SE-B2.030.060-05.000

Product Description:

Bosch Rexroth Indramat makes the SE-B2.030.060-05.000. The nominal speed of the Bosch Rexroth Indramat SE-B2.030.060-05.000 synchronous servo motor is 3000 rpm, which is a key kinematic characteristic for high-speed applications. The motor’s ability to move fast under rated load and voltage is determined by its rotational speed, which is the angular displacement per unit of time. The motor balances electromagnetic torque and inertial forces at 3000 rpm for reliable performance in applications where speed uniformity has a direct impact on cycle time and throughput, such as robotic assembly or conveyor systems. Kinematic errors can be introduced by deviations from this nominal speed, disrupting coordinated motion. The cross product of the Lorentz forces in the motor windings and the lever arm distance from the rotor axis is the maximum torque, or peak rotational force, of 57.4 Nm. The motor’s magnetic flux density and winding shape determine the torque constant, which is 0.92 Nm/A.

The motor’s transient electrical capacity is defined by its peak current rating of 158 A, which is the highest instantaneous current the windings can withstand without going above thermal or electromagnetic limits. Torque is proportional to the torque constant during acceleration by the strong magnetic fields created by the current surge. However, to avoid insulation degradation, thermal management is required due to the resistive losses (I²R) in the windings, which is 0.51 Ω. The electrical time constant (τ_el = L/R = 11.9 ms) introduced by the winding inductance of 6.2 mH controls the rise time of the current and the motor’s sensitivity to sudden voltage changes. A smaller τ_el is better for high-bandwidth motion control. For applications like vertical axis placement where gravitational forces need to be countered without constant energy consumption, the static torque of 21 Nm, which is maintained at a standstill, provides a reliable holding force.

How long the motor takes to equilibrate to operating temperature under load is determined by its thermal time constant of 35 minutes. By allowing heat to dissipate throughout the motor’s body, this slow thermal response delays critical temperature thresholds and allows for occasional overloads without damage immediately. The rotor’s mechanical resistance to angular acceleration is determined by its moment of inertia (4.98×10⁻³ kg·m²); lower values allow for faster speed changes, which are important for robotics or high-precision indexing. As the rotor cuts through the stator magnetic fields, Faraday’s Law of Induction connects the voltage constant (102 V/1000 rpm) to the electromotive force (EMF) to the rotational speed. The holding brake uses electromagnetic actuation to provide fail-safe shaft locking. It is rated for 18 Nm at 24 V ±10%. Its torque overcomes external or gravitational forces to provide static load holding, especially in vertical or safety-critical applications.
