MAC AC Servo Motors
Rated 4.6 stars (14 total reviews)
The MAC093C-0-FS-3-C/110-B-0/S001 is an AC servo motor from the MAC AC Servo Motors series and is intended for analog drives that position and regulate rotary axes in automated machinery. It uses the 093 frame with the longer C housing and the FS winding code. Cooling is done by natural convection, so heat is removed from the stator without an external fan. The motor includes tacho feedback and a second shaft end for external transducers, it has no blocking brake, and its power leads connect through a connector on side B. A centering diameter of 110 mm helps align the motor on a mounting flange.
The motor delivers a continuous stall torque of 19.5 Nm when housing temperature remains within rated limits, and it draws a continuous stall current of 35 A to maintain that load. Under rated excitation, the rotor reaches a nominal speed of 3000 rpm, which supports direct coupling to pumps, spindles, or indexing tables without gear reduction. For short acceleration demands, it can accept a peak pulse current of 173 A, allowing brief torque increases above the continuous level. The enclosure is rated IP65, which keeps out dust and resists low-pressure water jets. Thermal rise is influenced by a 50-minute thermal time constant during extended duty cycles.
Speed feedback is supplied by a standard tacho generator with an output of 3 V/1000 rpm, which supports analog velocity loops in legacy drive controllers. The motor has a torque constant of 0.579 Nm/A, so current in the windings is converted into predictable shaft torque. Dynamic response is affected by a stator inductance of 2.9 mH and a winding resistance of 0.175 Ω, which influence current rise and resistive heating. These electrical characteristics affect how the motor responds in applications that require precise analog control without a holding brake.
