Product Description:
The SE-B2.040.060-14.000 synchronous servo motor is built by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It transforms electrical power into precisely regulated torque and speed for industrial motion applications. Actuators, pick-and-place heads, and feed tables can use this controlled rotary output to follow demanding motion profiles without mechanical gearing changes. When paired with a compatible servo drive, the motor supports accurate acceleration, positioning, and speed regulation throughout repetitive machine cycles.
This model reaches a nominal operating speed of 6000 rpm, providing high-speed positioning when commanded by a compatible drive. A continuous static torque of 4.0 Nm is available at standstill, while the steady standstill current is 10.0 A. The control loop can draw a peak phase current of 60 A during acceleration periods that exceed the continuous operating demand. With a torque constant of 0.42 Nm/A, each ampere delivered by the inverter contributes proportionally to shaft torque, which supports current-based control. The motor has an electrical time constant of 6.0 ms, allowing the winding current to respond quickly to drive commands. Its 1.40 Ω winding resistance and 9.4 mH inductance determine the current rise behavior. A voltage constant of 45 V per 1000 rpm indicates the back electromotive force that the drive must overcome as motor speed increases.
A rotor inertia of 0.75 × 10-3 kg·m² balances rapid speed changes with mechanical stability, and the overall mechanical time constant is 6.6 ms. The square flange measures 100 mm, providing a compact mounting interface for the machine frame. A keyed shaft measuring 14 mm in diameter and 30 mm in length supports positive engagement with gearboxes, pulleys, or rigid couplings. An integrated holding brake supplies 3.5 Nm of torque at rest. The brake operates from a 24 V DC supply and draws 0.11 A when energized. It allows vertical or suspended axes to remain locked without requiring continuous motor current, reducing heat generation while the axis is stationary.
