MAC AC Servo Motors
Rated 4.1 stars (6 total reviews)
The MAC093B-0-GS-2-C/130-B-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it is supplied in size 093 with the B-length housing. Cooling is provided by natural convection, and the GS winding is paired with tachogenerator feedback for speed control. The power connector sits on side B, and because a blocking brake is not present the installation must rely on external holding devices when the shaft must stay fixed.
At standstill the motor delivers a continuous torque of 14.5 Nm while drawing 38 A; this performance is supported by the GS winding and a torque constant of 0.388 Nm/A at 20 °C. For transient demands the drive may supply up to 192 A, giving extra acceleration margin before thermal limits are reached. Speed feedback is produced by a standard-quality tachogenerator that outputs 1.5 V per 1000 min⁻¹, allowing analog controllers to regulate velocity precisely. The electrical circuit exhibits a thermal time constant of 50 minutes, so current overloads must be timed accordingly.
Mechanical and magnetic parameters govern operation at the nominal speed of 4000 min⁻¹. A rotor inertia of 0.0029 kg·m² supports rapid changes in speed without excessive controller gain adjustments, and the 130 mm centering diameter ensures precise shaft alignment. The overall mass is 16.5 kg, giving the frame sufficient thermal capacity for continuous duty. Stator characteristics include a phase inductance of 2.0 mH and a winding resistance of 0.136 Ω; together they shape current rise time, copper loss, and dynamic stiffness during closed-loop operation.
