Product Description:
The SF-LA3.0068.030-14.059 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. It uses a 116 mm square flange and has an overall length of 294 mm, including its spring-applied brake, so it fits compact machine spaces and gantry axes. Its integrated absolute encoder supplies position data with ±20 arc-second precision, which eliminates homing cycles after power loss. This allows the axis to return to operation without a reference move after an interruption. Intended for closed-loop motion systems, the motor delivers controlled torque and speed to automated packaging, pick-and-place, and conveying axes, while the mechanical brake secures the load at standstill.
Under nominal conditions, the rotor reaches 3000 rpm, and torque production scales with the motor constant of 1.36 Nm/A, allowing drive current to correspond closely to output torque. A DC bus of 670 VDC feeds the inverter stage so field-oriented regulation remains stable during rapid acceleration. High-density optical feedback returns 8 million increments per revolution, giving the controller fine resolution for smooth interpolation. That feedback density also helps support smooth low-speed motion and accurate command tracking. During idle or emergency power-off conditions, a spring-applied brake supplies 10.0 Nm of holding torque to prevent shaft movement on vertical or indexing axes.
Total inertia seen by the drive includes the rotor’s 11 × 10⁻⁴ kg·m² plus an additional 1.06 × 10⁻⁴ kg·m² contributed by the brake, which affects how quickly the axis can accelerate or settle after a move. If the shaft is blocked, the windings may carry a locked-rotor current of 5.0 A, generating 6.8 Nm of stall torque until protective limits stop operation. The brake coil draws 0.66 A from a regulated supply of 24 VDC ±10% with 5% ripple during engagement. The complete assembly weighs 9.6 kg, which keeps the motor manageable during mounting. These operating values support controlled motion where accurate stopping and stable position holding are required.
