Product Description:
The SF-A4.0172.030-10.015 is a synchronous motor manufactured by Bosch Rexroth Indramat and supplied within the SF Servo Motors series. Designed for closed-loop industrial drives, the unit converts electrical power into controlled mechanical rotation to position or regulate machine axes with high repeatability. It mounts according to construction type IM B5, so the flange carries the entire radial load while the shaft remains unsupported by feet. With this configuration, the motor integrates directly into compact machining centers, pick-and-place stations, and automated handling modules.
Under rated operating conditions, the motor reaches a speed of 3000 rpm, making it suitable for moderate-to-high velocity positioning tasks. Starting torque is 18 Nm and is available when the rotor is blocked without thermal overload. A torque constant of 1.38 Nm/A gives the proportional relationship between phase current and mechanical torque, simplifying current loop control in the drive. Mechanical integration is based on a flange diameter of 142 mm; the overall housing length is 309 mm, and the assembly mass is 19 kg. Rotor inertia of 40 × 10⁻⁴ kg·m² balances acceleration capability with load damping, while two integrated NTC sensors monitor winding temperature for drive protection.
The motor operates from a drive DC link rated at 670 V. During initial energization, the drive may draw a locked-rotor current of 13 A, so supply components must be sized for that inrush. Position feedback relies on an absolute encoder that delivers 8 million increments per revolution with a precision of ±20 angular seconds, enabling sub-arc-minute positioning across the full speed range. This encoder removes the need for homing routines and maintains reference after power loss, reducing cycle time in multi-axis gantries.
