Product Description:
The SF-A5.0460.030-14.000 is a synchronous AC servo motor developed by Bosch Rexroth Indramat within the SF Servo Motors series. Designed as a compact rotary axis drive, this motor converts controlled electrical energy into precise mechanical motion. It is suited for positioning tables, pick-and-place heads, and other numerically controlled equipment used in industrial automation. In closed-loop operation, a compatible servo drive can use the motor for accurate speed and position control.
With a rated speed of 3000 rpm, the rotor reaches application velocity quickly while remaining within the continuous operating range supported by the connected drive. When the shaft is prevented from turning, it can generate a locked-rotor torque of 46 Nm and draw a stall current of 29 A; these values are useful when selecting overload protection and sizing power stages. During normal acceleration, torque rises in proportion to current according to the torque constant of 1.58 Nm/A, which helps the controller predict load response accurately. Position feedback is provided by an optical encoder that delivers 8 million increments per revolution of resolution, and its angular accuracy of ±20 arc-seconds supports fine interpolation in high-precision motion paths. The listed rotor inertia moderates speed changes so servo tuning can balance responsiveness with stability.
Mechanical integration is simplified by a square flange that measures 190 mm on each side and a smooth Ø32 × 58 mm shaft that mates with standard couplings. The square flange supports direct mounting on machine plates or gear housings. The permanent-magnet holding brake supplies 56 Nm of static torque and is energized from a 24 VDC ±10% source that tolerates up to 5% ripple, while brake release current is limited to 1.33 A. Overall motor length, including the brake assembly, is 428 mm, and the complete unit weighs 40.2 kg, which affects cantilever loading and mounting hardware selection. The holding brake is intended to keep the axis stationary when drive power is removed.
