MAC AC Servo Motors
Rated 4.3 stars (27 total reviews)
The MAC112D-2-FD-4-C/130-A-0/WI520LV/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drives, it converts commanded armature current into controlled mechanical output in automated presses, gantries, and material-handling axes. Type-coded winding FD, power routing on side A, and axial surface cooling with a 115 V blower integrate easily into standard control cabinets. The motor operates without a blocking brake, so position holding must be assured by external clamps or drive torque, while tachometer or incremental encoder feedback supplies real-time velocity data to the controller.
A continuous torque of 38.0 Nm can be produced at standstill when the winding is fed with the rated current of 56.0 A; this pairing defines the thermal load that servo amplifiers must sustain during static positioning. Under rated excitation the shaft reaches its nominal speed of 2000 min⁻¹, and short acceleration bursts are supported by a peak current ceiling of 260 A. The phase inductance of 1.8 mH limits the current ripple and influences the bandwidth that can be achieved by the analog current loop. Together with a torque constant of 0.760 Nm/A and a tacho output of 3 V per 1000 min⁻¹, these electrical figures allow drive tuning for stable, low-jitter operation.
Mechanical integration relies on a centering diameter of 130 mm and a DIN 6885 keyway, so the shaft couples directly to standard pulleys or pinions. The rotor inertia of 0.0230 kg·m² balances dynamic response with load matching, while the overall mass of 59 kg must be supported by the mounting structure during acceleration events. Heat absorbed during cyclic duty dissipates slowly; the thermal time constant is 120 min, which defines permissible overload duration before winding temperatures reach their limit.
