Product Description:

The SF-A5.0460.030-00.101 servo motor is produced by Bosch Rexroth Indramat within the SF Servo Motors series. This electronically commutated unit provides closed-loop rotary motion for positioning tables and packaging modules. It also supports other industrial automation axes that demand precise speed and torque regulation.

At its rated speed of 3000 min⁻¹, the rotor can synchronize with drive controllers to deliver continuous motion without mechanical resonance. The internal winding insulation permits a DC link voltage of 670 VDC, allowing the drive to extract high peak power from common 700 V intermediate circuits. A flange diameter of 190 mm matches standard gearboxes and accommodates the oil-tight output interface specified for this model; the sealing is suitable for supply lines that see up to 1 bar of oil pressure. Axial loads up to 380 N can be imposed on the Ø32 × 58 mm shaft without exceeding bearing limits, while a locked-rotor torque of 46 Nm keeps loads immobilized during startup or holding sequences. In such stall conditions, the drive may draw a locked-rotor current of 29 A. Temperature monitoring is handled by an embedded PTC thermistor that changes resistance between -5 °C and +155 °C to alert the controller before overheating occurs.

The mechanical layout follows the IM B5 construction, meaning the stator is footless and mounts to a machine wall through its front flange so shaft alignment remains rigid even when external couplings introduce vibration. Dynamic response is influenced by a rotor inertia of 166 × 10⁻⁴ kg·m², which balances fast acceleration with stability for medium-mass loads. Electrical torque production scales linearly with current thanks to a torque constant of 1.58 Nm/A, enabling the drive electronics to calculate required current commands without iterative tuning. The oil-tight sealing supports operation in lubricant-rich environments such as spindle drives or hydraulic pump stations while maintaining consistent positional accuracy.
