SF-A4.0125.030-14.155

The Bosch Rexroth Indramat SF-A4.0125.030-14.155 from the SF Servo Motors series delivers a compact, high-precision solution for demanding motion control tasks. Designed for severe environmental conditions, the motor boasts Ingress Protection (IP) IP67 and integrates a robust Flange Size 142 mm interface. Its precision machined housing accommodates Shaft Dimensions 24 x 50 mm and a Max Length Without Holding Brake 277 mm, ensuring seamless installation in space-constrained drive assemblies. With its rugged construction and optimized form factor, this servo motor excels in applications where reliability and repeatability are paramount.

At the core of the SF-A4.0125.030-14.155 is a finely tuned electromagnetic design that delivers a Locked-rotor Torque of 14.5 Nm and a Locked-rotor Current At M0 of 5.2 A, providing rapid acceleration from standstill. Its torque generation is governed by a Torque Constant of 2.8 Nm/A and a Rated Speed of 1500 min⁻¹, yielding smooth torque-to-speed characteristics across a broad operating range. The rotor’s dynamic behavior is characterized by a low Moment Of Inertia of 30 x 10⁻⁴ kgm², which, in combination with the motor’s Mass Without Holding Brake of 16 kg, facilitates high responsiveness in cyclic and servo positioning tasks. Integrated within the housing is a high-resolution feedback system: the Encoder Type single-turn (STG) with multi-turn option and Encoder Precision/resolution of 20 angular seconds/8 million increments per revolution guarantee sub-microradian positioning accuracy and rapid commutation for brushless operation.

To secure loads and maintain positional integrity, the motor incorporates a reliable holding brake with a Holding Brake Torque of 18 Nm. This brake operates on a Brake Supply Voltage of 24 V ±10% with residual ripple ≤ 5% and draws a Rated Current of 0.7 A, adding only 1.04 kg to the overall mass while delivering secure engagement under power-off conditions. Combining industrial-grade ingress protection, precision encoder feedback, and robust electromechanical braking, the SF-A4.0125.030-14.155 is ideally suited for advanced industrial automation systems, high-speed packaging machines, and precision robotics where uptime and accuracy are non-negotiable.
