Product Description:
Bosch Rexroth Indramat manufactures the SF-A5.0460.020-04.000 servo motor within its SF Servo Motors series. Designed for precision positioning and velocity regulation, the unit works with compatible drive modules and single-turn encoder networks to close the motion control loop in automated assembly lines, pick-and-place stations, and forming equipment. It converts supplied three-phase power into regulated mechanical output, creating a compact rotary actuator for controlled axis motion. Integrated braking and feedback functions help reduce external hardware at the motor location while supporting repeatable operation in automated equipment. This arrangement supports accurate starts, stops, and speed changes across repeated production cycles.
The motor uses a 190 mm square flange and a 32 × 58 mm shaft, allowing direct coupling to medium-frame gearboxes or pulleys. Under continuous operation, the rotor turns at a rated speed of 2000 rpm, and each ampere delivered by the inverter produces about 2.2 Nm/A of electromagnetic torque. Acceleration behavior is influenced by a rotor inertia of 166 × 10⁻⁴ kg·m², which helps the drive respond predictably during speed changes. The overall length is 428 mm, so the installation must allow room for the motor body, cable routing, and airflow around the housing. The shaft dimensions support secure torque transfer when the motor is matched to appropriate couplings.
Holding duty is provided by a 56 Nm brake that operates on 24 VDC and draws 1.33 A, with release occurring in 97 ms for short cycle sequences. When the rotor is locked, the electromagnetic system can develop 46 Nm while momentarily drawing 21 A, which supports breakout force during indexing moves. The motor has a total mass of 40.2 kg, so the mounting structure must support the load during both installation and operation. Power conductors up to 4 × 4.0 mm² and a single-turn STG encoder connection complete the electrical interface. The brake circuit and feedback connection allow the motor to remain integrated within closed-loop axis control.
