Product Description:

Bosch Rexroth Indramat manufactures the SF-A3.0093.030-10.015 as a member of its SF Servo Motors series. The unit is a brushless synchronous motor designed to deliver precise torque and velocity commands under servo drive control. It interfaces with drive amplifiers used in automated assembly stations, robotic axes, and material-handling machines, translating electrical setpoints into controlled mechanical rotation for positioning and process speed regulation.

Electrically, the motor is energized from a DC bus that reaches 670 V, a level that permits high power density without increasing current demands. Under rated excitation, it reaches a top speed of 3000 rpm, making it suitable for servo drives that follow 1 kHz position loops. When the shaft is blocked, the winding draws 6.0 A and can generate 8.1 Nm of startup torque. These values show the peak load seen by the drive electronics and the mechanical coupling during indexing. The electromagnetic design produces 1.35 Nm/A of torque per ampere, so required current rises in proportion to commanded torque. Heat generated by these currents is removed by natural convection, and the absence of an integrated brake keeps overall inertia low for fast acceleration.

The rotor stores 16 × 10⁻⁴ kgm² of inertia, balancing quick response with vibration damping for medium-mass payloads. A permissible axial thrust of 133 N protects the bearings when gearboxes or screw drives impose end loads. The motor uses a 116 mm square flange, enabling exchange with other IEC-coded servo frames. During transport or operation, the housing withstands shocks up to 6 g, helping protect the internal magnet stack. For feedback, a high-density encoder delivers 8 million increments per revolution with ±20 arc-second precision, allowing the controller to resolve very small moves for fine pick-and-place cycles.
