Product Description:

The SG-B3.150.024-14.010 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. It is intended for closed-loop positioning and speed control tasks that require precise movement of conveyors, tooling tables, or gantry axes. By converting drive current into controlled torque across a wide speed range, the motor provides the mechanical connection between an electronic servo drive and the actuated load. Its synchronous design supports repeatable motion when paired with a compatible controller and feedback system.

The motor has a nominal shaft speed of 2700 rpm, providing a reference point for matching gearing and machine cycle times. At standstill, it can generate 16.6 Nm of torque for stationary or high-friction loads. Producing this torque requires a standstill phase current of 18.2 A, which should be considered when selecting the inverter and conductor sizes. A torque constant of 0.93 Nm/A relates commanded current to generated torque, supporting current-loop control by the drive. The rotor has a moment of inertia of 1.15 × 10^-3 kg·m², allowing responsive acceleration while helping to limit minor speed fluctuations. Mechanical mounting uses an IEC rectangular flange measuring 140 mm, allowing the motor to fit machine interfaces designed for this flange size.

An integrated holding brake secures the shaft during a loss of power with a clamping torque of 25 Nm. Its release coil is rated at 24 V DC and consumes 24 W while energized. The brake module adds 1.3 kg, while the motor assembly has a mass of 12.1 kg. The shaft can withstand a maximum axial load of 200 N. It has a diameter of 24 mm and a 50 mm keyed section for coupling to the driven equipment. The motor has a total length of 220 mm when the brake is excluded, which must be considered separately from the space required by the installed brake assembly.
