotation, is 116 V/1000 rpm. This is important for drive system design, especially for feedback-based voltage regulation and speed control.
The electrical time constant of 7.3ms shows fast current stabilization in the motor windings when the voltage is changed. Winding resistance (9.5 Ohms) and inductance (82 mH) determine the resistive and reactive behavior of the stator windings and impact power loss (I²R) and dynamic current regulation. Their ratio affects thermal efficiency and control loop performance, which in turn affects the electrical time constant. Energy efficiency and electrical noise filtering are balanced in high-frequency switching scenarios by reducing resistance while keeping enough inductance. Thermal and environmental requirements complete the motor’s constraints. The thermal time constant of 18 minutes, which is very low, shows that the motor can handle big loads without overheating as long as there is enough cooling. The voltage ripple tolerance is specified at ≤1.5% to minimize torque ripple and provide smooth operation under different supply conditions. The ambient temperature limit of 40°C defines the thermal envelope for safe operation; thermal stress above this might damage the bearings and insulation.
