Product Description:

The SF-A2.0020.060-14.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the SF Servo Motors series. Designed for positioning and velocity loops in CNC stations, pick-and-place gantries, and material-handling axes, the unit converts electrical power into controlled rotary motion while supplying high-resolution feedback to the drive controller. Its synchronous design supports quick response during repeated starts, stops, and direction changes. This makes the motor suitable for automated equipment that depends on accurate speed regulation and repeatable axis movement.

The motor reaches a rated speed of 6000 rpm, permitting rapid indexing in short-cycle machinery. A square flange of 100 mm matches common gearbox and mounting patterns for straightforward mechanical integration. Connection to a shared DC bus at 670 V allows the winding to produce commanded torque with moderate current, which helps improve overall system efficiency. Position data comes from a single-turn absolute encoder with a precision of ±20 arcsec and a resolution of 8,000,000 increments per revolution, so the controller can interpolate fine motion steps for sub-micron linear travel. The electromagnetic design provides a torque constant of 0.74 Nm/A, giving predictable torque output across the operating range.

An integrated holding brake delivers 3.2 Nm of static torque and is powered by a 24 VDC supply that draws 0.56 A during engagement, keeping vertical axes secure when power is removed. The motor can draw a locked-rotor current of 2.7 A and produce 2.0 Nm of stall torque, which helps the drive overcome static friction at startup. With a mass of 5.8 kg, an overall length of 217 mm, and a 14 × 30 mm keyed shaft, the motor adds limited inertial load to linear slides while maintaining a secure mechanical connection.
