Product Description:

The SE-B2.030.060-10.037 synchronous servo motor is manufactured by Bosch Rexroth Indramat as part of the SE Synchronous Servo Motors series. Designed for industrial automation, it provides closed-loop speed and position control in pick-and-place units, indexing tables, and compact handling axes. It converts drive current into tightly regulated shaft torque for repeatable motion sequences.

Mechanical integration is straightforward because the motor uses a 100 mm square flange and a Ø14 × 30 mm keyed shaft to couple with gearheads or load spindles. This layout supports accurate alignment and helps minimize axial misalignment during installation. Despite that compact interface, the housing measures only 254 mm in length, so it fits into shallow machine enclosures. During operation it can reach 6000 rpm, and short duty windows allow a peak output of 7.8 Nm, exceeding the 3.0 Nm static holding figure. Commanded drive current starts at 7.5 A for standstill torque and may rise to 45 A when rapid acceleration is requested. The electromechanical conversion ratio is set by a 0.42 Nm/A torque constant, while electromagnetic back EMF develops at 45 V/1000 rpm. The winding inductance of 14.0 mH and copper resistance of 2.25 Ω shape current loop bandwidth and influence how the motor responds to the inverter.

Fast current response stems from an 6.1 ms electrical time constant and a rotor inertia of 0.60 × 10⁻³ kg·m². These values let the system follow rapid command changes without excessive overshoot and support quick speed correction after load variations. Heat accumulation is moderated by a 19 min thermal time constant, and the 7.6 kg mass helps slow temperature rise during cyclic loading. That behavior supports repeated operation over longer runs when the motor is used within its drive and load limits.
