Product Description:
The SF-A4.0230.030-10.019 servo motor is manufactured by Bosch Rexroth Indramat as part of the SF Servo Motors series. This three-phase permanent-magnet unit is intended to drive linear or rotary machinery where closed-loop speed and position control are required in industrial automation. It fits the mechanical envelope used for the series, allowing direct mounting to gearboxes or machine frames and electrical connection to Rexroth drive converters without control software changes.
Its electrical circuit is designed for a DC link of 670 V, letting the connected inverter deliver full field-oriented control within standard high-voltage cabinets. During startup, the stator can draw a locked-rotor current of 14 A, producing a locked-rotor torque of 22 Nm for overcoming static friction in tight transmission trains. Once rotation begins, the rotor reaches its rated speed of 3000 rpm under continuous load. The motor interfaces to the machine through a square flange measuring 142 mm, which matches common Rexroth housing bolt patterns. The frame is made from aluminum to reduce mass and improve thermal conductivity, and the output shaft is smooth to mate with clamp or keyless couplings.
Torque generation per phase is characterized by a constant of 1.57 Nm/A, helping calculate current limits for dynamic cycles. Internal temperature sensing relies on two NTCs, which feed the controller with winding and housing data for derating or shutdown before insulation limits are reached. The assembly withstands impacts of up to 6 g, supporting installation on stamping lines or indexing tables subject to recoil. A minimum service life of 20000 h is expected when the motor operates within its thermal envelope and vibration class. No mating connector is supplied, allowing the use of field-mount plugs compatible with existing harnesses.
