Product Description:

The SF-A3.0093.060-10.050 is a servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. This permanently excited synchronous unit supplies closed-loop rotary actuation in industrial automation where precise speed and torque regulation are needed for pick-and-place devices, light machining centers, and auxiliary spindles. An integrated absolute encoder feeds continuous position data to the drive controller, which supports coordinated multi-axis motion without separate homing moves. This makes the motor suitable for dynamic axes that require repeatable positioning and stable response under changing loads.

The motor reaches a rated speed of 6000 rpm, allowing fast cycles without mechanical gearing. Its torque constant of 0.67 Nm/A links drive current directly to output torque, which helps keep current response predictable during operation. During startup or blockage conditions, the winding can accept a locked-rotor current of 13.5 A, producing a stall torque of 9.1 Nm so machines can overcome static friction reliably. Power is supplied from a DC link rated at 670 V, matching common high-voltage servo inverters and reducing current demand on the supply side. The synchronous design with permanent magnets keeps efficiency high and motor response linear across the usable speed range.

Continuous service is permitted up to 40 °C ambient temperature, and the winding insulation system can tolerate temperatures up to 155 °C before its thermal limit is reached. Shock resistance of 6 g helps protect the rotor and magnets against transport loads or machine impacts, while precision deep-groove bearings are rated for 20000 h of service before replacement is typically required. Two embedded NTC temperature sensors report thermal status directly to the drive so operating current can be reduced automatically as the motor approaches its thermal limit. This added temperature monitoring helps protect the stator during sustained duty and repeated acceleration.
