Product Description:

The SF-A5.0250.030-14.000 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the SF Servo Motors series. In industrial automation, it acts as the drive element that translates current from a servo amplifier into precise rotary motion, allowing controllers to carry out positioning, speed control, and contouring tasks on packaging lines, handling robots, and machine-tool feed axes. Its electromagnetic design supports rapid acceleration and deceleration while maintaining the accuracy required for closed-loop motion profiles. This type of motor is commonly used where repeatable movement and stable torque response are needed across changing load conditions.

This model supports continuous operation at a rated speed of 3000 rpm under nominal load. During a locked-rotor condition, the motor can apply up to 23 Nm of stall torque while drawing a locked-rotor current of 16 A. The electromagnetic torque constant is 1.44 Nm/A, so each ampere of phase current produces a proportional amount of shaft torque for predictable response. Dynamic behavior is influenced by a rotor inertia of 83 × 10⁻⁴ kg·m², which helps balance quick response with stable control when the driven load changes abruptly.

A flange size of 190 mm suits standard machine mounting patterns, while the ground steel shaft measures 32 × 58 mm for connection to couplings or pulleys. Stator leads use insulation rated for 600/1000 VAC, which helps protect the windings during operation with long motor cables and typical servo drive output conditions. Power is delivered through a compact 1.25/1.5 (8-pin) connector that supports secure electrical connection and helps maintain shielding continuity. The connector layout also helps keep power wiring compact in enclosed machine assemblies, and the shaft format supports direct mechanical integration with common transmission components.
