Product Description:
The SF-A4.0230.030-14.019 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. As a rotary actuator, it converts drive current into controlled torque for positioning tasks in packaging lines, printing machinery, and material-handling axes. The motor has a built-in electromagnetic holding brake for secure load retention when the drive is disabled, which is useful on axes that must stay in place during a stop or power interruption. An absolute encoder supplies precise position data, so the controller can restore position after power loss without a homing routine.
This model reaches a rated speed of 3000 rpm, permitting rapid cycle times without mechanical gearing in many direct-drive applications. A torque constant of 1.57 Nm/A links drive current directly to output torque, which makes motor response easier to predict during controlled acceleration and holding. The square flange measures 142 mm, providing a standard mounting interface for IM B5 face installation, and the windings are fed from a bus at 670 VDC for high power density with moderate phase current. When the brake is engaged, it can resist up to 18 Nm of load torque, and during startup the motor can draw a locked-rotor current of 14 A as it develops breakaway torque.
The housing is sealed to IP67 on every side except the shaft output, supporting washdown environments and dusty machining cells where the motor body is exposed to moisture or debris. At standstill, the stator can deliver a locked-rotor torque of 22 Nm, which is the maximum load the axis can overcome from rest before motion begins. Dynamic response is influenced by a rotor inertia of 54 × 10⁻⁴ kg·m², while the brake adds only 3.1 × 10⁻⁴ kg·m² of inertia so the assembly does not become excessively sluggish. The brake coil is energized from 24 VDC and draws 0.7 A during hold, and no mating power connector is supplied so cabling must be sourced separately to suit the installation.
