Product Description:

The SF-B5.0460.020-00.107 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. As a rotary actuator, it converts electrical energy into controlled torque and speed for positioning tasks in automation lines, packaging stations, and handling modules. Integrated feedback enables the drive controller to command precise movements, making the unit suitable for closed-loop motion axes where repeatability and quick response are required.

The following electrical and mounting values affect how the motor is used in a drive system. Its DC link can accept up to 670 V, which is the maximum intermediate-circuit voltage the paired inverter must supply. A flange diameter of 190 mm sets the mounting interface, ensuring the housing seats accurately against gearboxes or machine frames. When the rotor is blocked, the motor can deliver a locked-rotor torque of 46 Nm, supplying sufficient breakaway force for static loads. Under continuous operation, the shaft reaches a rated velocity of 2000 rpm, balancing throughput and bearing stress. The electromagnetic design yields a torque constant of 2.2 Nm/A, so the controller can predict output torque directly from phase current for linear current-to-torque regulation.

Further connection data supports cabinet wiring and diagnostic protection without repeating earlier values. A locked-rotor current of 21 A guides drive sizing for peak demand during indexing. Power conductors are routed through a cable rated at 4 × 4.0 mm², and the mating connector provides 8 pins to separate power and feedback paths. The signal side employs an output connector size of 1.5, matching standard servo plug dimensions. An absolute-value encoder supplies position data, while two integrated NTC sensors monitor winding temperature to prevent thermal overload.
