Product Description:

The MAC90C-0-G-4C/110-A-1/WI520/S01 is an AC servo motor built by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive current into controlled shaft rotation for position and velocity tasks in industrial automation such as gantries, tool heads, and packaging axes. The motor works with external servo amplifiers through analog command signals, allowing tight speed loops while maintaining mechanical interchangeability inside protected machine envelopes. This arrangement supports accurate motion control while keeping the power stage and command processing in the separate drive system.

It reaches a nominal speed of 3000 rpm under rated voltage, giving consistent cycle times for fast-moving axes. At standstill, the shaft can deliver 9.6 Nm while drawing 24.8 A, which helps size the drive for static load holding or low-speed cutting and forming tasks. The torque constant is 0.43 Nm/A, and the stator uses a winding inductance of 1.5 mH with 0.24 Ω resistance to shape current rise and response. A centering diameter of 110 mm and a total mass of 23 kg support flange alignment and inertia matching, while the 1250-line encoder provides fine feedback to the external controller. The housing meets IP65, which keeps dust and water jets away from internal motor components. These electrical and mechanical values help the motor respond smoothly during repeated starts, stops, and low-speed positioning.

Dynamic events are handled through a peak pulse rating of 196 A, allowing short bursts of acceleration without loss of synchronization. For power-off holding, an integrated brake produces 6.5 Nm when energized at 24 VDC and draws 0.7 A to maintain clamp force on vertical or indexing axes. This brake is useful when the load must remain stationary after shutdown instead of relying on drive torque alone. Rotor inertia of 0.0053 kg·m² balances quick response with vibration damping, and a 60-minute thermal time constant indicates gradual temperature rise during extended duty. That behavior helps the motor handle changing load conditions without abrupt thermal buildup during normal cyclic operation.
