Product Description:
The SG-A3.150.024-03.000 is a brushless servo motor built by Bosch Rexroth Indramat as part of the SG Synchronous Servo Motors series. Intended for closed-loop axis drives, the unit converts electrical energy into precise rotary motion for positioning tasks in machining centers, packaging equipment, and automated assembly lines. Its compact form, flange mounting pattern, and resolver feedback allow straightforward integration with Indramat controllers while maintaining high dynamic accuracy. The brushless design reduces mechanical wear because electronic commutation eliminates the need for brushes and their associated contact surfaces.
At standstill, the motor can deliver a static torque of 16.6 Nm, giving machines sufficient holding force during dwell periods. That torque is produced while drawing a standstill current of 18.2 A, which establishes the continuous current requirement for the drive amplifier. During motion, the rotor reaches a nominal speed of 2700 rpm, so linear axes can achieve moderate throughput without overspeeding the mechanical transmission. An integrated permanent-magnet brake uses 24 V DC with a tolerance of ±10% for electrical release, allowing the shaft to lock when power is removed. Mechanical attachment uses a 140 mm square flange, which matches common IEC interfaces and simplifies coupling to a gearhead or machine frame.
The housing has an IP65 protection rating, preventing dust ingress and low-pressure water jets from reaching the windings. The permitted ambient temperature range is 0 to 40 °C, allowing the motor to operate in standard production areas without derating. The rotor is balanced to vibration severity Grade N in accordance with DIN ISO 2373, keeping oscillation within permissible limits and reducing bearing wear. The motor uses Class F insulation, which tolerates winding temperatures up to 155 °C, while an embedded NTC thermistor reports stator temperature to the controller. Heat leaves the frame through natural convection, eliminating the need for a separate cooling fan. SmCo magnets preserve magnetic flux as temperature changes during operation. The keyed shaft complies with DIN 748, and the PUR-sheathed cables support drag-chain movement at acceleration rates up to 5 m/s² and travel speeds up to 100 m/min.
