Product Description:

Bosch Rexroth Indramat manufactures the SE-B3.075.030-10.000 within the SE Synchronous Servo Motors series. The motor uses an IM B5 flange-mount construction for secure attachment and accurate alignment with the driven machine. It is intended for closed-loop positioning tasks in packaging lines, assembly gantries, and conveyor drives where precise torque and rapid speed changes are required for repeatable machine cycles.

The motor attains a nominal shaft speed of 3000 rpm, and its control electronics can draw up to 57 A of peak phase current during acceleration bursts. Each ampere applied produces approximately 0.98 Nm/A of torque, allowing the drive to scale output linearly in current-regulated modes. Electrical response is characterized by a time constant of 10.2 ms, which indicates how quickly armature current settles after a setpoint change and influences servo-loop bandwidth. When transient loads demand more force, the electromagnetic system can deliver a maximum torque of 18.6 Nm before saturation. A separate mechanical time constant of 3.3 ms describes the effects of rotor inertia. The 30 ms ramp-up time to rated speed characterizes startup responsiveness under nominal load.

The static torque available at standstill is 9.3 Nm, so vertical axes can hold position without a brake as long as the drive maintains excitation at the standstill current of 9.5 A. The stator windings have an inductance of 21 mH and a resistance of 2.1 Ω; together, these values limit ripple current and determine copper losses during continuous operation. The housing carries an IP67 protection rating, permitting installation in washdown zones or dusty environments while maintaining the integrity of the internal insulation. A 32-minute thermal time constant indicates that the motor temperature rises gradually, providing additional capacity for cyclic overloads before thermal derating becomes necessary.
