Product Description:

The SF-A4.0172.030-14.070 belongs to the SF Servo Motors series produced by Bosch Rexroth Indramat. It is a permanent-magnet synchronous motor intended for closed-loop industrial automation where precise position and velocity control are required. When connected to a compatible drive, the motor converts electrical power into controlled mechanical rotation that can be coordinated with sensors and actuators on an assembly line or handling axis. Its synchronous design supports repeatable motion, which makes it suitable for equipment that depends on stable speed response and accurate positioning.

The motor is built on a 142 mm flange and uses the IM B5 mounting arrangement, so the housing bolts directly to a machine face while the shaft remains available for couplings or pulleys. Under nominal operating conditions, the rotor reaches a rated speed of 3000 rpm, allowing the motor to support moderate linear feed rates without requiring excessive gearbox reduction. During startup or a sudden stall, the drive may supply a locked-rotor current of 13 A, which produces a locked-rotor torque of 18 Nm to help overcome static friction and inertial resistance. Continuous torque production is supported by a torque constant of 1.38 Nm/A, so motor output can be related directly to measured phase current during normal control.

An electromechanical brake provides a brake holding torque of 18 Nm, giving the motor added holding capability when the axis must remain stationary. The brake releases when its coil is energized with a brake rated current of 0.7 A from a 24 VDC supply. The brake adds only 1.04 kg to the motor mass and contributes 3.1 × 10⁻⁴ kg·m² to total inertia, so quick indexing motion remains practical. Two NTC temperature sensors embedded in the stator provide thermal feedback for drive-based derating or shutdown, and integrated motor memory stores identification data for automatic recognition by the controller.
