Product Description:

Bosch Rexroth Indramat manufactured the SF-A4.0230.030-00.071 servo motor for its SF Servo Motors series. As a frameless drive element, it couples directly to designated drive modules and delivers controlled rotary motion for packaging axes, printing cylinders, or material-handling gantries. The unit converts drive current into mechanical output through permanent-magnet excitation and resolver feedback, providing precise positioning and speed regulation in CNC and assembly equipment.

The motor operates at a rated speed of 3000 rpm, which is the continuous shaft velocity under nominal load without exceeding thermal limits. A torque constant of 1.57 Nm/A links commanded phase current to produced torque, enabling predictable control loop tuning. The drive electronics must supply a DC link of 670 V for proper operation. Mounting uses a flange that measures 142 mm across and complies with IEC 72-2 / DIN 42 948, allowing installation on standardized gearboxes or machine plates. An enclosure rating of IP67 protects the internal windings from dust ingress and temporary water immersion, supporting use on washdown lines or dust-laden production floors.

During startup, the stator can withstand a locked-rotor torque of 22 Nm while drawing a locked-rotor current of 14 A; these values indicate initial acceleration capability and help size current-limited drives. Mechanical durability is supported by a shock endurance of 6 g, allowing the motor to remain operational on machinery exposed to sudden impacts or rapid tool changes. Acoustic emissions stay below 58 dB(A) when measured at one meter, which helps meet shop-floor noise targets. The IM B5 construction uses a horizontal shaft with a face-mounting flange. The motor is compatible with DM30K/30A or DM45A/85B inverter modules that operate at 4 kHz or 8 kHz switching frequencies.
