MAC093B-0-GS-2-C/130-B-0/S001 by Bosch Rexroth Indramat

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 drive controllers, the motor supplies closed-loop rotary motion to conveyor zones, pick-and-place heads, and other industrial axes that require repeatable velocity and position. Natural convection carries heat away from the stator, and the power connector located on side B positions cabling toward the machine interior. Integrated tacho feedback delivers a proportional voltage signal for speed monitoring.

The motor can hold a load at standstill with a continuous torque of 14.5 Nm; this value represents the mechanical twisting force available without exceeding permissible winding temperature. To sustain that output, the drive must supply approximately 38 A of continuous current, a figure that determines conductor sizing and converter rating. During normal operation, the rotor can accelerate to a nominal speed of 4000 rpm, establishing the base frequency for application gearing. Electromagnetic conversion efficiency is characterized by a torque constant of 0.388 Nm/A, so each ampere of phase current produces just under four-tenths of a newton-meter. Electrical dynamics are influenced by a phase inductance of 2.0 mH, which shapes current rise time and affects servo bandwidth.

Transient demands are met by a peak phase current of 192 A, giving the axis short-term torque reserve for rapid indexing or shock loading. The rotor inertia of 0.0029 kg·m² provides a moderate compromise between quick acceleration and load stability, a useful trait when matching the motor to low-mass tooling. Thermal behavior is governed by a time constant of 50 min; this long heat soak interval allows intermittent overloads without immediate temperature rise. A total mass of 16.5 kg and a centering diameter of 130 mm simplify rigid flange mounting, while the absence of a blocking brake leaves position holding to the external drive.
