Product Description:
The SG-B3.150.024-00.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. It serves as a rotary actuator in automation lines that demand repeatable positioning and velocity control, translating drive commands into precise mechanical motion for gantries, pick-and-place heads, and packaging spindles. Its permanent-magnet construction supports responsive torque production across changing motion profiles. Resolver feedback allows the drive to monitor rotor position and maintain closed-loop control during acceleration, steady operation, and deceleration.
The motor has a nominal speed of 2700 rpm, providing the rated shaft velocity for continuous operation under the appropriate load conditions. At standstill, it can exert 16.6 Nm while drawing a phase current of 18.2 A. This stall capability allows the energized motor to hold a static load through drive-controlled torque, although a separate brake may still be required when power is removed. The torque factor is 0.93 Nm/A, indicating the amount of torque produced in relation to the supplied current. A rotor inertia of 1.15 × 10-3 kg·m² supports responsive acceleration while maintaining stable motion. The 220 mm housing length accommodates the winding stack and the two-pole resolver that transmits rotor-angle feedback to the drive.
The motor uses a 140 mm flange diameter machined to accuracy grade N, supporting precise alignment with the mounting surface. Its Ø24 × 50 mm shaft with a keyway provides positive engagement with compatible pulleys, gearboxes, or rigid couplings. The supplied feather key measures 8 × 7 × 40 mm and matches the shaft interface. An enclosure rating of IP65 prevents dust from entering the housing and protects internal components against water jets, allowing the motor to operate in areas exposed to moisture or routine washdown. The motor has an overall mass of 12.1 kg, which supports secure installation without placing excessive weight on the machine frame. Proper mounting and coupling alignment help limit vibration and reduce unnecessary loading on the shaft and bearings.
