Product Description:

The MAC093B-0-JS-C/110-A-0 is an AC servo motor produced by Bosch Rexroth Indramat and positioned within the MAC AC Servo Motors series. It is supplied as a motor for analog drives and is intended to deliver controlled rotary motion to machine axes, conveyors, or tooling fixtures in industrial automation cells. The unit relies on natural convection for heat removal, and the power terminals are located on side A to simplify cable routing during installation. This configuration suits general automation equipment that uses an external amplifier for current and speed regulation.

At standstill, the motor can supply 14.5 Nm of continuous torque while drawing 27 A of current, so the drive must be sized to maintain that current without exceeding thermal limits. Under rated excitation, the rotor can operate at 3000 rpm, which is suitable for medium-inertia machine shafts. For rapid index moves, the control can command up to 134 A of peak pulse current, allowing the electromagnetic system to generate short bursts of torque above the continuous level. Because each ampere contributes roughly 0.554 Nm/A, commanded current scales in a predictable way with motor torque. This helps the controller produce consistent acceleration and positioning response during motion.

A rotor inertia of 29 × 10⁻⁴ kg·m² helps moderate speed changes when the axis is coupled to lighter loads. The front face uses a 130 mm flange, and a 110 mm centering pilot helps keep the motor aligned with gearboxes or bell housings. Heat accumulates gradually, reaching its steady-state thermal condition only after 50 min, which supports intermittent duty without added cooling hardware. The motor mass of 16.5 kg adds structural stiffness and helps reduce vibration transferred from the machine frame.
