Product Description:

The SG-B0.007.070-13.010 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. It functions as a compact rotary drive for automated pick-and-place units, feeders, and inspection tables, where fast response and accurate positioning are required. A brushless resolver is integrated for feedback, enabling the connected controller to track shaft angle and synchronize motion with the rest of the machine.

With a nominal speed of 6800 rpm, the motor suits applications that demand high rotational velocity while keeping heat rise under control. Its 55 mm square flange matches standard servo gearheads and simplifies installation on existing brackets. Installation follows the IM B5 mounting pattern, placing the pilot flange and threaded holes on the face for rigid coupling to the machine frame. A torque constant of 0.34 Nm/A describes the linear relationship between armature current and output torque, allowing drive tuning based on current limits. During locked-rotor operation, the phase windings draw 3.0 A, so the amplifier must supply that current at standstill, and the housing meets IP65 sealing so airborne dust and low-pressure water jets do not reach internal components.

The dynamic response is assisted by a rotor inertia of 0.022 ×10⁻³ kg·m², keeping acceleration times short without compromising stability. When the shaft is stationary, the motor can hold a load with 0.9 Nm of torque, and continuous static duty is rated at 0.95 Nm. The holding brake operates from a control voltage of 24 V ±10%, securing vertical axes when power is removed. Power transmission is through a Ø9 × 20 mm smooth shaft that mates directly with precision collets or clamp hubs, while class R flange accuracy maintains concentricity and the smooth surface avoids keyway backlash.
