Product Description:

The SG-B3.100.029-13.010 is a motor produced by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. It is designed to deliver controlled rotary motion for positioning and velocity tasks in industrial automation lines, coupling directly to gearboxes, belt drives, or load shafts where precise closed-loop control is required.

The shaft reaches a nominal speed of 3500 rpm, and at standstill it can supply 11.2 Nm while drawing 15.6 A. These static figures reflect the electromagnetic conversion efficiency defined by the torque factor of 0.73 Nm/A. Responsiveness is supported by the short electrical time constant of 0.80 ms, so current rises quickly when the drive demands torque. A small integrated brake is fitted; its friction elements hold the rotor whenever control power is removed. Rotor position is returned to the drive by a brushless resolver, providing absolute angle data without commutation contacts. System power is rated at 2.5 kVA, and thermal design keeps the stator within limits during continuous operation. The motor’s 210 mm overall length and IM B5 flange mounting allow direct coupling to housings that follow IEC dimensions, while flange accuracy class R maintains face run-out tolerances.

Mechanical limits include a maximum axial load of 200 N, so thrust bearings in the driven mechanism must stay below this value. Environmental sealing meets the IP65 designation, preventing dust ingress and protecting against water jets when the shaft seal is correctly installed. The brake is released with a nominal coil voltage of 24 V, which matches the common control supply found in many machines. Total apparent power demand remains within 2.5 kVA, letting the drive panel size its fuses and cabling accordingly. Together, the rigid IM B5 interface, class R flange accuracy, and the 210 mm housing length simplify integration while the resolver feedback maintains consistent commutation under dynamic load changes.
