Product Description:

The Bosch Rexroth Indramat MAC025C-0-QS-3-E/040-A-0 is a brushless AC servo motor in the MAC AC Servo Motors series. It converts drive commands into controlled rotary motion for positioning tables, pick-and-place arms, and light conveying equipment throughout industrial automation. A permanent-magnet rotor, a low-inertia stator stack, and integrated feedback give the unit the speed control accuracy expected of servo technology while preserving a compact footprint suitable for densely packed machine frames. Its compact build also helps reduce moving mass on small handling axes, which can improve acceleration and settling behavior.

Thermal regulation is handled by natural convection, so heat dissipates across the housing surface without auxiliary blowers or liquid channels. Speed is reported through tacho feedback, and the motor also has a second shaft end for external couplings. The motor is supplied without a blocking brake, so static holding torque must come from the drive or an external lock when the axis is stopped. The 025 length code indicates a short active length that lowers moment of inertia for rapid start-stop cycles. Frame designation C sets the flange and pilot dimensions used by this housing size.

Power enters the windings through a connector on side A, placing the mains lead on the same face as the feedback connection for simpler cable routing in compact enclosures. Classified as a motor for analog drives, the unit is intended for voltage-controlled amplifiers that close the velocity loop with the built-in tachometer signal. This arrangement supports older control platforms that rely on analog command structure rather than digital fieldbus communication. It also helps keep the surrounding drive hardware straightforward where a separate digital feedback interface is not required. That makes the motor a practical fit for retrofit machinery that still uses analog servo electronics.
