Product Description:

The SE-B2.030.060-10.015 synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the SE Synchronous Servo Motors series. It serves as a rotary actuator for automation axes that demand precise position and velocity control, such as pick-and-place stations, indexing tables, and compact robotic joints. When paired with a digital drive controller, the motor converts electrical power into tightly regulated mechanical motion so loads follow programmed profiles without appreciable overshoot. Its synchronous design supports repeatable acceleration, deceleration, and positioning under changing load conditions.

The motor has a nominal shaft speed of 6000 rpm and can deliver a static torque of 3.0 Nm. The drive may draw a peak phase current of 45 A during rapid acceleration. Every ampere of phase current produces approximately 0.43 Nm/A, while the 14-turn stator has a winding inductance of 14.0 mH that smooths the pulse-width-modulated voltage from the inverter. Standstill current is 7.5 A, while a voltage constant of 45 V per 1000 rpm works with the 1.8 V per 1000 rpm tachogenerator signal to support speed feedback. The rotor inertia is 0.60 × 10⁻³ kg·m², which supports fast reversals in applications with frequent direction changes. The round shaft is supplied without a keyway, allowing it to connect through a suitable clamping coupling.

The phase resistance is 2.25 Ω, supporting precise current regulation by the connected drive. Current rises to its commanded value with an electrical time constant of 6.1 ms. The motor responds to speed commands with a mechanical time constant of 7.5 ms, making it suitable for high-bandwidth position loops. Its thermal time constant is 19 min, allowing intermittent overload operation while helping the winding remain within its permitted temperature range. A connection cross-section of 1.5 mm² accommodates standard servo cables and limits voltage drop during rapid current changes. Proper cable sizing and secure connections help preserve the motor’s electrical response when it operates near peak current.
