Product Description:
The SE-B2.030.030-14.005 synchronous servo motor, manufactured by Bosch Rexroth Indramat, has a nominal speed of 3000 rpm. This speed serves as a standard for continuous-duty performance as it specifies how quickly the motor turns under constant mechanical load and voltage. The motor's rated static torque of 21 Nm is the most torque it can withstand while it is not moving, which is crucial in situations when the shaft has to be securely held in place. This becomes particularly crucial in configurations where the motor shaft is under pressure from gravity or outside forces when the system is stationary. Static torque isn't only a technical number in these situations; it's what maintains the stability and security of the overall system. This also has an impact on starting performance, how well the motor can start motion by overcoming inertial resistance and static friction. The motor’s torque constant of 0.92 Nm/A makes closed-loop current control schemes easier by providing a linear and predictable torque response to the input current.
The maximum torque of 57.4 Nm, which can be achieved with SM 35/70 controller, is the torque limit of the motor. This peak value is useful for fast acceleration or for overcoming transient resistance spikes and is the maximum instantaneous torque the motor can produce under certain conditions. Peak torque is important in servo control applications where speed and direction change rapidly, like indexing tables or pick-and-place systems, but cannot be sustained forever. The SE-B2.030.030-14.005 is electrically characterized by a winding inductance of 6.2 mH and a winding resistance of 0.51 Ohm. These values determine the power losses during current flow and the rate of current change under dynamic conditions. For building responsive control loops, the electrical time constant of 11.9 ms is a time domain measurement of how fast the current stabilizes after a voltage step.
The motor balances torque and angular acceleration in real time by resisting sudden changes in rotational velocity with its mechanical moment of inertia of 4.98×10⁻³ kg·m². By locking the motor shaft when de-energized and preventing accidental motion, the holding brake, which operates at 24 ±10% V and provides 18 Nm of brake torque, improves safety. This motor has a high-performance electrical and mechanical profile for demanding fast response automation applications. Its peak current is 158 A, and its ramp-up time is 32 ms. Assuming proper thermal management and ventilation are in place, its allowed ambient temperature range of 0°C to 40°C ensures operation in most indoor industrial environments.
