Product Description:

The SF-A5.0460.045-10.037 is a permanently excited synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the SF Servo Motors series. When connected to a matching drive, it converts high-voltage DC into controlled mechanical output for positioning gantries, indexing tables, and automated packaging axes that require precise motion and reliable feedback. Its synchronous design supports responsive acceleration and stable tracking during repeated machine cycles. The motor is intended for compact installations that need high resolution, sealed construction, and consistent performance during continuous industrial operation.

Power is taken from a DC link of 670 V, which matches high-bus multi-axis converters used in servo systems. The generated electromotive force is sinusoidal, which helps reduce cogging and supports smoother low-speed torque. An absolute encoder accuracy of ±20 angular seconds helps limit positional error, and its internal scale provides 8 million increments per revolution for fine feedback resolution during speed and position control. A square 190 mm flange provides a standardized mechanical interface for direct installation on compatible machine faces. The rotor can withstand 46 Nm of locked-rotor torque during static clamping or rapid starts.

B5 flange mounting simplifies alignment to gearheads, and the motor is supplied without a mating connector so cable sets can be selected to suit local routing requirements. A smooth 32 x 58 mm shaft supports coupling to backlash-free hub clutches, which is useful where low backlash is needed at the load. Absolute position feedback eliminates homing after power returns, and the motor operates at a rated speed of 4500 rpm for fast axis movement. The housing carries an IP67 rating, allowing washdown without supplemental covers. With a mass of 42.00 kg, the motor remains suitable for overhead axes while supporting a torque-dense magnetic circuit.
