Product Description:
The SE-B2.040.060-10.037 synchronous servo motor is manufactured by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It serves as a compact rotary actuator for industrial automation systems. The motor converts drive controller output into precise shaft movement for pick-and-place stations, gantry axes, and packaging machinery that require consistent velocity and repeatable positioning across extended duty cycles.
It delivers a nominal speed of 6000 rpm, allowing high throughput where rapid indexing is critical. At standstill, the motor can apply 4.0 Nm of torque, and its torque constant of 0.42 Nm/A supports current-based control loops. Dynamic events are supported by a peak phase current of 60 A, while routine excitation remains at the 10.0 A standstill current. The electromagnetic circuit reaches operating current with an electrical time constant of 6.6 ms. Its mechanical response has a time constant of 6.0 ms, so commanded speed changes propagate through the drive train with minimal delay. The voltage constant is 45 V per 1000 rpm for back electromotive force, and an integral tachogenerator supplies 1.8 V per 1000 rpm for velocity feedback.
The rotor inertia is 0.75 × 10⁻³ kg·m², balancing quick acceleration with stable load regulation. The motor has a mass of 8.8 kg and an overall length of 277 mm, allowing installation within compact machine layouts. Power is transmitted through a shaft measuring 14 mm in diameter and 30 mm in length, which accommodates compatible couplings. The stator windings have an inductance of 9.4 mH, which affects current ripple during operation. Their resistance is 1.40 ohms, an important consideration when matching the motor to a suitable drive. Thermal behavior is governed by a 25-minute thermal time constant, which indicates how quickly winding temperature responds to sustained loading. Continuous operation must remain within the applicable load and temperature limits to protect the windings from excessive heat.
