Product Description:

The SG-B3.150.024-03.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. This rotary unit is intended for closed-loop positioning and velocity tasks in industrial automation where quick response and repeatable motion are required. It converts drive current into controlled mechanical torque that moves machine axes, and its integrated brake lets vertical or overhung loads remain stationary when power is removed.

At its nominal speed of 2700 rpm, the motor can deliver continuous rotation that aligns with typical packaging or material-handling cycle rates. A standstill torque of 16.6 Nm defines the available static holding force, while the standstill current requirement of 18.2 A indicates the electrical load the drive must furnish to produce that torque without movement. The electromagnetic coupling is characterized by a torque constant of 0.93 Nm/A, so drive controllers can predict output torque from measured phase current. Dynamic behavior is influenced by the rotor inertia of 1.15 × 10⁻³ kg·m²; this moderate inertia allows rapid acceleration yet provides enough mass for speed stability during small load disturbances.

A protection rating of IP65 means the housing resists dust ingress and low-pressure water jets, so the motor can be cabinet-mounted or exposed on machinery frames without additional covers. The square mounting flange measures 140 mm across, and a featherkey measuring 8 × 7 × 40 mm transmits torque to couplings or gearboxes through the shaft, which is 24 mm in diameter and 50 mm long. Combined with the small integrated brake, overall length reaches 235 mm and total weight with the brake is 12.9 kg. The permissible axial load of 200 N supports belt tensioners or light thrust loads while maintaining bearing life.
