Product Description:

The SF-A4.0230.030-00.010 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SF Servo Motors series. In industrial automation, this type of motor converts commanded current into controlled rotary motion so positioning tables, pick-and-place heads, and feed drives reach target speeds and angles with closed-loop accuracy. Its electrical design allows direct connection to Rexroth digital drives that modulate phase current for torque generation and feedback-based velocity control. This arrangement supports repeatable starts, stops, and speed changes in machines that rely on coordinated axis motion.

The motor’s nominal shaft velocity reaches 3000 rpm, a speed that suits machine tool and packaging axes that require medium-fast cycles. Under drive current, the electromagnetic circuit delivers torque in proportion to the torque constant of 1.57 Nm/A, which lets the controller estimate mechanical output from commanded amperes. If the rotor is prevented from turning, it can resist a static load of 22 Nm while drawing a locked-rotor current of 14 A. These values are useful when matching the motor to a compatible drive and the expected load profile. A square 142 mm mounting flange provides a standardized interface for machine mounting and helps simplify mechanical integration.

Long-term reliability is indicated by a bearing service life of 20,000 h, which supports continuous-duty operation over extended service intervals. The assembly tolerates mechanical shocks up to 6 g, allowing use on equipment where abrupt forces can occur during machine motion. Positioning accuracy during installation is supported by a pilot diameter of Ø130 j6, and threaded tooling alignment is accommodated by a center hole specified as DIN 332-DS M8. These mounting features help keep the motor centered on the machine interface and make shaft alignment easier during installation.
